Abstract
This essay provides a theoretical reflection on the challenges of meeting the Sustainable Development Goals of the 2030 Agenda, considering its motto of "leave no one behind". To exemplify these challenges, we discuss noncommunicable diseases (NCDs), one of the main issues on the global health agenda before the COVID-19 pandemic, and the political and economic dimensions that determine their presence and global spread. After a brief overview of NCDs, the text seeks to answer three questions: In "Leaving no one behind?" we list some themes to reflect on how and who has historically been left behind, delving a little deeper into the examples in "Who has been left behind in the world?" and "Who has been left behind in Brazil?". Using data from the most relevant and recent literature on the subject, we discuss the challenges and some ways to leave no one behind in a world where the mean of production has historically made some social groups vulnerable, especially black and Indigenous populations. In our final remarks, we draw inspiration from the Sankofa ideogram to remember that the answers to the sustainable development we seek may lie somewhere in our most primordial and traditional past. And that it is necessary to invest on building new paths from different worldviews and approaches to epistemology on the other side of the abyssal line.

Abstract
Agriculture has gained increasing importance in response to the continuous growth of the world population and constant need for food. To avoid production losses, farmers commonly use pesticides. Mancozeb is a fungicide used in agriculture as this compound is effective in combating fungi that harm crops. However, this fungicide may also produce damage to non-target organisms present in soil and water. Therefore, this study aimed to investigate the influence of exposure to mancozeb on survival rate, locomotor activity, behavior, and oxidative status utilizing adult zebrafish (Danio rerio) as a model following exposure to environmentally relevant concentrations of this pesticide. The experimental groups were negative control, positive control, and mancozeb (0.3; 1.02; 3.47; 11.8 or 40 μg/L). Zebrafish were exposed to the respective treatments for 96 hr. Exposure to mancozeb did not markedly alter survival rate and oxidative status of Danio rerio. At a concentration of 11.8 μg/L, the fungicide initiated changes in locomotor pattern of the animals. The results obtained suggest that the presence of mancozeb in the environment might produce locomotor alterations in adult zebrafish, which subsequently disrupt the animals' innate defense mechanisms. In nature, this effect attributed to mancozeb on non-target organisms might result in adverse population impacts and ecological imbalance.

Abstract
We aimed to examine the responses of pollution biomarkers in feral fish from Astyanax genus collected at three hydrographic regions in southern Brazil and the capacity of these tools to differentiate between various levels of contamination. To achieve this, levels of organochlorine pesticides (liver), as well as the biomarkers AChE (muscle and brain), TBARS (liver), and EROD (liver) were assessed. Collections were conducted in four municipalities (Alegrete, Caraá, Lavras, and Santa Vitória) during 1 year, encompassing winter and summer. Fish from Alegrete were the most contaminated overall, but animals sampled in Caraá, and Lavras also displayed elevated levels of current-use pesticides. Elevated levels of endosulfans, DDTs, HCHs, and current-use pesticides were accompanied by elevated levels of TBARS in the liver. Conversely, fish from Santa Vitória exhibited the highest levels of PAHs, accompanied by elevated levels of EROD in the liver and reduced levels of AChE in muscle and brain. TBARS proved to be a reliable biomarker for assessing impacts arising from pesticide accumulation, while EROD and AChE served as valuable indicators of impacts resulting from PAHs accumulation. Ultimately, the results obtained in this study demonstrate the reliable use of the proposed biomarkers for tracking biological impacts stemming from aquatic pollution using feral Astyanax as biomonitoring species.

Abstract
Pesticide use in agriculture threatens non-target insects such as bees. Considering the ecological and economic relevance of native bees, such as Scaptotrigona postica, and the insufficient studies on the effects of pesticides on their behavior and physiology, improving the current knowledge on this issue is essential. Therefore, this study investigated the sublethal effects of imidacloprid, pyraclostrobin, and glyphosate on the behavior and fat body cells of S. postica. Pesticide ingestion decreased the walking distance and mean velocity of bees compared to the control and solvent control groups. The oenocytes of the control groups were spherical, with central nuclei containing decondensed chromatin, and the trophocytes presented irregular morphology, with cells varying in shape and the cytoplasm filled with vacuoles and granules. However, bees exposed to pesticides showed extensive cytoarchitectural disruption in the fat body, such as vacuolization and shape changes in oenocytes and altered nuclei morphology in trophocytes. Moreover, pesticide exposure increased the number of atypical oenocytes and altered trophocytes, except for the PYR group, which showed a lower number of atypical oenocytes. Caspase-positive labeling significantly increased in all exposed bee groups. Alternatively, TLR4 labeling was significantly decreased in the exposed groups compared to the control groups. There was a significant increase in HSP90 immunolabeling in all exposed groups compared to the control. These findings reinforce the importance of research on the sublethal effects of low pesticide concentrations on key neotropical pollinators and prove that these toxic substances can impair their detoxification and immune defense.

Abstract
Over the last several decades, Brazil has become both the world's leading soy producer and the world's leading consumer of hazardous pesticides. Despite identified links between pesticide exposure and carcinogenesis, there has been little population-level research on the effects of pesticide intensification on broader human health in Brazil. We estimate the relationship between expanded soy production-and related community exposure to pesticides-on childhood cancer incidence using 15 y of data on disease mortality. We find a statistically significant increase in pediatric leukemia following expanded local soy production, but timely access to treatment mitigates this relationship. We show that pesticide exposure likely occurs via water supply penetration. Our findings represent only the tip of the iceberg for substantial health externalities of high-input crop production and land use change. Our results are of particular interest in developing contexts with demand for intensified food production systems and underscore the need for stronger regulation of pesticides and increased public health attention to exposure in the broader community.

Abstract
The bufonid species Melanophryniscus admirabilis is restricted to a single location in the southern Atlantic Forest, Brazil. Although the site of occurrence of M. admirabilis is covered with native forest and it is not directly exposed to pesticides application, the area is surrounded by agricultural activity. Our objectives were to evaluate possible alterations in morphological parameters (body mass, snout-vent length, and body index), metamorphosis (time to reach Gosner stages 42, 46 and to complete metamorphosis), and survival of M. admirabilis exposed to isolated Roundup® Original DI (R1: 234 and R2: 2340 µg.L-1 of glyphosate) and Boral® 500 SC, (B1: 130 and B2: 980 µg.L-1 of sulfentrazone) or mixed (R1+B1, R2+B1, R1+B2, R2+B2). Spawns of M. admirabilis were collected in natural lakes in the municipality of Arvorezinha and taken to laboratory cultivation. After the tadpoles acquired free swimming, the animals were acclimated for five days and fed ad libitum. The aquariums were contaminated with herbicides on the sixth day of cultivation, and the animals stayed in these aquariums for four days. Afterwards, the tadpoles were transferred to aquariums with clean water and monitored until metamorphosis (Gosner stage 46), when they were weighed, measured (snout-cloacal length) and cryoeuthanized. We observed no alterations in morphological parameters; however, survival was reduced in exposed groups (mortality index: 71 % in R2 and 29-64 % in mixed groups), suggesting energy allocation for metamorphosis at the expense of survival. Boral did not alter metamorphosis time. Roundup isolated and mixed with Boral altered the timing of Gosner stages 42 and 46 and reduced metamorphosis time, suggesting endocrine disruption. Thus, monitoring the presence and limiting the use of these pesticides in the area where M. admirabilis occurs can be crucial for conservation strategies.

Abstract
Pesticides are widely used in global agriculture to achieve high productivity levels. Among them, fungicides are specifically designed to inhibit fungal growth in crops and seeds. However, their application often results in environmental contamination, as these chemicals can persistently be detected in surface waters. This poses a potential threat to non-target organisms, including humans, that inhabit the affected ecosystems. In toxicologic research, the zebrafish (Danio rerio) is the most commonly used fish species to assess the potential effects of fungicide exposure, and numerous and sometimes conflicting findings have been reported. To address this, we conducted a systematic review and meta-analysis focusing on the neurobehavioral effects of fungicides in zebrafish. Our search encompassed three databases (PubMed, Scopus, and Web of Science), and the screening process followed predefined inclusion/exclusion criteria. We extracted qualitative and quantitative data, as well as assessed reporting quality, from 60 included studies. Meta-analyses were performed for the outcomes of distance traveled in larvae and adults and spontaneous movements in embryos. The results revealed a significant overall effect of fungicide exposure on distance, with a lower distance traveled in the exposed versus control group. No significant effect was observed for spontaneous movements. The overall heterogeneity was high for distance and moderate for spontaneous movements. The poor reporting practices in the field hindered a critical evaluation of the studies. Nevertheless, a sensitivity analysis did not identify any studies skewing the meta-analyses. This review underscores the necessity for better-designed and reported experiments in this field.

Abstract
Organochlorine pesticides (OCP) are legacy anthropogenic compounds known to persist for several years in the environment. The continuous use of some OCP, such as DDT, after restrictions in developing countries are cause of concern, due to their deleterious effects to marine life and humans. Studies assessing OCP contamination in coastal environments are still scarce in South America and there is a need to understand the impacts from trophic chain accumulation of these pollutants in marine life. In this study, we have assessed OCP levels in muscle and liver and estimated the biomagnification factor in several upwelling system trophic chain members, including fish, squid, and marine mammal from Southeastern Brazil. DDT degradation product DDE was the OCP detected in the highest concentrations in Franciscana dolphins (Pontoporia blainvillei), 86.4 ng·g-1 wet weight, and fish muscle and liver. In general, higher OCP levels were found in liver than in muscle, except for croaker. Biomagnification factors (BMF) of OCP in the top predator P. blainvillei and the carnivorous cutlass fish (Trichiurus lepturus) were on average between 0.2 and 1.8. Continued OCP monitoring in this region is warranted to better understand the distribution and fate of these compounds over time, with the goal to establish strategies for the conservation of local dolphin species and to assess human health risks from local coastal region populations.

Recent trends in pesticides in crops: A critical review of the duality of risks-benefits and the Brazilian legislation issue. ENVIRONMENTAL RESEARCH 2023; 228:115811.

Abstract
Due to the increasing population worldwide, in recent years, an exponential increase in agricultural practices has occurred in order to attend to the growing demand for food. Unfortunately, this increase is not associated with the supply of foodstuffs free of environmental pollutants. In Brazil, agriculture is one of the most important economic pillars, making the country one of the largest consumers of pesticides around the world. The intense use of pesticides, mainly glyphosate, 2,4-D, and atrazine, constitutes an essential factor in the viability of this great agricultural productivity. Sugarcane, corn, soybean, and citrus crops consume around 66% of the total pesticides worldwide, representing 76% of the planted area. Pesticide residues have been frequently detected in food and the environment, becoming a significant concern for human health. Monitoring programs for pesticide use are essential to reduce the potential negative impacts on the environment and improve the overall efficiency and sustainability of their use. However, in Brazil, the approval status of pesticide-active ingredients is very discrepant compared to other agricultural countries. Moreover, the duality of benefits and risks of pesticide application creates an economic and toxicological conflict. In this paper, we have critically reviewed the duality of risks-benefits of the use of pesticides in agriculture and the current Brazilian legislation issues. We have also compared this flawed legislation with other countries with high economic potential. Due to the negative environmental impacts on soil and water by the high levels of pesticides, remediation techniques, sustainable agriculture, and the development of new technologies can be considered some viable alternatives to reduce the levels in these compartments. Besides, this paper includes some recommendations that can be included in the coming years.

Abstract
INTRODUCTION Pesticides can trigger kidney disease. OBJECTIVE To describe the exposure to pesticides of patients with chronic kidney disease on dialysis. METHODS Quantitative and descriptive field research, with 90 patients with chronic kidney disease on dialysis in two hemodialysis units in the state of Santa Catarina, through the application of a structured questionnaire. Participants were divided into two groups: with and without exposure to pesticides. The questionnaire was applied in hemodialysis clinics during treatment. Laboratory test values were collected from clinical records. Data were analyzed using descriptive statistics and association using the chi-square test. For laboratory test data, a comparison of means was performed using the unpaired Student's t-test between the groups. RESULTS The mean age of exposed participants was 58 years (±13.7; minimum = 23; maximum = 75) and that of non-exposed participants was 64 years old (±13.9; minimum = 35; maximum = 96). Of the 90 patients, 30% were exposed to pesticides. The mean exposure time was 6.7 ± 3.8 hours/day. There was a statistically significant association between the preparation of the mixture with pesticides and diabetes (p ≤ 0.048). There was no statistically significant difference between the results of laboratory tests in the exposed and non-exposed groups. CONCLUSION This study shows that pesticides can be triggering factors for chronic kidney disease (CKD); however, we must expand research in this field to prove the relationship between exposure to pesticides and CKD.

Abstract
To investigate the association between pesticide use and breast cancer. A hospital-based case-control study was conducted in Petrópolis city, Brazil. The study data were obtained through interviews, and the magnitude of the association between self-reported pesticide exposure and breast cancer was determined using unconditional logistic regression. A higher estimated risk for breast cancer was found in women exposed to pesticides for 10 or more years, where this association was not statistically significant after adjusting for potential confounders (OR = 1.40; 95% CI 0.85-2.49). A positive statistically significant association was found between breast cancer and higher educational level or previous use of hormone replacement therapy (HRT), whereas having had 2 or more pregnancies to term proved a protective factor. Further studies elucidating the contribution of pesticide exposure to the development of breast cancer are needed, given that current findings in the literature are conflicting.

Abstract
The constant exposure of rural workers to pesticides is a serious public health problem. Mancozeb (MZ) is a pesticide linked to hormonal, behavioral, genetic, and neurodegenerative effects, mainly related to oxidative stress. Vitamin D is a promising molecule that acts as a protector against brain aging. This study aimed to evaluate the neuroprotective role of vitamin D in adult male and female Wistar rats exposed to MZ. Animals received 40 mg/kg of MZ i.p. and 12.5 μg/kg or 25 μg/kg vitamin D by gavage, twice a week, for 6 weeks. The concentration of manganese had a significant increase in the hippocampus of both sexes and in the striatum of females, unlike zinc, which did not show a significant increase. MZ poisoning led to mitochondrial changes in brain tissues and promoted anxiogenic effects, especially in females. Alterations in antioxidant enzymes, mainly in the catalase activity were observed in intoxicated rats. Taken together, our results showed that exposure to MZ leads to the accumulation of manganese in brain tissues, and the behavior and metabolic/oxidative impairment were different between the sexes. Furthermore, the administration of Vitamin D was effective in preventing the damage caused by the pesticide.

Abstract
The abuse of chlorpyrifos (CHP), a commonly used organophosphorus pesticide, has caused many environmental pollution problems, especially its toxicological effects on non-target organisms. First, CHP enriched on the surface of plants enters ecosystem circulation along the food chain. Second, direct inflow of CHP into the water environment under the action of rainwater runoff inevitably causes toxicity to non-target organisms. Therefore, we used rats as a model to establish a CHP exposure toxicity model and studied the effects of CHP in rats. In addition, to alleviate and remove the injuries caused by residual chlorpyrifos in vivo, we explored the alleviation effect of chitosan oligosaccharide (COS) on CHP toxicity in rats by exploiting its high water solubility and natural biological activity. The results showed that CHP can induce the toxicological effects of intestinal antioxidant changes, inflammation, apoptosis, intestinal barrier damage, and metabolic dysfunction in rats, and COS has excellent removal and mitigation effects on the toxic damage caused by residual CHP in the environment. In summary, COS showed significant biological effects in removing and mitigating blood biochemistry, antioxidants, inflammation, apoptosis, gut barrier structure, and metabolic function changes induced by residual CHP in the environment.

Abstract
Weeds are major threats to the integrity of agricultural and natural environments due to their invasive and competing potential. Bioherbicides are substances based on natural compounds that are biodegradable and often have low residual effects. Plant species able to produce and release phytotoxic compounds may represent effective bioherbicide sources. Leaves of Quillaja lancifolia D.Don (formerly Q. brasiliensis (A.St.-Hil. & Tul.) Mart.) produce water-soluble specialized metabolites of the saponin class that could be evaluated for phytotoxic activity and potential as natural herbicides. This study was conducted to examine the impacts of Q. lancifolia total saponins aqueous extract (AE) at 4 and 10% (w/v) and of two combined reverse-phase chromatography purified saponin fractions (QB) at 1 and 2% (w/v) on morpho-physiological parameters of Lactuca sativa (lettuce) and Echinochloa crus-galli (barnyardgrass) in pre- and post-emergence bioassays. QB was only tested in pre-emergence assays. In pre-emergence bioassays, the germination rate and germination kinetics were determined. Post-emergence evaluations included effects on seedling morphology, root and shoot length, dry mass, and chlorophyll content. Osmotic potential and pH analyses ruled out roles for these factors in the observed responses. AE had a high inhibitory impact on the germination of both lettuce and barnyardgrass. QB at 1% and 2% (w/v) significantly decreased the growth of lettuce seedlings germinated in its presence by more than 10-fold. Phytotoxic effects on the post-emergence growth of lettuce, especially at the highest concentration tested of AE (10% w/v), was also observed. The presence of quillaic acid-based triterpene saponins in AE and QB was confirmed using different analytical methods. Therefore, both saponin-enriched fraction and aqueous extracts of Q. lancifolia inhibited tested plant growth and development. The water solubility of saponins and the availability of a sustainable source of these molecules from the leaves of cultivated young Q. lancifolia plants make them attractive candidates for use as bioherbicides.

Abstract
The use of pesticides to prevent and control pests also increases food production. Pesticides are widely used by contemporary farmers, especially in Brazil, where the economy is based on agriculture. The objective of this study was to evaluate the genotoxic potential of pesticide use in rural workers in Maringá, Paraná, Brazil. DNA damage in whole blood cells was measured by the comet assay, while the frequency of cell types, abnormalities, and nuclear damage was estimated using the buccal micronucleus cytome assay. Samples of buccal mucosa were collected from 50 male volunteers (27 not exposed to pesticides and 23 occupationally exposed to pesticides). Among them, 44 volunteered for blood sampling (24 unexposed and 20 exposed). In the comet assay, the exposed farmers had a higher damage index than non-exposed ones. There were also statistically significant differences between the groups in the buccal micronucleus cytome assay. Farmers exhibited an increase in basal cell numbers, and cytogenetic alterations, represented by condensed chromatin and karyolitic cells. Comparisons between cell morphologies and epidemiological factors indicated an increased number of condensed chromatin and karyolitic cells in individuals who were responsible for preparation and transportation of pesticides to agricultural machines. Thus, the participants in this study who were exposed to pesticides were more sensitive to genetic damage, and thereby, more susceptible to diseases resulting from such damage. These results demonstrated that health policies should be developed for pesticide-exposed farmers to better mitigate risks and damage to their health.

Abstract
The pyrethroid bifenthrin and the phenylpyrazole fipronil are widely employed insecticides, and their extensive use became an environmental issue. Therefore, this study evaluated their biodegradation employing bacterial strains of Bacillus species isolated from leaves of orange trees, aiming at new biocatalysts with high efficiency for use singly and in consortium. Experiments were performed in liquid culture medium at controlled temperature and stirring (32 °C, 130 rpm). After 5 days, residual quantification by HPLC-UV/Vis showed that Bacillus amyloliquefaciens RFD1C presented 93% biodegradation of fipronil (10.0 mg.L-1 initial concentration) and UPLC-HRMS analyses identified the metabolite fipronil sulfone. Moreover, Bacillus pseudomycoides 3RF2C showed a biodegradation of 88% bifenthrin (30.0 mg.L-1 initial concentration). A consortium composed of the 8 isolated strains biodegraded 81% fipronil and 51% bifenthrin, showing that this approach did not promote better results than the most efficient strains employed singly, although high rates of biodegradation were observed. In conclusion, bacteria of the Bacillus genus isolated from leaves of citrus biodegraded these pesticides widely applied to crops, showing the importance of the plant microbiome for degradation of toxic xenobiotics.

Abstract
Fipronil has been widely used in agriculture and forestry in Brazil to control several pests. However, this insecticide may be hazardous to non-target organisms, including stingless bees, which are essential pollinators of crops and natural environments. Here, we investigated the effect of 24-h acute oral exposure to LC50 of fipronil on the Malpighian tubules of the stingless bee Partamona helleri (Friese). Insecticide exposure decreases the respiration rate of forager bees, and the Malpighian tubules are severely affected, as shown by the epithelial architecture disorganization, loss of cytoplasmic content, degradation of the brush border, and nuclear pyknosis. In addition, fipronil ingestion increases the number of Malpighian cells positive for peroxidase, LC3, cleaved caspase-3, and JNK. However, Notch and ERK1/2-positive cells decrease in the exposed bees. These changes in the signaling proteins indicate an increase in oxidative stress, autophagy and apoptosis, and impairment of cell recovery. Overall, our results demonstrate the toxicological effects of fipronil on a stingless bee, which compromises the physiology of this important pollinator.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 848:157774. [PMID: 35932867 DOI: 10.1016/j.scitotenv.2022.157774] [Citation(s) in RCA: 33] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/28/2022] [Accepted: 07/29/2022] [Indexed: 05/06/2023]
Abstract
The increase and indiscriminate use of personal care products, food products, fertilizers, pesticides, and health products, among others, have resulted/are resulting in extensive environmental contamination. Most of these products contain traces of widespread chemicals, usually known as emerging pollutants (EPs) or pollutants of emerging concern (PEC). The Latin American (LA) region comprises 20 countries with different social and cultural aspects, with 81 % of the population living in urban areas. The LA region has some countries on the top list of users/consumers of EPs, from pesticides and fertilizers to personal care products. However, there is a gap in information related to the distribution of EPs in the environment of this region, with very few existing review texts exploring this issue. Therefore, this present paper advances this approach. An exhaustive literature review, with the selection of 176 documents, provided unique up-to-date information on the presence/distribution of 17 classes of legacy or emerging pollutants in different food and environmental matrices (soil, sediment, water, and air). The study shows that the wide distribution and recorded levels of these pollutants in the continental environment are potential risks to human health, mainly through food and drinking water ingestion. Polycyclic aromatic hydrocarbons are pollutants of deep public concern since they show carcinogenic properties. Several classes of pollutants, like endocrine disruptors, have caused harmful effects on humans and the environment. Besides that, pharmaceutical products and pesticides are compounds of high consumption worldwide, being environmental contamination a real and ongoing possibility. Finally, gaps and future research needs are deeply pointed out.

Abstract
OBJECTIVE To investigate the association between periconceptional environmental exposures and the occurrence of cleft lips and palates. METHODS This case-control study analyzed 150 mothers of children with cleft lips and palates living in the same city as 250 mothers whose children did not present with this malformation (controls). Environmental exposure data were gathered through a questionnaire (Latin American Collaborative Study of Congenital Malformations methodology). RESULTS Multivariate analysis revealed that monthly income below minimum wage, having another malformed child, other diseases in the first gestational trimester (urinary infection), use of pesticides in home gardens, and pesticide use in farms close to the home were risk factors associated with the malformation, whereas taking vitamins was a protective factor. CONCLUSION Maternal and paternal exposure to pesticides is associated with cleft lip and palate in Mato Grosso State, Brazil.

Abstract
The aim of this study was to carry out a pilot investigation, using a buccal micronucleus cytome assay, with the population of Vila Rural Água Viva (Francisco Beltrão, Paraná, Brazil), environmentally exposed to agrochemicals. The data shows statistically differences between the control group (not exposed) and the population of Vila Rural regarding the cytotoxicity and mutagenicity. There was no significant change between the average relative frequencies of these data whether divided between smokers and non-smokers, or practitioners of physical activities or not. It was also observed that age or time of exposure to agrochemicals did not show a linear relationship with the average relative frequencies of cytotoxicity and mutagenicity data. The work shows the presence of 2,4-D herbicide in water sample of community, then it is hoped that the results will assist in guiding the dangers to health and the environment from exposure to agrochemicals.

Impacts of soybean agriculture on the resistome of the Amazonian soil. Front Microbiol 2022; 13:948188.

Abstract
The soils of the Amazon are complex environments with different organisms cohabiting in continuous adaptation processes; this changes significantly when these environments are modified for the development of agricultural activities that alter the chemical, macro, and microbiological compositions. The metagenomic variations and the levels of the environmental impact of four different soil samples from the Amazon region were evaluated, emphasizing the resistome. Soil samples from the organic phase from the different forest, pasture, and transgenic soybean monocultures of 2–14 years old were collected in triplicate at each site. The samples were divided into two groups, and one group was pre-treated to obtain genetic material to perform sequencing for metagenomic analysis; another group carried out the chemical characterization of the soil, determining the pH, the content of cations, and heavy metals; these were carried out in addition to identifying with different databases the components of the microbiological communities, functional genes, antibiotic and biocide resistance genes. A greater diversity of antibiotic resistance genes was observed in the forest soil. In contrast, in monoculture soils, a large number of biocide resistance genes were evidenced, highlighting the diversity and abundance of crop soils, which showed better resistance to heavy metals than other compounds, with a possible dominance of resistance to iron due to the presence of the acn gene. For up to 600 different genes for resistance to antibiotics and 256 genes for biocides were identified, most of which were for heavy metals. The most prevalent was resistance to tetracycline, cephalosporin, penam, fluoroquinolone, chloramphenicol, carbapenem, macrolide, and aminoglycoside, providing evidence for the co-selection of these resistance genes in different soils. Furthermore, the influence of vegetation cover on the forest floor was notable as a protective factor against the impact of human contamination. Regarding chemical characterization, the presence of heavy metals, different stress response mechanisms in monoculture soils, and the abundance of mobile genetic elements in crop and pasture soils stand out. The elimination of the forest increases the diversity of genes for resistance to biocides, favoring the selection of genes for resistance to antibiotics in soils.

Abstract
Resumo Introdução: O uso de agrotóxicos pode desencadear doença renal. Objetivo: Descrever a exposição a agrotóxicos de pacientes com doença renal crônica em tratamento dialítico. Métodos: Pesquisa de campo, quantitativa e descritiva, com 90 portadores de doença renal crônica em tratamento dialítico em duas unidades de hemodiálise no estado de Santa Catarina, por meio da aplicação de um questionário estruturado. Os participantes foram divididos em dois grupos: sem e com exposição a agrotóxicos. O questionário foi aplicado nas clínicas de hemodiálise durante o tratamento. Foram coletados valores de exames laboratoriais dos prontuários clínicos. Os dados foram analisados pela estatística descritiva e associação pelo teste qui-quadrado. Para os dados dos exames laboratoriais, foi realizada comparação de médias pelo teste t de Student não pareado entre os grupos. Resultados: A idade média dos participantes expostos foi de 58 anos (±13,7; mínimo = 23; máximo = 75) e a dos não expostos, de 64 anos (±13,9; mínimo = 35; máximo = 96). Dos 90 pacientes, 30% foram expostos a agrotóxicos. O tempo médio de exposição foi de 6,7 ± 3,8 horas/dia. Houve associação estatística significativa entre o preparo da calda com agrotóxicos e a presença de diabetes (p ≤ 0,048). Não houve diferença estatística significativa entre os resultados dos exames laboratoriais do grupo exposto e do não exposto. Conclusão Esta pesquisa evidencia que os agrotóxicos podem ser fatores desencadeadores da doença renal crônica (DRC), entretanto sugere-se ampliar pesquisas na área que possam comprovar a relação entre exposição a agrotóxicos e DRC.

A review toward contaminants of emerging concern in Brazil: Occurrence, impact and their degradation by advanced oxidation process in aquatic matrices. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 836:155605.

Abstract
This work presents data regarding the occurrence and treatment of Contaminants of Emerging Concern (CECs) in Brazil in the past decade. The literature review (2011-2021) revealed the detection of 87 pharmaceutical drugs and personal care products, 58 pesticides, 8 hormones, 2 illicit drugs, caffeine and bisphenol A in distinct matrices (i.e.: wastewater, groundwater, sea water, rainwater, surface water, drinking water and hospital effluent). Concentrations of CECs varied from ng-μg L-1 depending on the location, compound and matrix. The inefficiency of conventional wastewater treatment methods on the removal of CECs and lack of basic sanitation in some regions in the country aggravates contamination of Brazilian aquatic environments and poses potential environmental and health risks. Advanced oxidation processes (AOPs) are pointed out as viable and efficient alternatives to degrade CECs and prevent environmental contamination. A total of 375 studies involving the use of AOPs in Brazilian aqueous matrices were published in the last decade. Fenton and photo-Fenton processes, photo-peroxidation, ozonation, electrochemical advanced oxidation and heterogeneous photocatalysis are some of the AOPs applied by Brazilian research groups. Although many works discuss the importance of applying these technologies for CECs removal in real treatment plants, most of these studies assess the treatment of distilled water or simulated effluent. Therefore, the conduction of studies applying AOPs in real matrices are critical to drive the implementation of these processes coupled to conventional water and wastewater treatment in real plants in order to prevent the contamination of environmental matrices by CECs in Brazil.

Abstract
Brazil is one of the world leaders in the agribusiness sector tending to directly influence a growing dependence on imported inputs, specifically synthetic agrochemicals. At the state level, in 2013, Tocantins stood out in first place in the ranking of agrochemical consumers, however, these products can cause several problems, such as poisoning to humans, environmental contamination, and increased resistance to phytopathogens. Biological control is an alternative to the use of agrochemicals towards eliminating pests naturally by using living organisms called Biological Control Agents (BCA). Currently, fungi of the Trichoderma genus are some of the most used organisms in biological pest control for their relevant characteristics that favor them in terms of survival in the environment, such as high capacity to adapt to ecological conditions, potential to colonize the rhizosphere of plants, mycoparasitism, production of volatile and non-volatile metabolites. In addition, it works on plant growth and productivity. In general, the use of Trichoderma favors the control of soil pathogens, such as Rhizoctonia, Pythium, Sclerotinia, and nematodes. Thus, this review aims to demonstrate the importance of using Trichoderma in biological control, as well as to present an overview and perspectives of research developed by respondents in the Brazilian Midwest region and Tocantins state.

Abstract
Sweet marjoram (Majorana hortensis) is an important aromatic herbal plant that has long been used and well managed in the traditional and general medical, pharmaceutical, food, cosmetic, and perfume industries. Thus, the increase in its productivity appears to be of great value since there is a large number of bioactive secondary metabolites as well as an increase in the demand in domestic or foreign markets. The purpose of this study is the possibility of promoting the sustainable development of marjoram in the framework of organic farming through gamma irradiation, chitosan and yeast. Field experiments were conducted in a factorial split-plot design with three iterations over two consecutive seasons (2019 and 2020). The main plot is an abiotic elicitor (15 Gy gamma irradiation), two biotic elicitors 500 ppm chitosan, 0.5% yeast, and a non-elicitor (as control), while in the sub-main plot, there were two organic fertilizers, water extract of moringa 20 g/m2 dry leaves, 20 g/m2 fulvic acid, and 20 g/m2 (NPK); the latter is a traditional agrochemical. Statistical analysis of all characteristics of production and quality of biomass and biologically active secondary metabolites revealed that the use of organic fertilizers helped in increasing the yield of marjoram, both qualitatively and quantitatively, and significantly outperformed the chemical fertilizer. The experiment enhances the comprehensive and integrated development of marjoram under organic cultivation and achieves a promising alternative to traditional cultivation without the use of microbicides and/or agrochemical pesticides.

Abstract
Rural children are exposed to several chemicals. This study evaluated the environmental co-exposure of rural children to cholinesterase inhibitor insecticides and metals/metalloids, and the resulting oxidative stress and DNA damage. Seventy-two children (5 to 16 years old) were studied at two different moments: period 1, when agrochemicals were less used, and period 2, when agrochemicals were extensively used in agriculture. Biomonitoring was performed by evaluating butyrylcholinesterase (BuChE) activity in serum; arsenic (As), chromium (Cr), lead (Pb), and nickel (Ni) levels in blood; malondialdehyde (MDA) in plasma; glutathione peroxidase (GSH-Px) and glutathione S-transferase (GST) activities in whole blood; non-protein thiol levels in erythrocytes; and micronuclei (MN) assay in exfoliated buccal cells. Cr and As levels were higher than the reference values in both periods, and Ni levels were higher than the reference values in period 2 alone. BuChE activity was inhibited in period 2 compared with period 1. In period 2, there was an increase in endogenous antioxidants and a decrease in MDA, probably demonstrating a compensatory mechanism as a response to increasing xenobiotics. Also in period 2, the MN frequency increased and BuChE and As were positively associated, suggesting co-exposure. On the other hand, in period 1, it was observed that Cr, Ni, and Pb blood levels were negatively associated with GSH-Px and GST, while MDA was positively associated with As levels. Our findings demonstrated an imbalance in endogenous antioxidants, contributing to genotoxicity and lipoperoxidation, probably in response to exposure to xenobiotics, especially carcinogenic elements (Cr, As, and Ni).

Abstract
The transgenic soy monoculture demands supplementation with pesticides. The aim of this study was to evaluate the individual and mixture effects of fipronil, glyphosate and imidacloprid in human HepG2 cells. Cytotoxicity was evaluated after 48-h incubations through MTT reduction and neutral red uptake assays. Free radicals production, mitochondrial membrane potential, DNA damage, and release of liver enzymes were also evaluated. Data obtained for individual agents were used to compute the additivity expectations for two mixtures of definite composition (one equipotent mixture, based in the EC50 values achieved in the MTT assay; the other one based in the acceptable daily intake of each pesticide), using the models of concentration addition and independent action. The EC50 values for fipronil, glyphosate and imidacloprid were 37.59, 41.13, and 663.66 mg/L, respectively. The mixtures of pesticides elicited significant synergistic effects (p < 0.05), which were greater than the expected by both addictive predictions. Decreased in mitochondrial membrane potential and increased in the transaminases enzymatic activities were observed. As they occur simultaneously, interactions between pesticides, even at non-effective single levels, can reverberate in significant deleterious effects, justifying the need for a more realistic approach in safety evaluations to better predict the effects to human health.

Somatic DNA Damage Response and Homologous Repair Gene Alterations and Its Association With Tumor Variant Burden in Breast Cancer Patients With Occupational Exposure to Pesticides.

Abstract
Homologous recombination is a crucial pathway that is specialized in repairing double-strand breaks; thus, alterations in genes of this pathway may lead to loss of genomic stability and cell growth suppression. Pesticide exposure potentially increases cancer risk through several mechanisms, such as the genotoxicity caused by chronic exposure, leading to gene alteration. To analyze this hypothesis, we investigated if breast cancer patients exposed to pesticides present a different mutational pattern in genes related to homologous recombination (BRCA1, BRCA2, PALB2, and RAD51D) and damage-response (TP53) concerning unexposed patients. We performed multiplex PCR-based assays and next-generation sequencing (NGS) of all coding regions and flanking splicing sites of BRCA1, BRCA2, PALB2, TP53, and RAD51D in 158 unpaired tumor samples from breast cancer patients on MiSeq (Illumina) platform. We found that exposed patients had tumors with more pathogenic and likely pathogenic variants than unexposed patients (p = 0.017). In general, tumors that harbored a pathogenic or likely pathogenic variant had a higher mutational burden (p < 0.001). We also observed that breast cancer patients exposed to pesticides had a higher mutational burden when diagnosed before 50 years old (p = 0.00978) and/or when carrying BRCA1 (p = 0.0138), BRCA2 (p = 0.0366), and/or PALB2 (p = 0.00058) variants, a result not found in the unexposed group. Our results show that pesticide exposure impacts the tumor mutational landscape and could be associated with the carcinogenesis process, therapy response, and disease progression. Further studies should increase the observation period in exposed patients to better evaluate the impact of these findings.

Abstract
OBJECTIVE To estimate the prevalence of occupational and environmental exposure according to sociodemographic factors in cancer patients treated at reference hospitals in the state of Mato Grosso, Brazil. METHODS This is a cross-sectional study on cancer patients aged 18 years or older. The prevalence of exposure to pesticides, asbestos, lead, heavy metals, formaldehyde, benzene, exposure to industrial dust, and handling of other chemical substances were calculated according to sex, age group, and level of education. RESULTS A total of 1,012 patients were interviewed (55.0% women, 45.6% aged 60 years or older, and 56.8% had less than five years of formal education). Pesticides (22.8%), industrial dust (10.7%), and benzene (10.1%) were the most frequent exposures. Occupational and environmental exposure was higher in men for all evaluated exposures, except for formaldehyde, which was higher in women. Exposure to pesticides, industrial dust, benzene, asbestos, and heavy metals increased with age and were more frequent among those with lower level of education. CONCLUSION Approximately one in five cancer patients treated at reference hospitals in Mato Grosso reported having been exposed to pesticides, and one in ten were exposed to industrial dust and benzene, with greater exposure among men, older individuals, and those with lower level of education.

Abstract
OBJECTIVE To describe the methodological and operational aspects of the "Project for surveillance of cancer and its associated factors: population-based and hospital-based registry" (VIGICAN), in the state of Mato Grosso (MT), Brazil. METHODS VIGICAN was divided into two projects: a university extension one, which updated the data from the Population-based Cancer Registry (PBCR) of MT in the 2008-2016 period; and a research project, which collected primary data, through individual interviews and analysis of medical records of people with a diagnosis of cancer, aged 18 years or older, treated at reference hospitals for oncology. To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, health status and behavior, and environmental exposure. RESULTS In the 2008-2016 period, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the PBCR Cuiabá and PBCR Interior. After validation procedures, 50 thousand incident cases were elected. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in small cities of the state, and 1.4% in other states. Preliminary data showed that the majority were women (55.0%) and younger than 60 years of age (54.3%). Among the interviewees, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%), and 32.7% lived nearby crops. CONCLUSION The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.

Abstract
OBJECTIVE To analyze the trend of standardized cancer mortality rate in the state of Mato Grosso according to health regions, from 2000 to 2015. METHODS Ecological time series study with data on deaths by cancer from the Mortality Information System. The rates were standardized using direct method and calculated by year and health regions. The annual percentage changes (APC) and respective confidence interval (95%CI) were obtained through simple linear regression. Thematic maps were built to show the spatial distribution of rates. RESULTS There were 28,525 deaths by cancer registered in Mato Grosso, with the main types being lung, prostate, stomach, breast and liver cancer. The highest mortality rates were found in regions Médio Norte, Baixada Cuiabana and Sul Mato-Grossense. From 2000 to 2015, an upward trend was seen in the mortality rate by cancer in Mato Grosso (APC=0.81%; 95%CI 0.38-1.26), and in four health regions, Garças Araguaia (APC=2.27%; 95%CI 1.46-3.08), Sul Mato-Grossense (APC=1.12%; 95%CI 0.28-1.97), Teles Pires (APC=1.93%; 95%CI 0,11-3,74) and Vale dos Arinos (APC=2.61%; 95%CI 1.10-4.70), while the other regions remained stable. CONCLUSION In the state of Mato Grosso and in the four health regions, cancer mortality rate showed a growing trend. The results point to the need to consider regional differences when thinking about actions for cancer prevention, control and assistance.

Abstract
OBJECTIVE To estimate the mortality trend and to analyze the potential years of life lost (PYLL) due to leukemias and lymphomas in Brazil and Mato Grosso, from 2001 to 2019. METHODS Time-series study on deaths from leukemias and lymphomas with data obtained from the Mortality Information System. Trends were calculated by age group by the Joinpoint regression method, using calendar year as regressor variable, estimated annual percentage change (APC) and mean annual percentage change, considering 95% confidence intervals. PYLL rates were collected from the Cancer Mortality Atlas. RESULTS In Brazil, the mortality rate trend remained stable for both diseases in the period: leukemias (APC=0.2; 95%CI 0.0-0.3) and lymphomas (APC=0.2; 95%CI 0.4-0.1). In Mato Grosso state, the rate for leukemias was also stable (APC=0.3; 95%CI 1.0-1.6). For lymphomas, the trend was ascendant (APC=2.3; 95%CI 0.5-4.2), but descending among people younger than 59 years. For leukemias, PYLL rates were 64 and 65/100,000 in Brazil and Mato Grosso, respectively. For lymphomas, 27 and 22/100,000, respectively, with the highest rates found among males. CONCLUSION The behavior of mortality rates from leukemia and lymphoma in Mato Grosso was different from that observed nationally, with an upward trend for lymphomas and no differences between age groups for both diseases. PYLL rates for leukemias were similar, while for lymphomas they were higher among men and lower in Mato Grosso when compared to Brazil.

Abstract
The evaluation of genotoxicity in workers exposed to different toxic agents is very important, especially considering the association between these exposures in a chronic context and DNA damage. Assessing biomarkers of exposure and, when possible, early biomarkers of effect, contributes to elucidating the potential toxic mechanisms involved in genotoxicity and its contribution to chronic non-communicable diseases. In Brazil, the biggest country in South America, workers are exposed to hazardous physical and chemical agents. Considering that these exposures occur, in most cases, throughout the worker's whole life, this is an important public health concern in Brazil. Therefore, this systematic review aims to analyze occupational exposure to chemical and physical agents and the association with DNA damage in studies carried out in Brazil from 1980 to 2021. A systematic and comprehensive literature search was performed in different databases based on occupational exposure to chemical and physical agents and DNA damage. Only full articles on studies that investigated experimental evidence on occupational exposure in Brazil and assessed DNA damage were included, amounting to 89 articles. Five main occupational exposure groups were identified: pesticides (36%), organic solvents (20%), dust and particles (16%), metals (11%), and ionizing radiation (6%). Another group called "others" included studies (11%) that did not fall into these main groups. It was found that comet assay and micronucleus tests are the most adopted methods to detect DNA damage. Occupational exposures were most associated with DNA damage. However, further improvements in study design would be needed to better characterize the association between biomonitoring and DNA damage, particularly to account for confounding factors.

Abstract
The objective is to verify the effects of pesticides on the health of farmers in the southern region of Brazil, as well as the possible symptoms and cases of intoxication. This study has a quantitative, descriptive and exploratory approach, carried out in 12 agricultural locations in the municipality of Serra Catarinense. This research was approved by the research ethics committee and was applied through a structured questionnaire to 79 farmers who grow grains in the conventional cultivation system. The pesticide most used by farmers was glyphosate, followed by acephate. Of the individuals, 21.5% reported that they had suffered poisoning by pesticides by the respiratory route (58.8%). In addition, 28% had three symptoms of intoxication, demonstrating possible probable cases of intoxication. And 41% of workers reported headaches as a predominant symptom in applications with the use of pesticides, followed by dizziness/vertigo (16%). Farmers who use PPE during the preparation of the pesticide spray are neither chronic diseases (p<0.003) nor psychological problems (p<0.000). All four individuals who had cancer, all also eat while applying pesticides (p<0.049). The exposure to pesticides causes changes in the organism of those exposed, using them more vulnerable to health problems.

Abstract
Recent evidence suggests that pesticides may play a role in chronic kidney disease. However, little is known about associations with acute kidney failure (AKF). We investigated trends in AKF and pesticide expenditures and associations with agricultural work in two Brazilian regions with intense use of pesticides, in the south and midwest. Using death certificate data, we investigated trends in AKF mortality (1980-2014). We used joinpoint regression to calculate annual percent changes in AKF mortality rates by urban/rural status and, in rural municipalities, by tertiles of per capita pesticide expenditures. We then compared AKF mortality in farmers and population controls from 2006 to 2014 using logistic regression to estimate odds ratios and 95% confidence intervals adjusted by age, sex, region, education, and race. AKF mortality increased in both regions regardless of urban/rural status; trends were steeper from the mid-1990s to 2000s, and in rural municipalities, they were higher by tertiles of pesticide expenditures. Agricultural workers were more likely to die from AKF than from other causes, especially at younger ages, among females, and in the southern municipalities. We observed increasing AKF mortality in rural areas with greater pesticide expenditures and an association of AKF mortality with agricultural work, especially among younger workers.

Abstract
Every year, Brazil intensifies its activity in agriculture and, as a result, it has become one of the biggest consumers of pesticides in the world. The high rate of these substances raises environmental and human health concerns. Therefore, we collected papers from PubMed, Scopus, Scielo, and Web of Science databases, from 2015 to 2021. After a blind selection using the software Rayyan QCRI by two authors, 51 studies were included. Researchers from the South and the Southeast Brazilian regions contributed to most publications, from areas that concentrate agricultural commodity complexes. Among the pesticides described in the studies, insecticides, herbicides, and fungicides were the most frequent. The articles reported multiple toxic effects, particularly in rural workers. The results obtained can be used to direct policies to reduce the use of pesticides, and to protect the health of the population.

Rodrigues LCC, Fortini RM, C. R. Neves M. Impacts of the use of biological pest control on the technical efficiency of the Brazilian agricultural sector. INTERNATIONAL JOURNAL OF ENVIRONMENTAL SCIENCE AND TECHNOLOGY : IJEST 2022; 20:1-16. [PMID: 35284000 PMCID: PMC8902737 DOI: 10.1007/s13762-022-04032-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 02/01/2022] [Accepted: 02/10/2022] [Indexed: 06/14/2023]
Abstract
This paper aimed to assess the impact of the intensive use of biological control on the technical efficiency of the Brazilian agricultural sector. The study also considered the influence of factors such as technical assistance, rural financing, and membership in cooperatives or class entities on efficiency measures. It was estimated stochastic production frontiers for regions intensively using and not using biological control, considering potential selection bias. Results demonstrate that areas with intensive use of biological pest management have a 0.863 technical efficiency score, while this score is 0.823 for nonintensive areas. This means that the intensive regions would be closer to their efficiency frontiers. Additionally, technical assistance and membership in cooperative or class entities increase efficiency by 6 and 2.5%, respectively. It can be concluded that the intensive adoption of biological control can raise the productive performance of the Brazilian agricultural sector. Therefore, it must be highlighted the importance of formulating joint policies (e.g., credit+rural extension) for the adoption of biological control to be a feasible option to promote the sustainable development of the Brazilian agricultural sector.

Abstract
Studies assessing the toxicity of glyphosate and 2,4-dichlorophenoxyacetic acid mixture are scarce. The aim of this study was to evaluate the cytotoxicity and genotoxicity of the mixture of these herbicides using Allium cepa. Roots were exposed to glyphosate (1.56 and 11.66 mg mL-1), 2,4-D (0.28 and 17.5 mg mL-1) and mixture for 24 h, based on the average concentration applied in the field and the acute reference dose (ARfD) established in Brazil. Both isolated and associated herbicides induced a significative decrease in mitotic index (MI) (P < 0.0001) in all tested concentrations. Regarding the genotoxicity results, 2,4-D and the mixture showed, at concentrations applied in the field, a significative increase of chromosomal anomalies (CA) index compared to control (P < 0.0001) and glyphosate (P = 0.024 and P = 0.0002, respectively). All tested groups from the ARfD showed a significative difference compared to the control group (P < 0.0001), as well as glyphosate and 2,4-D isolated compared to the mixture (P = 0.0005 and P < 0.0001, respectively). The most observed CA were apoptotic bodies, giant cells, and nuclear erosions. We emphasize the need for further studies assessing the toxicity of these herbicides' mixture due to the distinct effects caused in different organisms.

Abstract
Free-living birds play an important role as bioindicators in natural environments. In this study, we used the micronucleus test and nuclear erythrocyte abnormalities to investigate the difference in the genotoxic damage frequency between animals in agricultural areas (soybean planting) in relation to the conserved area. It was also discussed the bird's eating habits, which are important for ecotoxicological analysis. The results point to a difference between the insectivorous, granivorous, and omnivorous guilds. The omnivore Gnorimopsar chopi was the species that most exhibited micronucleus frequency in the protected area. In the agricultural area, the animals did not differ in the genotoxic damage frequency. In the comparison between common species in both environments, G. chopi from the agricultural area showed a micronuclei frequency almost three times higher in relation to specimens collected in the conserved area. Based on these results, this study adds to the efforts of using the micronucleus test as a simple and accessible tool for biomonitoring the wild fauna. It can be concluded that the passerine, G. chopi, due to its higher genotoxic damage frequency may be a strong candidate to indicate environmental health.

Abstract
RESUMO A imensa sociobiodiversidade do Cerrado brasileiro pode ser compreendida a partir dos modos de vida construídos pelo amplo leque de povos e comunidades tradicionais em suas relações com o bioma, do qual são guardiãs. Nas últimas décadas, projetos de desenvolvimento promovem ali acelerado avanço do agronegócio, expropriando terras, privatizando águas, contaminando o ambiente e ameaçando ou inviabilizando modos de vida tradicionais. Neste artigo, parte-se da percepção de mulheres de Campos Lindos/TO, sobre as consequências trazidas às suas vidas e saúde por empresas produtoras de soja. Em seguida, questiona-se a constituição do Cerrado como zona de sacrifício do desenvolvimento brasileiro, ao concentrar terras para a produção de 75% de quatro commodities agrícolas, desmatar mais de 50% da vegetação nativa, exaurir aquíferos e levar rios à morte, contaminar o ambiente com 73,5% dos agrotóxicos consumidos no País, trazendo implicações para o processo saúde-doença (como intoxicações agudas, malformações, cânceres, desnutrição, adoecimento mental) e para outros biomas do Brasil e países da América do Sul. Conclui-se perscrutando alternativas na perspectiva dos comuns, do decrescimento, dos direitos da natureza e do bem viver, instigando reflexões da saúde coletiva e da agroecologia sobre a contribuição dos saberes e fazeres tradicionais à saúde e à emancipação humana.

Abstract
RESUMO: Objetivos: Estimar a tendência de mortalidade e analisar os anos potenciais de vida perdidos (APVP) por leucemias e linfomas no Brasil e em Mato Grosso, entre os anos de 2001 e 2019. Métodos: Estudo de série temporal de óbitos por leucemias e linfomas obtidos do Sistema de Informação sobre Mortalidade. As tendências foram calculadas por faixa etária pelo método de regressão joinpoint, usando ano calendário como variável regressora, e estimaram-se a variação percentual anual (APC) e a variação percentual média anual, considerando intervalos de confiança de 95% (IC95%). As taxas de APVP foram coletadas do Atlas de Mortalidade por Câncer. Resultados: No Brasil, a tendência da taxa de mortalidade apresentou estabilidade para ambos os agravos, leucemias (APC=0,2; IC95% 0,0–0,3) e linfomas (APC=0,2; IC95% 0,4–0,1). No estado, a taxa por leucemias também apontou estabilidade (APC=0,3; IC95% 1,0–1,6). Para os linfomas, a tendência foi de aumento (APC=2,3; IC95% 0,5–4,2), contudo tendência decrescente foi observada entre aqueles com menos de 59 anos. Para leucemias, as taxas de APVP foram de 64 e 65/100 mil no Brasil e em Mato Grosso, respectivamente. Para linfomas, esses valores foram de 27 e 22/100 mil, respectivamente, sendo as maiores taxas encontradas no sexo masculino. Conclusão: As taxas de mortalidade por leucemias e linfomas em Mato Grosso apresentam comportamento diferente do observado nacionalmente, com tendência crescente para linfomas e sem diferenças entre as faixas etárias, para ambos os agravos. As taxas de APVP por leucemias foram semelhantes, no entanto para os linfomas foram maiores entre os homens e menores para o estado, quando comparadas com as do Brasil.

Abstract
RESUMO Este ensaio se propõe à análise crítica do agronegócio, buscando construir um modelo teórico compreensivo, tendo como referência o conceito de biopoder de Foucault. Pretende ainda contribuir para as discussões de alternativas sustentáveis e de combate às ações que promovem e flexibilizam o uso de agrotóxicos. Argumenta-se que o agronegócio, apesar de ter tido sua imagem construída por discursos que ressaltam sua eficiência e produtividade, impõe barreiras que impedem a garantia da segurança alimentar e nutricional. Pelo uso intensivo de agrotóxicos, também não disponibiliza alimentos seguros e de qualidade, ao mesmo tempo que impacta o meio ambiente e compromete a saúde da população, somado aos seus impactos políticos, econômicos, sociais e culturais. A análise sob a ótica do biopoder destaca que a atuação das indústrias agrícola, agroquímica e de alimentos, enquanto normatizadoras e geradoras de consumo, desconsideram princípios morais e éticos, infringem direitos humanos e a autonomia dos sujeitos. Paralelamente, propõe-se que, por meio da educação popular e a educação alimentar e nutricional, consegue-se, em longo prazo, construir sujeitos e coletividades autônomos e críticos, capazes de transformar as estruturas de poder vigentes e de agir em prol de políticas públicas que fomentem práticas justas, saudáveis, sustentáveis e éticas.

Abstract
RESUMO Desde 2013, Pernambuco desenvolve o Plano de Vigilância em Saúde de Populações Expostas aos Agrotóxicos, cujas estratégias incluem o cadastro de trabalhadores rurais aplicadores de agrotóxicos, realizado pelas Equipes de Saúde da Família. Com o objetivo de descrever as características do uso de agrotóxicos, o perfil dos trabalhadores atuantes com essa prática e as condições de saúde que os constitui foram analisados, no período de janeiro de 2015 a agosto de 2019. Realizou-se estudo transversal, descritivo, em que as variáveis selecionadas foram organizadas em quatro grupos: 1) Características sociodemográficas; 2) Condições de saúde; 3) Características do uso do agrotóxico; e 4) Princípios ativos mais utilizados e suas categorias de análise. Os resultados evidenciam que, entre os aplicadores de agrotóxicos, encontram-se pessoas menores de idade, idosas, analfabetas, sem treinamento e sem Equipamento de Proteção Individual; a utilização de agrotóxicos proibidos e classificados como extremamente tóxicos; e a comercialização de agrotóxicos sem o controle adequado. Além de apontar caminhos mediante a análise do cenário apresentado, esta pesquisa indica a urgência de articulação intersetorial para a efetividade da promoção e proteção da saúde dessa população.

Abstract
RESUMO: Objetivo: Descrever os aspectos metodológicos e operacionais do projeto “Vigilância do câncer e seus fatores associados: registro de base populacional e hospitalar” (VIGICAN), em Mato Grosso (MT). Métodos: O VIGICAN desdobrou-se em dois projetos: um de extensão, que atualizou os dados dos Registros de Câncer de Base Populacional (RCBP) de Mato Grosso no período de 2008 a 2016; e um de pesquisa, que coletou dados primários por meio de entrevistas individuais e análise de prontuários de pessoas com diagnóstico de câncer, com 18 anos ou mais, atendidas em hospitais de referência para oncologia. Para analisar os fatores associados ao câncer, foram coletadas as seguintes variáveis: socioeconômicas e demográficas, suporte social, situação e comportamentos de saúde e exposição ambiental. Resultados: No período de 2008 a 2016, foram notificados nos RCBP Cuiabá e Interior, aproximadamente, 100 mil casos de câncer (incidentes e prevalentes). Após os procedimentos de validação, foram eleitos 50 mil casos incidentes. A pesquisa entrevistou 1.012 pacientes, sendo 38,2% residentes nos municípios de Cuiabá e Várzea Grande, 60,4% no interior do Estado e 1,4% em outros Estados. Os dados preliminares revelaram que a maioria era do sexo feminino (55,0%) e tinha menos de 60 anos (54,3%). Entre os entrevistados, 7,2% relataram fumar tabaco, 15,5% consumiam bebidas alcoólicas (15,5%) e 32,7% moravam próximo a lavouras. Conclusão: O desenvolvimento desses projetos permitiu a integração do ensino com os serviços de saúde e possibilitará o reconhecimento das especificidades e dos diferentes cenários de exposição ao câncer, bem como fatores associados a ele, no território mato-grossense.
