Abstract
The variation in light within the environment triggers morphophysiological changes in plants and can lead to distinct responses in sun-exposed or shaded plants to glyphosate. The response of Urochloa genotypes subjected to desiccation with 2160, 1622.4, 1080, 524.4, 273.6, and 0.0 g ha-1 of glyphosate was evaluated in full sun and shade conditions. Cayana grass, mulato II grass, and sabiá grass - hybrids recently launched on the market, in addition to palisade grass and congo grass were evaluated. Under full sun, we achieved control of congo grass using 1080 g ha-1 of glyphosate, while the other grasses required 2160 g ha-1. In the low-light environment, sabiá grass was effectively controlled with 524.4 g ha-1 of glyphosate, but the other grasses needed 273.6 g ha-1. In shading, compared to full sun, the savings with glyphosate were 75 and 76% for the control of congo grass and sabiá grass, respectively, and 87% for palisade grass, mulato II grass and cayana grass. Increasing glyphosate doses leads to a decline in the quantum efficiency of photosystem II and in the electron transport rate, especially in the shade. Urochloa genotypes are more sensitive to glyphosate in the shade, which must be considered when determining the herbicide dose.

Impacts of soybean agriculture on the resistome of the Amazonian soil. Front Microbiol 2022; 13:948188. [PMID: 36160259 PMCID: PMC9500545 DOI: 10.3389/fmicb.2022.948188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 08/16/2022] [Indexed: 11/15/2022] Open
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
OBJECTIVE To estimate the potential years of life lost (PYLL) to cancer in the State of Mato Grosso, from 2000 to 2019, stratified by sex, according to age groups and cancer types. METHODS It is a quantitative study with an ecological approach developed from secondary data, using the PYLL and its derivatives. RESULTS In the period analyzed, deaths from cancer in Mato Grosso resulted in 680,338 PYLL before the age of 80, with a variation of 82.5%. Of this total, 52.7% were assigned to males. The rate of the PYLL for cancer before the age of 60 was 70.9% in males, and 80.1% among women. The rates of PYLL increased in the period and showed slightly higher values in males. In the analysis according to age group, the rates of PYLL were also higher in males, except between the ages of 30 and 49. Lung cancers and lymphomas/leukemias resulted in greater losses of PYLL among men and female specific cancers (breast, cervical and uterine, and ovarian cancer) accounted for 36.26% of the PYLL among women, with variability per age groups. CONCLUSION In Mato Grosso, the PYLL indicator for cancer presented unfavorable evolution between 2000 and 2019, with greater damage for males and for the younger population. Leukemias, lymphomas, and lung and breast cancers were the main causes for the PYLL.

Abstract
RESUMO: Objetivo: Estimar os anos potenciais de vida perdidos por câncer no estado de Mato Grosso, no período de 2000 a 2019, estratificando os dados por sexo, segundo faixas etárias e tipos de câncer. Métodos: Trata-se de um estudo quantitativo, com abordagem ecológica a partir de dados secundários, utilizando-se o indicador anos potenciais de vida perdidos e seus derivados. Resultados: No período analisado, as mortes por câncer em Mato Grosso resultaram em 680.338 anos potenciais de vida perdidos antes dos 80 anos, com variação de 82,5%. Desse total, 52,7% foram atribuídos ao sexo masculino. O peso dos anos potenciais de vida perdidos por câncer antes dos 60 anos foi de 70,9% no sexo masculino e 80,1% entre as mulheres. As taxas de anos potenciais de vida perdidos aumentaram no período estudado e apresentaram valores ligeiramente mais elevados entre os homens. Na análise segundo faixas etárias, as taxas de anos potenciais de vida perdidos também foram maiores entre os homens, exceto entre 30 e 49 anos. Os cânceres de pulmão e linfomas/leucemias resultaram em maiores perdas de anos potenciais de vida entre os homens, e os cânceres de especificidade feminina (mama, colo e corpo do útero e ovário) responderam por 36,26% dos anos potenciais de vida perdidos entre as mulheres, com variabilidade por faixas etárias. Conclusão: Em Mato Grosso, o indicador anos potenciais de vida perdidos por câncer apresentou evolução desfavorável entre 2000 e 2019, com maior prejuízo para o sexo masculino e para a população mais jovem. As leucemias, linfomas e cânceres de pulmão e mama foram os principais responsáveis pelos anos potenciais de vida perdidos.

Abstract
RESUMO O processo de produção do agronegócio químico-dependente é um dos maiores geradores de riscos, desastres socioambientais e sanitários de caráter pandêmico. Ele atua na determinação social da saúde-doença-danos ambientais, levando a situações críticas, riscos e vulnerabilidades, exploração humana, intoxicações agudas e crônicas e degradações ecológicas como efeitos de suas formas danosas de estabelecer inter-relações entre produção-ambiente-sociedade. O setor tem contribuído diretamente para a crise ecológica e sanitária globalizada ao dar origem a sindemias, insegurança alimentar, contaminação das águas, alimentos além de produzir doenças infecciosas novas e/ou reemergentes. Neste ensaio crítico, com base nos estudos do Núcleo de Estudos Ambientais e Saúde do Trabalhador da Universidade Federal de Mato Grosso, demonstram-se diferentes elementos ameaçadores, destrutivos, degradantes e violadores do direito à saúde dos trabalhadores e ambiental nos principais elos da cadeia produtiva do agronegócio. Em seguida, utilizando também análises de documentos públicos, normativas do Estado e dados de sistemas de vigilância em saúde, evidenciam-se os processos de contaminação de alimentos e água decorrentes dos agrotóxicos, bem como apresenta-se uma crítica às tendências políticas que giram em torno do agronegócio. Por fim, destaca-se a necessidade premente de uma transição agroecológica enquanto resposta às doenças e às sindemias do agronegócio.

Abstract
Bacillus thuringiensis insecticides have been considered safe, being an alternative to the use of synthetic insecticides. However, studies have shown the effects of Bt Cry toxins on various organs, compromising their functions. The objective of this work was to test whether the administration of biological insecticides based on B. thuringiensis in pregnant rats will cause histopathological changes in the liver and kidneys, as well as in the levels of toxicity biomarkers, of their puppies in adulthood. Twenty rats, 90 days old, were used, divided into four groups: GC - Pregnant rats, GX - Pregnant rats that received XenTari®, GDi - Pregnant rats that received Dipel® and GDe - Pregnant rats that received deltamethrin. Insecticides were administered by gavage at a dosage of 1 mg/100 g/day (GX and GDi), and 2 mg/Kg/day (GDe) during pregnancy and lactation. In the animals of the groups whose matrices received the insecticides, there was a reduction in the levels of the biomarkers of toxicity alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea and creatinine, about the control group. The biological insecticides promoted histopathological changes in the liver, with the presence of portal vein, centrilobular and sinusoidal capillaries congestion, and in the kidney, presence of cortical congestion and reduction of the subcapsular space. Histochemical evaluation in the liver demonstrated a significant reduction in glycogen in the groups that received insecticides when compared to the control group, whereas for collagen fibers in both the liver and the kidneys, no differences were observed between the experimental groups. The morphometry of the liver revealed a significant reduction in the lobular parenchyma and an increase in the non-lobular parenchyma, and in the kidney, there was a reduction in the diameter and volume of the glomerulus and Bowman's capsule of the animals whose matrices received both biological and synthetic insecticides. Thus, it is concluded that the biological insecticides XenTari® and Dipel® in sublethal doses in pregnant rats promote changes in the liver and kidney of the offspring similar to the insecticide deltamethrin, which extend into adulthood.

Abstract
Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) Middle East Asia Minor 1 is one of the most important pests of the common bean, due to its potential of causing direct and indirect damage. This study aimed to evaluate 78 bean genotypes to verify the occurrence of resistance of antixenosis type against B. tabaci. Initially, multiple-choice trials were performed to evaluate the oviposition preference and nymphs' establishment at 3 and 15 days after infestation. Subsequently, 21 bean genotypes were selected, and a no-choice test was conducted. Colorimetric analyses were performed to establish correlations between leaf color and insect establishment. In multiple-choice trial, the genotypes BRS Ametista, BRS Estilo, BRS Esplendor, SCS 204 Predileto, BRS Notável, IPR Eldorado, CHIB 06, IPR Quero-Quero, Iapar 81, CHIP 338, IPR Garça, Arcelina 4, SCS 202 Guará, IAC Esperança, H96102-1-1-1-52, CHIP 348, Carioca Comum, CHIP 300, IAC Carioca Eté, IAC Ybaté, and Tybatã were the least used for oviposition and nymph establishment, demonstrating antixenosis or antibiosis. In the no-choice trial, most genotypes were less attractive to whitefly, and the genotypes CHIB 06, IPR Garça, CHIP 300, and IAC Esperança had less oviposition. The most attractive genotypes presented high luminosity and more intense green and yellow colors, indicating positive correlation. Therefore, the genotypes BRS Ametista, SCS 204 Predileto, BRS Estilo, IPR Eldorado, SCS-202 Guará, Carioca Comum, Arcelina 4, CHIP 348, and IAC Esperança showed the highest resistance stability in the no-choice trial, and they are promising sources of antixenotic factors for use in breeding programs to obtain whitefly-resistant common bean lines.

Abstract
RESUMO O uso de agrotóxicos na agricultura brasileira é um problema de saúde pública, dadas as contaminações no ambiente, em alimentos e as intoxicações resultantes do uso dessas substâncias. O objetivo deste artigo é investigar a distribuição espacial das áreas plantadas de lavouras e as taxas de mortalidade de alguns tipos de câncer: mama, colo do útero e próstata. Escolheram-se quatro estados brasileiros que possuem grande produção de commodities agrícolas a serem estudadas. Trata-se de um estudo ecológico de análise espacial conduzido com dados e informações do Sistema de Informação sobre Mortalidade (SIM) do Ministério da Saúde, por meio do qual elaboraram-se taxas de mortalidade para os referidos tipos de câncer, cujos óbitos tenham ocorrido entre 1996 e 2016. Há indícios de que existe correspondência entre as áreas de maior estimativa de uso de agrotóxicos Disruptores Endócrinos e o aumento das taxas de mortalidade pelos diferentes tipos de câncer.

Abstract
Resumo Objetiva-se analisar se características sociodemográficas, capacitação técnica e percepção de risco estão relacionados com a saúde ocupacional de agricultores expostos a agrotóxicos. Foi feito estudo transversal e observacional com 113 agricultores, selecionados aleatoriamente, no município de Cerro Largo, RS. Realizadas entrevistas nas propriedades rurais e investigadas questões referentes a caracterização sociodemográfica, capacitação técnica para uso de agrotóxicos, percepção de risco à saúde e sintomas de intoxicação aguda ou crônica. Houve prevalência do sexo masculino, baixo nível de escolaridade, idade entre 51 e 76 anos, que trabalham em pequenas propriedades rurais. A maioria dos agricultores afirmou ter recebido treinamento para uso de agrotóxicos por empresas que os comercializam. Os agricultores reconhecem os riscos da exposição ocupacional a agrotóxicos e relataram sintomas de intoxicação. A partir dos relatos, observa-se a não existência de capacitação técnica por parte de órgãos públicos no município, apesar de constatada a necessidade e queixas de sintomas de intoxicação por agrotóxicos. Evidencia-se a urgente demanda por capacitação técnica sobre uso seguro de agrotóxicos e informações sobre os efeitos nocivos destes à saúde, na medida em que conhecimento é uma forma de empoderamento.

Abstract
Background: Breast cancer is a serious public health problem and is the second most prevalent cancer type in the world. The purpose of this article is to evaluate the association between pesticide use and breast cancer in a region of intense agribusiness activity in the state of Mato Grosso, Brazil. Methods: A case-control study was conducted on women living in the city of Rondonópolis, in the south of Mato Grosso state. There were 85 cases of women with confirmed breast cancer and 266 controls who were randomly selected from primary health care users. Bivariate and stratified analyses were performed. Multiple logistic regression was then performed, keeping in the final model the factors with a significance level lower than or equal to 0.05 or considered important according to apriori biological criteria. Results: In the final model, living near cropland with pesticides (OR: 2.37; CI: 95% 1.78–3.16) and women aged over 50 years who experienced early menarche (OR: 2.08; CI: 95% 1.06–4.12) had a higher risk of developing breast cancer compared to control subjects. Conclusion: This study highlights the importance of exposure to pesticides as an environmental risk factor for the development of breast cancer among women.

Abstract
OBJECTIVE To analyze trends in pesticide poisoning incidence rates in Brazilian regions, according to sex and circumstances of poisoning, between 2001 and 2014. METHOD Ecological time-series study, with data from the national Notifiable Diseases Information System (SINAN). The incidence rates were calculated by dividing the number of confirmed new cases of pesticide poisoning by the total resident population in the same period and location. Both Polynomial regression analysis and Mann-Whitney and Kruskal-Wallis tests were performed. When significant differences were found, these tests were followed by the Bonferroni penalty, in order to identify the difference more precisely. RESULTS In Brazil, 80,069 notified poisoning cases were recorded from 2001 to 2014. There was a steadily increasing growth of pesticide poisoning in this population, whose growth trend was 0,377 for 100,000 inhabitants per year. The highest incidence of poisoning occurred in the South and Midest Regions. Regarding sex, no significant differences were found (p < 0,347), and attempted suicide was the most significant circumstance of poisoning (p < 0,001). CONCLUSION The incidence of pesticide poisoning in Brazil has been continuously increasing in the twenty-first century.

Abstract
The objective of this study was to evaluate pesticide poisonings in the southern region of Brazil between years 1999 and 2014. Data were collected from the database Sinitox. Intoxications and deaths were evaluated according to the distribution by gender (female and male), age group (≤14, 15-59 and ≥60 years), area of occurrence (urban and rural), circumstance (accident, occupational and suicide attempt) and evolution of the cases over time (cure, unconfirmed cure, death and sequelae). In the evaluated period, 21,305 cases of intoxication were registered. The results show that males between the ages of 15 and 59 years are more affected; and there is a greater representativeness in the urban area. These results are related to the application of agrochemicals being carried out by individuals between 15 and 59 years of age. The great correlation of urban area possibly occurs in function of the air currents brought from the field and as a result, population has been more affected and the consumption of contaminated food. It was observed that women handling pesticides more cautiously, in this way the accidents with male gender are more frequent, however, many women use the product intentionally to provoke suicide.

Abstract
The toxicity of Roundup Original® (GLY), a glyphosate-based herbicide widely used in crops in Mato Grosso state, was determined in hybrid fish jundiara or pintado da Amazônia. The 96 h-LC50 of GLY was 13.57 mg L-1. Moreover, exposure to sublethal concentrations of GLY (0, 0.37, 0.75, 2.25, 4.5, 7.5 mg L-1) has not altered the survival rate (100% for all treatments). In fish liver, protein carbonyl (PC) levels as well as glutathione-S-transferase (GST) activity, reduced glutathione (GSH), and ascorbic acid (ASA) contents increased when compared to control group. Superoxide dismutase (SOD) activity was reduced and catalase (CAT) has not changed. PC content has grown in muscle and brain, and thiobarbituric acid-reactive species (TBARS) levels also increased in muscle, but in the brain, they remained unaltered. Acetylcholinesterase (AChE) activity reduced in muscle but increased in brain when compared to control group. Our results suggest that short-term exposure to GLY induced alterations in the oxidative stress biomarkers in fish and can be interfering with their survival in natural environment; besides, these findings may be considered of high ecotoxicological relevance.

Abstract
ABSTRACT Brycon falcatus is one of the most highly consumed species of fish within the region in the Teles Pires basin, and has great commercial importance in sport and professional artisanal fishing. The objective of this study was to analyze the presence and concentration of total mercury (THg) in the muscle, liver and gills of B. falcatus, and calculate the risk to human health of THg contamination from ingestion of the fish. THg concentrations were similar in the liver (0.076 mg kg-1) and muscle (0.052 mg kg-1), and higher than in the gills (0.009 mg kg-1). The levels of HgT present in B. falcatus tissues did not influence weight gain and nutritional status. Based on the condition factor, weight and length ratio and hepatosomatic index, it seems that the concentrations of THg did not influence the health and well-being of B. falcatus collected in the Teles Pires River basin. THg concentrations in the muscle of B. falcatus are below the limit recommended by the World Health Organization for people who consume until 250 g of fish per week. The risk of deleterious effects on human health may exist if there is a greater consumption of B. falcatus such as 340 g/day, that is the mean of fish consumption by indigenous and riverine.

Abstract
Resumo O uso de agrotóxicos na agricultura brasileira é um problema de saúde pública, dadas as contaminações no ambiente, em alimentos e as intoxicações na saúde humana. Objetivou-se apresentar a distribuição espacial da área plantada de lavouras, consumo de agrotóxicos e agravos à saúde relacionados, como estratégia de Vigilância em Saúde. Obteve-se dados de área plantada de 21 culturas predominantes, indicadores de consumo de agrotóxicos por hectare para cada cultura e agravos à saúde. Espacializou-se o consumo de agrotóxicos nos municípios brasileiros e correlacionou-se às incidências de intoxicações por agrotóxicos: aguda, subaguda e crônica. Constatou-se predomínio dos cultivos de soja, milho e cana, que juntos corresponderam a 76% da área plantada no Brasil em 2015. Pulverizou-se 899 milhões de litros de agrotóxicos nessas lavouras, com Mato Grosso, Paraná e Rio Grande Sul tendo utilizado as maiores quantidades. Os agravos à saúde apresentaram correlações positivas e significativas com o uso de agrotóxicos. A estratégia metodológica possibilitou identificar municípios prioritários para a Vigilância em Saúde e o desenvolvimento de ações intersetoriais de prevenção e mitigação dos impactos dos agrotóxicos na saúde e ambiente.

Abstract
Background Most fetal defects are associated with genetic and environmental causes, among them, exposure of pregnant women to intensive pesticide use. Agribusiness is the economic basis of the state of Mato Grosso, the largest consumer of pesticides of all Brazilian states. The objective of this study was to investigate the association between past parental exposure to pesticides and the occurrence of congenital malformations in children in Mato Grosso, Brazil. Methods This hospital-based case–control study was conducted in Cuiabá, the capital of Mato Grosso, from March to October 2011. Data was collected in all public, private, and health plan referral hospitals that provide care for pregnant women in the state of Mato Grosso and were situated in Cuiabá. Cases were children under 5 years of age with congenital malformations classified in Chapter XVIII of the International Classification of Diseases-10 and controls were children within the same age range, without congenital malformations, treated at the same hospitals. Malformation-related data was obtained from the patients’ medical records. Socioeconomic data and information about parental exposure to pesticides were obtained in an interview with the mother using a standardized questionnaire. We conducted multivariate logistic regression to assess the relation between parent report of past pesticide use and congenital malformations. We also assessed effect modification to verify whether low maternal education level modified the association between exposure and our outcome. Results We observed positive effect modification of the association of paternal past exposure to pesticide and congenital malformation in the offspring by maternal education for mothers with low educational level (OR = 8.40, 95 % CI 2.17–32.52), father’s work related to farming (OR = 4.65, 95 % CI 1.03–20.98) and paternal past exposure to pesticides (OR = 4.15, 95 % CI 1.24–13.66). Conclusion These findings provide further evidence that paternal exposure to pesticides, especially when associated with a low maternal education level, may be related to higher rates of fetal malformation in Mato Grosso, Brazil.

Abstract
The neotropical stink brown bug, Euschistus heros (F.) (Hemiptera: Pentatomidae), is an insect pest to soybean crops in Mato Grosso State, Brazil. In this region, synthetic insecticides are frequently used for insect control. An alternative to the indiscriminate use of insecticides is the biological control with parasitoids. Thus, the objective of this study was to conduct the survey of parasitoids that use E. heros adults as hosts. Random samples were conducted during the harvests of 2009/10 and 2010/11 in two farms that produce soybean (conventional system) in Tangará da Serra, Mato Grosso State, Brazil. The total number of collected E. heros was: 297 (Field 1) and 293 (Field 2) in 2009/10 and 295 (Field 1) and 376 (Field 2) in 2010/11. Of these, 1.50 (Field 1) and 13.99% (Field 2) were parasitized in 2009/10 and 8.47 (Field 1) and 7.45% (Field 2) in 2010/11. The parasitoids found were Hexacladia smithii Ashmead (Hymenoptera: Encyrtidae) in both fields. This is the first record of parasitism in E. heros adults in the state of Mato Grosso, Brazil.

Abstract
Risk factors involved in the etiology of prostate cancer are not well known. The objective of this study was to explore correlations among variables relating to agricultural production, the use of health services, food consumption and socio-demographic characteristics and prostate cancer mortality rates in Brazilian states. Univariate analysis of spatial data for investigation of global spatial autocorrelation in prostate cancer mortality rates in Brazilian states between 2005 and 2009 was conducted. Using bivariate analysis, the correlation between socio-demographic indicators, agricultural production data, variables related to the use of health services dietary intake variables and prostate cancer mortality rates were examined. The production of soybeans and corn were positively correlated with prostate cancer mortality. In multiple linear spatial regression, the variables that showed an association with mortality rates from prostate cancer were tons of soybeans produced (p = 0.030), proportion of the population aged 80 and over (p < 0.001) and consumption of beverages (p < 0.001). A positive correlation between tons of soybeans planted and mortality from prostate cancer was identifed, suggesting the possible existence of an association between exposure to pesticides and prostate cancer.

Abstract
Como estratégia da vigilância em saúde do trabalhador, população e ambiente, foram analisadas as quantidades, os tipos e a toxicidade de agrotóxicos usados por hectare nas lavouras mato-grossenses para servir de apoio às vigilâncias dos municípios brasileiros. O Brasil cultivou 95 milhões de hectares de lavouras em 2012 e Mato Grosso foi o maior consumidor de agrotóxicos. Utilizaram-se dados do banco informatizado do Instituto de Defesa Agropecuário que registra nas notas fiscais de venda e local de uso e os dados dos receituários agronômicos. Os resultados mostraram que em média um hectare de soja consumiu 12 litros de agrotóxicos, o de milho 6 litros, o de cana 4,8 litros e o de algodão 24 litros. Verificaram-se também os tipos e classes toxicológicas usadas por hectare de cada lavoura. Também, verificou-se, através de uma matriz de produção agropecuária e consumo de pesticidas, que alguns agravos à saúde estão correlacionados com as regiões mais produtoras. A partir dos dados de consumo de agrotóxicos, pela produção agrícola e da toxicidade desses venenos, podem-se inferir seus agravos e danos nos municípios brasileiros e estabelecer estratégias de prevenção e de vigilância à saúde dos trabalhadores, do ambiente e das populações expostas.
