Abstract
This review examined the mutagenicity and genotoxicity associated with exposure to outdoor air pollutants in Brazil. A search was performed on the Web of Science database using a combination of keywords that resulted in 134 articles. After applying exclusion criteria, a total of 75 articles were obtained. The articles were classified into three categories: (1) studies with plants and animals, (2) in vitro studies, and (3) human biomonitoring. The investigations were conducted in 11 of 27 Brazilian states with the highest prevalence in the southeast and south regions. Only 5 investigations focused on the effects of burning biomass on the quality of outdoor air. Plants, especially Tradescantia pallida, were the main air pollution biomonitoring tool. When available, a significant association between levels of air pollutants and genetic damage was described. Among the in vitro studies, Salmonella/microsome is the most used test to evaluate mutagenesis of outdoor air in Brazil (n = 26). Human biomonitoring studies were the least frequent category (n = 18). Most of the investigations utilized micronucleus bioassay, in oral mucosa cells (n = 15) and lymphocytes (n = 5), and the comet assay (n = 6). The analysis in this study points to the existence of gaps in genotoxicity studies and our findings indicate that future studies need to address the variety of potential sources of pollution existing in Brazil. In addition to extent of the impacts, consideration should be given to the enormous Brazilian biodiversity, as well as the determination of the role of socioeconomic inequality of the population in the observed outcomes.

Smoot J, Padilla S, Farraj AK. The utility of alternative models in particulate matter air pollution toxicology. Curr Res Toxicol 2022; 3:100077. [PMID: 35676914 PMCID: PMC9168130 DOI: 10.1016/j.crtox.2022.100077] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 05/04/2022] [Accepted: 05/25/2022] [Indexed: 11/29/2022] Open
Abstract
Countless unique particulate matter (PM) samples with limited or no toxicity information. Alternative in vivo models offer greater throughput than traditional mammalian models. Use of zebrafish, fruit flies, and nematodes in PM toxicology lacks systematic review. Their utility in PM toxicity and mechanistic research and as screening tools is reviewed.
Exposure to particulate matter (PM) air pollution increases risk of adverse human health effects. As more attention is brought to bear on the problem of PM, traditional mammalian in vivo models struggle to keep up with the risk assessment challenges posed by the countless number of unique PM samples across air sheds with limited or no toxicity information. This review examines the utility of three higher throughput, alternative, in vivo animal models in PM toxicity research: Danio rerio (zebrafish), Caenorhabditis elegans (nematode), and Drosophila melanogaster (fruit fly). These model organisms vary in basic biology, ease of handling, methods of exposure to PM, number and types of available assays, and the degree to which they mirror human biology and responsiveness, among other differences. The use of these models in PM research dates back over a decade, with assessments of the toxicity of various PM sources including traffic-related combustion emissions, wildland fire smoke, and coal fly ash. This article reviews the use of these alternative model organisms in PM toxicity studies, their biology, the various assays developed, endpoints measured, their strengths and limitations, as well as their potential role in PM toxicity assessment and mechanistic research going forward.

Abstract
The main environmental problem in urban areas, especially in Brazil, is the discharge of untreated sewage. The in vivo Drosophila melanogaster Somatic Mutation and Recombination Test (SMART) was used to assess the genotoxicity of surface waters from three different sites in the Tocantins River, Brazil. The in silico approach was used to search for known and predicted interactions between environmental chemicals found in our samples and Drosophila and human proteins. The genotoxicity tests were performed in standard (ST) and high bioactivation (HB) crosses with samples collected at two periods, the rainy and dry seasons. Mutant spot frequencies found in treatments with unprocessed water from the test sites were compared with the frequencies observed in negative controls. The collection points were represented as sites A, B and C along Tocantins River. Sites A and B are located in Porto Nacional City, whereas site C is located in Palmas City. Considering the rainy season collection, positive responses in the ST cross were observed for sites A and C (89.47% and 85% of recombination, respectively) and in the HB cross for sites A, B and C (88.24%, 84.21% and 82.35% of recombination, respectively). The positive results in the dry season were restricted to sites A and B (88.89% and 85.71% of recombination, respectively) in the HB cross. In accordance with in vivo and in silico results, we hypothesize that ribosomal proteins (RPs) in fruit fly and humans are depleted in cells exposed to heavy metal causing DNA damage and chromosome instability, increasing homologous recombination.

Abstract
This study evaluated the genotoxic potential of atmospheric pollution associated with urbanization using the model organism Drosophila melanogaster and the Comet assay with hemolymph cells. Larvae were exposed to atmospheric compounds in an urban and a rural area in the municipality of Vitória de Santo Antão, Pernambuco, Brazil, for 6 days (from the embryo stage to the third larval stage) in April 2015 and April 2017. The results were compared to a negative environmental control group exposed to a preserved area (Catimbau National Park) and to a negative control exposed to the laboratory room conditions. The Comet assay demonstrated significant genetic damage in the organisms exposed to the urban area compared with those exposed to the rural area and negative control groups. The evidences were supported by particulate matter analysis showing higher photopeaks of chemical elements such as aluminum, silicon, sulfur, potassium, calcium, titanium, and iron, associated to road dust fraction in urban environment. Once again, the results confirm D. melanogaster an ideal bioindicator organism to monitor genotoxic hazard associated with atmospheric pollution.

In vivo and in vitro genotoxicity assessment of 2-methylisoborneol, causal agent of earthy-musty taste and odor in water. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2014; 100:282-286.

Abstract
The water eutrophication process by phosphorus and nitrogen allows cyanobacteria blooms which promote, among other effects, the generation and release of the metabolite 2-methylisoborneol (2-MIB) in the environment. This substance has been shown to be recalcitrant to conventional water treatment, degrading water quality. Considering the limited number of studies on the biological effects of 2-MIB in eukaryotic organisms, the present study assessed the genotoxicity of 2-MIB using the in vitro comet assay and cytokinesis block-micronucleus (CBMN-Cytome) assay on Chinese Hamster Ovary (CHO) cells and the in vivo Drosophila melanogaster Somatic Mutation and Recombination Test (SMART). The results showed that 2-MIB (125, 250 and 500 µg/mL) was unable to induce gene and chromosome mutations or events associated with mitotic recombination in the SMART. Similarly, four different concentrations (7.5, 15, 30 and 60 µg/mL) of 2-MIB did not induce increments in frequencies of micronuclei, nuclear buds, and nucleoplasmatic bridges in the CBMN-Cytome assay. In the comet assay, the positive results were restricted to the highest dose, 60 µg/mL of 2-MIB. The results obtained may help evaluate the genotoxic profile of extracellular algal products.

Abstract
Terminalia actinophylla has been used for anti-diarrheic and haemostatic purposes in Brazil. The fly spot data obtained after exposure of marker-heterozygous Drosophila melanogaster larvae to T. actinophylla ethanolic extract (TAE) in the standard (ST) and high bioactivation (HB) crosses revealed that TAE did not induce any statistically significant increment in any spot categories. Differences between the two crosses are related to cytochrome P450 (CYPs) levels. In this sense, our data pointed out the absence of TAE-direct and indirect mutagenic and recombinagenic action in the Somatic Mutation and Recombination Test (SMART). When the anti-genotoxicity of TAE was analyzed, neither mitomycin C (MMC) nor ethylmethanesulfonate (EMS) genotoxicity was modified by the post-exposure to TAE, which suggests that TAE has no effect on the mechanisms involved in the processing of the lesions induced by both genotoxins. In the mwh/flr(3) genotype, co-treatment with TAE may lead to a significant protection against the genotoxicity of MMC and a weak but significant effect in the toxic genetic action of EMS. The overall findings suggested that the favorable modulations by TAE could be, at least in part, due to its antioxidative potential.

Abstract
Ambient particulate matter (PM) has been reported to be associated with increased respiratory, cardiovascular, and malignant lung diseases. The aim of the present study was to investigate the variability of the DNA-damage induced by thoracic particles (PM( 10)) sampled in different locations and seasons (2006) in Dalian, China, in human hepatoma G2 (HepG2) cells. Significant differences in percentage of tail DNA induced by the extractable organic matter of PM(10) were revealed between summer and winter seasons and among monitoring sites in single cell gel electrophoresis (SCGE) assay. The percentage of tail DNA in HepG2 cells significantly increased in a dose-dependent manner after exposure to 7.5 and 30 μg/mL extractable organic matter of PM(10) for 1 hour. In order to clarify the underlying mechanisms, we evaluated the level of reactive oxygen species (ROS) production with the 2, 7-dichloro-fluorescein diacetate (DCFH-DA) assay. Significantly increased level of ROS was observed in HepG2 cells at higher concentrations (15 and 30 μg/mL). Significantly increased levels of 8-hydroxydeoxyguanosine (8-OHdG) were also shown in HepG2 cells. In this study, the accumulation of nuclear factor kappa B (NF-κB) p65 protein induced by the extractable organic matter of PM(10) was detected by western blotting in HepG2 cells, and the protein expression of NF-κB p65 significantly increased after the treatment with 30 μg/mL extractable organic matter of PM(10) for 24 hours. These results indicate that the extractable organic matter of PM(10) causes DNA strand breaks in HepG2 cells, and significant differences in percentage of tail DNA in dependence on locality and season are revealed. The extractable organic matter of PM(10) exerts DNA damage effects in HepG2 cells, probably through oxidative DNA damage induced by intracellular ROS, increase of 8-OHdG formation, and protein expression of NF-κB p65.

Abstract
This study characterizes the likely interaction of surface water and sediment samples with DNA to quantitatively and qualitatively establish their mutagenic and/or recombinagenic activity. Samples were collected at 5 different sites within the area of Araçá Stream and 2 different sites within the Sinos River mouth and Garças Stream in the municipality of Canoas, RS, Brazil. The area is impacted by untreated urban discharges (sites 1-7), agricultural pesticides (sites 5 and 7), hospital waste (site 3), animal dejects (site 5), small industries (sites 4, 5 and 6) and vehicular discharges (sites 2, 4, 5 and 6). The wing Somatic Mutation and Recombination Test (SMART) in Drosophila melanogaster was used. The test detects simultaneously mutations and recombination induced by the activity of genotoxins of direct and indirect action. All the samples displayed a massive recombinagenic response, but no mutagenic activity was detected in any of the evaluated samples. This study was done in D. melanogaster with unprocessed water and sediment samples attributing a massive and exclusive recombinagenic action associated to the induction of homologous recombination--a genetic phenomenon involved in the loss of heterozygosity.

Abstract
Few studies on the genotoxicity of halonitromethanes (HNMs) have been done. This limited information on their potential genotoxic risk gives special relevance to the collection of new data on their potential genotoxic activity. In the present study we have analyzed the genotoxicity of two HNMs namely bromonitromethane (BNM) and trichloronitromethane (TCNM) in the in vivo wing somatic mutation and recombination test in Drosophila, also known as the wing-spot assay. This test is based on the principle that loss of heterozygosis and the corresponding expression of the suitable recessive markers, multiple wing hairs (mwh) and flare-3 (flr(3)), can lead to the formation of mutant clones in larval cells, which are then expressed as spots on the wings of adult flies. BNM and TCNM were supplied to third instar larvae (72+/-4 h-old) at concentrations ranging from 0.1 to 2 mM. The results showed that none of the three categories of mutant spots recorded (small, large, and twin) increased significantly by the treatments, independently of the dose supplied, indicating that the selected HNMs exhibit a lack of genotoxic activity in the wing-spot assay of Drosophila melanogaster. These results contribute to increase the genotoxicity database on the HNMs.

Abstract
Few studies on the genotoxicity of mercury compounds have been carried out in Drosophila melanogaster, most of them focused in the effects on germinal cells, whereas studies in somatic cells are scarce. In the present study we have analyzed for the first time the genotoxic activity of mercury (II) chloride (MC) and methyl mercury (II) chloride (MMC) in the in vivo wing somatic mutation and recombination test in Drosophila, also known as the wing spot assay. This test is based on the principle that loss of heterozygosis and the corresponding expression of the suitable recessive markers, multiple wing hairs (mwh) and flare-3 (flr(3)), can lead to the formation of mutant clones in larval cells, which are then expressed as spots on the wings of adult flies. The mercury compounds were supplied to third instar larvae (72+/-2h old) at concentrations ranging from 1 to 50 microM for mercury chloride (MC) and from 0.5 to 5 microM for methyl mercury chloride (MMC). Both mercury compounds showed high toxicity; however, MMC was more toxic than MC. The results showed that none of the three categories of mutant spots recorded (small, large, and twin) increased significantly by the treatments, independently of the dose supplied, indicating that the mercury compounds tested exhibit a lack of genotoxic activity in the wing spot assay of D. melanogaster. These results contribute to increase the genotoxicity database on the in vivo evaluation of mercury compounds in Drosophila.
