Effect of Pesticide Exposure over DNA Damage in Farmers from Los Reyes, Michoacan in Mexico. TOXICS 2023; 11:toxics11020122. [PMID: 36850997 PMCID: PMC9966867 DOI: 10.3390/toxics11020122] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/19/2023] [Accepted: 01/21/2023] [Indexed: 05/23/2023]
Abstract
In the municipality of Los Reyes, Michoacán, in Mexico, several economic activities coexist; however, the most relevant is agriculture. It stands out as an agro-industrial center and commercial enclave in the region, suitable for the cultivation of sugar cane; however, currently fruit growing takes first place with blackberry, raspberry and blueberry, followed by avocado, peach, strawberry and other crops. A large quantity and variety of pesticides are applied to crops, consequently the population is at constant risk. This study aimed to evaluate whether pesticides are a factor in genetic damage to agricultural workers from Los Reyes, Michoacán, using alkaline comet assay. Fifty-nine residents participated (41 workers and 18 controls). Results included confounding factors (alcohol consumption, smoking habit, gender, age, BMI, etc.) indicated a non-significant statistical difference between two groups, with higher DNA damage values in workers that was higher than the values expected in a normal healthy unexposed population. It seems that the control measures, safe handling of pesticides and quality standards, required by the producers so that their products can be exported, have resulted in less damage, despite workers' activity, but higher damage than the reference values still requires regular surveillance of those exposed. The use of protective equipment or measures can reduce the risk of damage, so it is also necessary to promote their service and comply with labor regulations for agricultural workers.

Abstract
In this investigation, the concentration of some organochlorine pesticides (OCPs) was monitored in the Karkheh River and the risk assessment of exposure to these pesticides residue through the water supply system was calculated. The mean concentrations of Lindane, Heptachlor, Chlordane, Dieldrin, Endrin, DDT were 0.135, 0.123, 0.077, 0.081, 0.076, 0.01 µg/L, respectively. The average risk of Lindane, Heptachlor, Chlordane, Dieldrin, DDT, and Endrin for adults was 1.2 E-6, 1.1E-6, 7E-7, 7.6E-7, 9E-8, 7E-7 or non-carcinogenic risks to adults decreased in Dieldrin > Chlordane > Heptachlor > Endrine > DDT > lindane. The hazard index for all organochlorine pesticides was less than 1. These results did not raise concerns about the health of people exposed to studied pesticides. Total concentrations of all OCPs in the Karkheh River were below guidelines for individual pesticides. The hazard quotient showed that the consumption of treated water from the Susangard drinking water treatment plant has no non-cancerous effects. The HI was less than 1 that indicating the risk of exposure to a mixture of OCPs was not significant. Developing policies to reduce the use of pesticides and the use of suitable management practices could be implemented to lower the pesticide levels in the Karkheh River.

Abstract
The purpose of this study was to investigate the effect of body mass index on DNA damage of lymphocytes in obese patients without carbohydrate metabolism disorder in the Kazakh population. Research design is based on a single-stage descriptive study. The sample included 239 patients aged 18-60 years. Among the participants, people with chronic decompensated diseases, with bad habits (smokers, drug users, drinkers) were excluded. Special attention was paid to the exclusion of diabetes mellitus to exclude the effect of hyperglycemia on DNA damage when forming the sample according to WHO criteria. The following were estimated: the diameter of the breaks (Foci dia, µm), the average number of γ-H2AX (n) foci detected per cell. The study of DNA damage of blood lymphocytes in individuals of the Kazakh population showed high rates of DSB with a BMI over 40 kg/m2. The number of breaks per cell in women is significantly higher than in men (p = 0.004). The median test revealed a significant difference in the number of DSBs between different age groups (χ2 = 10.39, p = 0.0155). Obesity is now gaining momentum, so the study of the effect of body mass index on lymphocyte DNA damage in obese patients without impaired carbohydrate metabolism gives valuable results in the treatment of this disease.

Abstract
(1) Objective: Greenhouse workers are considered a special occupational group who are exposed to more toxic and harmful substances than ordinary farmers. The health problem of this group is a public health problem that warrants attention. Taking greenhouse workers in Ningxia, China, as the research sample, this study analyzed the health risk to practitioners posed by the greenhouse working environment. (2) Method: To analyze the relationship between pesticide exposure and the health of greenhouse workers, the genetic matching method was used to exclude the influence of covariates on the results. (3) Results: The results showed a statistical significance regarding the prevalence of cardiovascular diseases (CVD), skeletal muscle system diseases (SMSD) and digestive diseases between the different exposure groups. Researching the disease symptoms found that different levels of exposure to pesticides in greenhouses could cause multisystem and multisymptom discomfort. In addition to some irritant symptoms such as eye itching, itching, and sneezing, there were also differences in terms of the frequency of discomfort such as back pain, a decline in sleep quality, memory loss, joint pain, swelling and weakness, upper abdominal pain and flatulence, in the different exposure groups. (4) Conclusion: Different levels of exposure to pesticides in greenhouses may be one of the risk factors for practitioners to suffer from various systemic diseases, affecting their health and work efficiency. This hazard is manifested not only in some acute irritant symptoms but also in chronic diseases due to long-term exposure.

Abstract
Soybean farmers are exposed to various types of pesticides that contain in their formulations a combination of chemicals with genotoxic and mutagenic potential. Therefore, the objective of this paper was to evaluate the genetic damages caused by this pesticide exposure to soybean producers in the state of Mato Grosso (Brazil), regarding biochemical, genetic polymorphic and in silico analyses. A total of 148 individuals were evaluated, 76 of which were occupationally exposed and 72 were not exposed at all. The buccal micronucleus cytome assay (BMCyt) detected in the exposed group an increase on DNA damage and cell death. No inhibition of butyrylcholinesterase (BchE) was observed within the exposed group. The detection of inorganic elements was made through the particle-induced X-ray emission technique (PIXE), which revealed higher concentrations of Bromine (Br), Rubidium (Rb) and Lead (Pb) in rural workers. A molecular model using in silico analysis suggests how metal ions can cause both DNA damage and apoptosis in the exposed cells. Analysis of the compared effect of X-ray Repair Cross-complement Protein 1 (XRCC1) and Paraoxonase 1 (PON1) genotypes in the groups demonstrated an increase of binucleated cells (exposed group) and nuclear bud (non-exposed group) in individuals with the XRCC1 Trip/- and PON1 Arg/- genes. There was no significant difference in the telomere (TL) mean value in the exposed group in contrast to the non-exposed group. Our results showed that soybean producers showed genotoxic effect and cell death, which may have been induced by exposure to complex mixtures of agrochemicals and fertilizers. In addition, XRCC1 Arg/Arg could, in some respects, provide protection to individuals.

Cytotoxic and Genotoxic Effects of Pesticide Exposure in Male Coffee Farmworkers of the Jarabacoa Region, Dominican Republic. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15081641. [PMID: 30081446 PMCID: PMC6121533 DOI: 10.3390/ijerph15081641] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2018] [Revised: 07/31/2018] [Accepted: 08/02/2018] [Indexed: 12/16/2022]
Abstract
Intensive agrochemical use in coffee production in the Global South has been documented. The aim of this study was to investigate cytotoxic and genotoxic effects of pesticide exposure in male farmworkers in the Dominican Republic comparing conventional farming using pesticides to organic farming. Furthermore, feasibility of the buccal micronucleus cytome assay (BMCA) for field studies under difficult local conditions was tested. In a cross-sectional field study, pesticide exposed (sprayers) and non-exposed male workers on coffee plantations were interviewed about exposure history, and pesticide application practices. Buccal cells were sampled, and BMCA was applied to assess potential effects on cell integrity. In total, 38 pesticide-exposed and 33 non-exposed workers participated. Eighty-four and 87%, respectively, of the pesticide-exposed respondents did not use masks or gloves at all. All biomarkers from the BMCA were significantly more frequent among exposed workers—odds ratio for micronucleated cells: 3.1 (95% confidence interval: 1.3–7.4) or karyolysis: 1.3 (1.1–1.5). Buccal cells as sensitive markers of toxic oral or respiratory exposures proved feasible for challenging field studies. Our findings indicate that the impact of pesticide use is not restricted to acute effects on health and wellbeing, but also points to long-term health risks. Therefore, occupational safety measures including training and protective clothing are needed, as well as encouragement towards minimal application of pesticides and more widespread use of organic farming.

Abstract
Monitoring exposure to xenobiotics by biomarker analyses, such as a micronucleus assay, is extremely important for the precocious detection and prevention of diseases, such as oral cancer. The aim of this study was to evaluate genotoxic effects in rural workers who were exposed to cigarette smoke and/or pesticides and to identify possible classification patterns in the exposure groups. The sample included 120 participants of both sexes aged between 18 and 39, who were divided into the following four groups: control group (CG), smoking group (SG), pesticide group (PG), and smoking + pesticide group (SPG). Their oral mucosa cells were stained with Giemsa for cytogenetic analysis. The total numbers of nuclear abnormalities (CG = 27.16 ± 14.32, SG = 118.23 ± 74.78, PG = 184.23 ± 52.31, and SPG = 191.53 ± 66.94) and micronuclei (CG = 1.46 ± 1.40, SG = 12.20 ± 10.79, PG = 21.60 ± 8.24, and SPG = 20.26 ± 12.76) were higher (p < 0.05) in the three exposed groups compared to the GC. In this study, we considered several different classification algorithms (the artificial neural network, K-nearest neighbors, support vector machine, and optimum path forest). All of the algorithms displayed good classification (accuracy > 80%) when using dataset2 (without the redundant exposure type SPG). It is clear that the data form a robust pattern and that classifiers could be successfully trained on small datasets from the exposure groups. In conclusion, exposing agricultural workers to pesticides and/or tobacco had genotoxic potential, but concomitant exposure to xenobiotics did not lead to additive or potentiating effects.

Abstract
The use of pesticides in agricultural production originates residues in the environment where they are applied. Pesticide aerial application is a frequent source of exposure to pesticides by persons dedicated to agricultural practices and those living in neighboring communities of sprayed fields. The aim of the study was to assess the genotoxic effects of pesticides in workers occupationally exposed to these chemicals during their aerial application to agricultural fields of Sinaloa, Mexico. The study involved 30 pilots of airplanes used to apply pesticides via aerial application and 30 unexposed controls. Damage was evaluated through the micronucleus assay and by other nuclear abnormalities in epithelial cells of oral mucosa. The highest frequency ratios (FR) equal to 269.5 corresponded to binucleated cells followed by 54.2, corresponding to cells with pyknotic nuclei, 45.2 of cells with chromatin condensation, 3.7 of cells with broken-egg, 3.6 of cells with micronucleus, and 2.0 of karyolytic cells. Age, worked time, smoking, and alcohol consumption did not have significant influence on nuclear abnormalities in the pilots studied. Pesticide exposure was the main factor for nuclear abnormality results and DNA damage. Marked genotoxic damage was developed even in younger pilots with 2 years of short working period, caused by their daily occupational exposure to pesticides.

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.
