Abstract
The use of pesticide use has been linked to the higher production of reactive oxygen species, resulting in oxidative stress, which in turn can cause genomic instability. A marker for instability is the copy number variation of the mitochondrial genome (mtDNAcn), which has been found to be altered in diverse human diseases, including tumors. This research aimed to examine the variation of mtDNAcn in individuals occupationally exposed to pesticides. Real-time PCR assays were conducted on 154 individuals (78 exposed and 76 non-exposed). Pesticide-exposed ndividuals exhibited a significant reduction in mtDNAcn (1.11 ± 0.37mtDNAcn/genome) compared to non-exposed individuals (1.30 ± 0.33mtDNAcn/genome; p = 0.001). The multivariate analysis indicated that individuals who reported using haloxyfop and copper sulfate demonstrated an increase (β = 0.200, p = 0.053) and a decrease (β=-0.2, p = 0.021), respectively, in mtDNAcn. In conclusion, our findings suggest that chronic exposure to pesticides results in changes in mtDNAcn.
期刊介绍:
International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
