Effects of Soil pH on the Biodegradation of Chlorpyrifos and Isolation of a Chlorpyrifos-Degrading Bacterium [PDF]
Applied and Environmental Microbiology, 2003 ABSTRACT We examined the role of microorganisms in the degradation of the organophosphate insecticide chlorpyrifos in soils from the United Kingdom and Australia. The kinetics of degradation in five United Kingdom soils varying in pH from 4.7 to 8.4 suggested that dissipation of chlorpyrifos was mediated by the cometabolic ...

Safety of Safety Evaluation of Pesticides: developmental neurotoxicity of chlorpyrifos and chlorpyrifos-methyl [PDF]
Environmental Health, 2018 Authorization of pesticides for market release requires toxicity testing on animals, typically performed by test laboratories on contract with the pesticide producer. The latter provides the results and summary to the regulatory authorities. For the commonly used pesticide chlorpyrifos, an industry-funded toxicity study concludes that no selective ...

Study of the protective role of polyphenol antioxidants from extracted Damiana (Turnera diffusa Willd) against chlorpyrifos pesticide-induced toxicity in male rats [PDF]
Journal of Bioscience and Applied Research, 2023 Pesticides have been associated with oxidative stress and enhanced reactive oxygen species generation (chlorpyrifos). This study aimed to determine whether extracted damiana (Turnera diffusa Willd) may effectively prevent chlorpyrifos-induced toxicity in
