Pesticide Exposure and Toxicity

Chlorpyrifos is a commonly used pesticide that belong to the organophosphorus pesticides (OPPs) group. Chlorpyrifos is widely used in residential environments and agriculture for pest control. As many OPPs, Chlorpyrifos degrades faster to more complex and toxic compounds under natural conditions, thus diverse effects of these compounds over aquatic species are unknown. Due to the risk that pesticides as Chlorpyrifos, which mainly breaks down to 3,5,6- trichloro-2-pyridinol (TCP) on the ecosystems, there is an increasing need to intensify the environmental monitoring and ecotoxicological risk assessment for both substances. Risk assessment provides a systematic approach for characterizing the nature and magnitude of the risks associated with environmental health hazards. However, in countries like Colombia, where the use of Chlorpyrifos is widespread, the number of investigations on the dynamics and risk involved in the presence of this class of substances in water bodies is limited.
