Assessment of the environmental fate of pesticides and their ecotoxicological impact on soil microorganisms : the case of chlorpyrifos, isoproturon and tebuconazole

Pesticides are mainly applied to cultivable soils in agriculture to protect crops from various pests. Only a tiny part of sprayed pesticides ends up in their target organisms, while the rest persists on plants or in soil from where it can disperse to surrounding environments and harm non-target organisms. To minimize environmental damage caused by pesticides, their environmental fate and potential impact on non-target organisms is evaluated in an environmental risk assessment procedure by EU-authorities before their authorization and introduction to the market. The pesticide approval process is criticized for compromising a non-precautionary principle, as numerous formerly used pesticides a…

Evaluation of the environmental fate and ecotoxicological impact of the pesticide chlorpyrifos in soil for improvement of its environmental risk assessment

EABIOMEUBINRA; Pesticides protect crops from various pests but can also harm nontarget organisms. To minimize risks for the environment and human health, a huge amount of studies are carried out and evaluated during the authorization process of each pesticide. However, the prediction of the environmental fate and ecotoxicological impact of a pesticide remains difficult. Several 100 formerly used pesticides are now banned because unexpected risks emerged decades after their authorization. Risk assessment documents of the organophosphate insecticide chlorpyrifos (CHL) particularly lack information about its degradation and potential transformation products in soil, and its impact on non-targe…
