摘要：The purpose of this paper is to present and discuss: pesticide environmental effects, eliminating pesticides, pesticide classification, pest resistance, persistent organic pollutants human effects. The pesticides are used to destroy the crop pests, in order to increase the yield and quality of the products. However, many pesticides can pose a risk to human health. Human exposure to pesticides can occur by eating contaminated food and drinking water, in people handling and working with pesticides. Pesticides also have negative effects on the environment (water, soil, air). There are intense concerns about the dosing of pesticides in the environment and food, in order to assess their risk to human health. This tendency is accentuated by the uncertainty of agricultural and industrial production methods, as well as by the control of pesticides. The probability of reducing the environmental risk associated with pesticide use is very low because many manufacturers consider that by avoiding pesticides or reducing doses, the yield on agriculture decreases and increases production costs. Current policies on pesticides, their role and their various implications, advocate the selection of the most effective pesticides that are specific to crop classes, corroborated with research and innovation on how to increase the quality of pesticides and their costs.
