The fate of pesticides in the environment and its biological purification

Pesticides are substances in liquid, solid or gas form that are used to destroy pests. Some of these pests that are not liked by humans are insects, weeds and microbes that destroy plants. The negative effect of pesticides on the environment has been fully proven, and the resistance of pesticides in the environment and their non-degradation have endangered the lives of many living organisms.Persistent organic pollutants (POPs) are chemical substances that remain in the environment for a relatively long time and upon entering the food chain, accumulate in living tissues and have adverse effects on human health and the environment. In general, these compounds are produced by human activities in different ways.The most famous persistent organic pollutants include chlorine, aldrin, crodan, dedet, dieldrin, dioxin, andrin, norans, heptachlor, hexachlorobenzene, Mirex, toxaphene, polychloride, biphenyls pesticides.So that by optimal and standard use and reducing the use of such chemical poisons (use of biological control methods) we can reduce the harmful effects on the environment.
