Abstract

Despite the high toxicity and obvious risk to the environment, pesticides are still widely used worldwide in order to increase the yield. Since their use in agriculture is regulated, the sites of obsolete pesticides, which are improperly managed, cause the most danger. Pesticides are persistent, and therefore to minimize the potential harm, their pathways in the nature should be studied. In this article it was identified the factors and processes that determine the fate of persistent organic pollutants (PoPs). Factors can be divided into four main groups: characteristics of pesticides; characteristics of the soil and agronomic factors (humus content, grain size, pH, density, structure, presence of vegetation); climate; the feature of the input of the chemical. The processes are: adsorption, chemical and biological transformation, and convectional transfer. The migration of pesticides from permanent sources has its patterns, for instance, high concentration of pollutant change the composition microorganisms and biological degradation. Therefore, the physical model of pesticides migration was offered. Taking into consideration the importance of prevention of environmental pollution, this topic requires future thorough study.
