Features of pesticides accumulation in soils

Abstract

Features of pesticides accumulation in soils was studied. We investigated the content of pesticides in the soils of villages of the Kyiv region. According to our calculations for 2026 in the soils of certain settlements of Ukraine: the villages of Tarasivka, Huta Mezhyhirska, Zgurivka (sampling depth 5 centimetres) – ΣDDT is at the level of 10-8–10-5 mg/kg. It has been studied that the depth of pesticide migration along the soil profile is inversely proportional to the adsorption coefficient, humus content and pH value. Regular monitoring of soils and groundwater quality is required. If the levels of pollution of natural environment objects will increase (exceeding the maximum permissible concentration) then it is necessary to reduce to load of pesticides on agricultural lands and replace old pesticides with new ones. Formation of a balanced environmental management system in the context of sustainable development and the introduction of environmental and innovative technologies in agriculture is required. Formation and implementation of modern mechanisms of national environmental policy is required.
