Monarh V. The assessment of the environmental risk of agroecosystem components pollution by pesticides

The thesis focuses on improvement of the system ecotoxicological monitoring of pesticides by including the assessment of the environmental risk of agroecosystem components pollution. The range of pesticides used in the system of chemical crops protection in agricultural sector of Vinnytsia region has been studied in detail; while the preparations were characterized for hazard classes, chemical composition, purpose and active substances. It has been defined, that stores of obsolete pesticides in Kryzhopil district are dangerous source of soils, crops and water pollution by pesticides with different chemical composition by field and analytical research. The mathematical calculation model of situational risk from pesticide pollution for farming lands bordering the stores of obsolete pesticides has been improve on. The algorithm of the assessment of the environmental risk of agroecosystem components pollution by pesticides was set up.
