摘要：Objective. We evaluated a potential ecological and hygienic danger of the use of Vertimec 018 EC and Proclaim 05 SG on berries, fruits, vegetables and hops based on the study of the active ingredients of the residues in soil, plants and agricultural products. Materials and Method. The field studies were carried out in different agro-climatic zones of Ukraine (woodlands, forest-steppe, steppe). Treatment of the crops was performed in the highest recommended norms and ratio of applications. Sampling of soil, leaves and fruits was performed during growing season from the day of last treatment till harvesting. Determination of avermectine residues was performed by the method of reversed-phase high-performance chromatography using a fluorescence detector. Determination of the maximum residue levels (MRL) of test compounds in agricultural products and their approximate permissible concentration in soil was conducted in accordance with “Guidelines on the hygienic evaluation of new pesticides”. To assess the stability of abamectin and emamectin benzoate in soil and plants degradation the half-life periods were calculated; ecotoxicological risk was defined by the Melnikov method. Results. In conditions of Ukraine the abamectin and the emamectin benzoate (active ingredients of the products Vertimec 018 EC and Proclaim 05 SG) are low-stable in the soils and the vegetating crops. We substantiated MRLs for abamectin: 0.01 mg/kg – in cucumbers,0.02 mg/kg - in strawberries, apples, peppers, eggplants, 0.1 mg/kg – in hops; for emamectin benzoate: 0.01 mg/kg - in apples, grapes, cabbage, tomatoes. When following established MRLs, intake of abamectin and emamectin benzoate by human body will not exceed respectively 60.8% and 9.1% of acceptable daily intake. Potential ecotoxicological risk at the use of abamectin and emamectin benzoate in agro-climatic zones of Ukraine is respectively 154 and 2347 rates lower than at the use of DDT (dichlorodiphenyltrichloroethane).
