Abstract

Monitoring of organochlorine pesticides (OCPs) was carried out and disperse-phase distribution of them was studied in natural water from Dnieper River in Kiev region during the period between 2011 and 2013 years. Total concentration of OCPs (α-HCH, β-HCH, γ-HCH, HCB, heptachlor, aldrin, 4,4’-DDE, 4,4’-DDD, 4,4’-DDТ) range from 1.4 to 17.1 ng/dm3. Concentrations of compounds of groups of HCH and DDT are situated in intervals respectively: 1.42 – 6.43 ng/dm³; 1.26 – 15.76 ng/dm³. It was indicated that dominant part of OCPs is associated with suspended particles: 16 – 25 % ― at thin and 37– 52 % ― at rough fractions. The dissolved fraction of OCPs is accounted only 24–38 %.
