New method for determination of organochlorine pesticides (DDT and its metabolites, HCH and its isomers) is presented. The method includes a liquid-liquid extraction of pesticides under ultrasound and the substance analysis by gas-liquid chromatography. The degree of DDT and γ-HCH extracting from tissues of marine organisms is (78 ± 2) % and (91 ± 2) %, respectively. The total content of organochlorine pesticides in muscles of walleye pollock from the Okhotsk Sea is evaluated by this method in the range from 25 to 73 pg/g of lipids.
