Modern modification of the method for determination of organochlorine pesticides in organic vehicles

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 ti...

Description
Summary: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.
