RESUMO
The trace OCP concentrations, such as α-, ß-, and γ-HCH, DDT and its metabolites (DDD and DDE) in blood and urine of residents from the south of the Russian Far East was revealed. A large range of OCPs was found in the urine: α- and γ-isomers of HCH, DDT and DDE. The only ß-HCH was detected in the blood; this indicates its persistence and the difficulty of excretion this substance from the organism. The total trace OCP concentration, found in the biological fluids of residents of the south of the Russian Far East, providing further evidence that these organic contaminants persist in the environment.

The content of organochlorine pesticides in blood of residents of the Russian Far East is assessed. Among hexachlorocyclohexane isomers, only ß-HCH has been found. This fact indicates that contamination of the environment and human organisms by this pesticide began long ago. Its concentration varies from 2060 to 22,230 ng/g lipid. The probable sources of the toxicant found in human organisms are discussed.
