Selected Organochlorines in Human Blood and Urine in the South of the Russian Far East.

ABSTRACT

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.
