title: [Possibility of tissue accumulation and elimination of 3,4-benzpyrene from the bodies of fish].
abstract: One-year and two-year iridescent trout and two-year carp during different periods (from 2 months to 1 year) were given protein-vitamin addition to food containing 3,4-benz-pyrene (BP). The total amount of BP entering the organism of fish for the whole period of the experiment reached 12,6 mg/Kg of fish weight in daily dosage ranging from 0.1 to 4.1 m/Kg. In fish tissues BP was either not detected at all, or the content of the carcinogen in them did not exceed its amount in the control. In summer BP was not excreted in feces, but in winter its excretion made 13% of its daily consumption with food.
