[Benz(a)pyrene accumulation, distribution and excretion in fish]

The data are reported on the level of benz(a)pyrene /BP/ in muscular tissue and various organs of carp, drown trout, seatrout and rainbow-trout. It has been found that the average content of BP in fish was, as a rule, less than 1 mg/kg. The amount of BP in various organs was nearly the same as in the muscular tissue. The food of rainbow trout contained a large amount of BP and so did excrements of this fish. The results obtained allowed a conclusion to be made that some amount of BP does not metabolize in the organism of fish.
