| Abstract |
The American oyster (C. virginica) was used as the experimental animal for chronic exposure to 3-methylcholanthrene (3-MC) and benzo(a)pyrene (BP) in an exposure system in which the carcinogens can be continuously injected into free flowing water at fixed rates ranging from 1 to 5 micrograms/l. Experiments designed to determine uptake and distribution of 14C-MC and 14C-BP showed that these are concentrated in oyster tissues in direct proportion to the dosage of carcinogen injected into the system. Residual concentrations as high as 84.4 micrograms/kg of BP were present in oysters as long as 6 months following exposure. Autoradiography showed intense localization of 14C-BP in distal portions of the tubules of the digestive gland and to a lesser extent in the gonadal tissues. |
