Abstract | Cultured bladder and tracheobronchial explants from human, monkey, dog, hamster, and rat were used to study the metabolism, covalent binding to DNA, and DNA:adduct formation of (3H0benzo(a)pyrene (BP). Both organs from all species formed large amounts (40 to 70% of total 3H in the medium after 24 hr of incubation) of polar material and small amounts (<1% for animal tissues and 1 to 5% for human tissues) of organic solvent-extractable (unconjugated) metabolites, with the balance (14 to 38%) being unmetabolized BP. |
