Abstract:
Metabolites of BaP formed by 3-MC-induced goldfish (Carassius auratus), black bullhead (Ictalurus melas), brown bullhead (Ictalurus nebulus) and rat have been separated by HPLC. The main metabolites in both bullhead species and the rat were 3-hydroxy-BaP and BaP 9,10- and 7,8-dihydrodiols, whereas BaP 1,6- and 3,6-diones and 9- and 3-hydroxy-BaP predominated in the goldfish. Induced rat formed over 10 times as many total metabolites as the fish. No induction was observed in the 3-MC-treated brown bullheads kept at 7 degrees C. TCPO and alpha-naphthoflavone decreased metabolite production by 50 and 30%, respectively.
