Abstract excerpt
The environmental pollutants 1- and 3-nitrobenzo[a]pyrene (1- and 3-NBaP) are metabolized by mammalian microsomes through ring oxidation to 1-NBaP trans-7,8-dihydrodiol and 3-NBaP trans-7,8-dihydrodiol, and by nitroreduction to 1- and 3-aminobenzo[a]pyrene. To determine if these compounds are tumorigenic, 1- and 3-NBaP, along with several of their metabolites and the parent benzo[a]pyrene (BaP) and its...
