Abstract excerpt
Both 1- and 3-nitrobenzo[a]pyrene (nitro-BaP) are environmental contaminants, potent mutagens in Salmonella, and moderate mutagens in Chinese hamster ovary (CHO) cells. The mutagenicity of their oxidized metabolites,trans-7,8-dihydroxy-anti-9,10-epoxy-7,8,9,10-epoxy -7,8,9,10-tetrahydro-1-nitrobenzo[a]pyrene (1-nitro-BaP-DE) and trans-7,8-dihydroxy-anti-9,10-epoxy-7,8,9,10-tetrahydro-3-nitrobenzo[a]- pyrene...
