title: Lack of mutagenicity and putative carcinogenicity of several novel benzopyrene derivatives.
abstract: Several novel benzopyrene derivatives with the same gross structure and the same electronic periphery  as benzo(a)pyrene, but with some alteration in the complete electronic structure, when tested in the Ame's Salmonella/microsome test (TA 1537, TA 100 and TA 98], were found to lack mutagenicity and, therefore, putative carcinogenicity.
