Abstract

19 aromatic amines were assayed for mutagenicity using Salmonella typhimurium strains TA98 and TA100 with and without the addition of S9 from Aroclor-1254-induced rat liver. These included: naphthalenes (1-amino-, 1-acetamido-, 2-amino-, 2-acetamido-, 1-amino-4-nitro- and 2-amino-1-nitro-), biphenyls (2-amino-, 2-acetamido-, 4-amino- and 4-acetamido-), fluorenes (2-amino- and 2-acetamido-), anthracenes (1-amino-, 1-acetamido-, 2-amino- and 2-acetamido-), 3-aminofluoranthene, 1-aminopyrene and 6-aminochrysene. None of the compounds were mutagenic when tested without S9. With S9, 15 of 19 were mutagenic for TA98 and 16 of the 19 were mutagenic for TA100. Overall, 2-aminoanthracene was the most potent mutagen. When compared to the parent amines, the respective acetamido derivatives were consistently less mutagenic.
