Mutagenicity of 5-nitroacenaphthene in salmonella

5-Nitroacenaphthene was proved to be mutagenic on TA100 and TA98 of Salmonella typhimurium with or without metabolic activation by S-9 Mix. A possible metabolite, 5-hydroxyacenaphthene, carcinogenicity of which had not been observed, was non-mutagenic on TA100 and TA98, with or without metabolic activation.
