title: Mutagenicity of aliphatic nitrosamines in Salmonella typhimurium.
abstract: 25 aliphatic nitrosamines were examined in the Ames assay for bacterial mutagens, using rat liver "S-9" for activation. Of them, 8 carcinogens were mutagenic and 5 non-carcinogens were not mutagenic. However, 2 compounds not carcinogenic in rats were mutagenic and 9 carcinogens were not mutagenic, including 6 that are liver carcinogens in rats.
