title: Mutagenic activity of vinyl compounds and derived epoxides.
abstract: Many vinyl compounds, such as vinyl chloride and some inhalational anesthetics, are known to be mutagens. In the present study, 10 vinyl compounds or derived epoxides, widely used in industry, were assayed in the Salmonella typhimurium/mammalian microsome system. 3 strains of histidine-dependent S. typhimurium, TA1535, TA98 and TA100 were used. Of the 10 compounds, 4 were mutagens. They were 9-vinylanthracene, vinylcarbazole, 3-vinyl-7-oxabicyclo[4.1.0]heptane and 3-epoxyethyl-7-oxabicyclo[4.1.0]-heptane. The study confirmed the overall genotoxicity of vinyl compounds and epoxides and the need to carefully screen them for mutagenic/carcinogenic effects.
