Genetic effects of chlorinated anilines and azobenzenes on Salmonella typhimurium.
The mutagenicity of 19 herbicide-derived chlorinated azobenzenes and structurally related chlorinated anilines and nitrobenzenes was assayed towards several strains of S. typhimurium, using the plate incorporation method and the fluctuation test, in the presence or in the absence of liver post-mitochondrial fractions, in aerobic and anerobic conditions. Positive results were obtained with 4,4'-dichloroazobenzene, 4,4'-dichloroazoxybene, 3,4-dichloronitrobenzene and, to a much lesser extent, with 3,4,3',4'-tetrachloroazobenzene. No mutagenic effect was observed with 2,3,7,8-tetrachlorodibenzo-p-dioxin in any condition.
