A series of new metallized direct dyes based on benzidine congeners, 2,2′-dimethyl-5,5′-dipropoxybenzidine and 5,5′-dipropoxybenzidine,
were evaluated for mutagenicity in Salmonella typhimurium strains TA98 and TA100. All of the dyes examined were judged to
be non-mutagenic with and without metabolic activation while toxicity was seen in some dyes at high doses. The study also
suggested that the standard Salmonella mutagenicity plate-incorporated assay was an excellent method for evaluation of dyes
for mutagenicity. 相似文献

The influences of a series of new azo direct dyes including copper-complexes based on benzidine congeners, 2,2′-dimethyl-5,5′-dipropoxybenzidine
and 5,5′-dipropoxybenzidine, were examined using microorganism, Daphnia magna. The purpose of the research described in this
paper was to use bioassays with daphnids to determine the aquatic toxicity of new azo dyes in which copper was incorporated.
The results clearly show that copper has negative effects to aquatic ecosystem as expected. The study also suggested that
the assay with Daphnia magna was an excellent method to evaluate the influences of dyes to the aquatic environment. 相似文献
