title: Evaluation of the mutagenic potential of endosulfan using the Salmonella/mammalian microsome assay.
abstract: The mutagenic potential of endosulfan, a polychlorinated insecticide, was assessed using the highly sensitive Salmonella tester strains TA97(a), TA98, TA100 and TA102. It exhibited a toxic effect at dose levels of 50 micrograms/plate and higher. Plate incorporation studies did not show mutagenic response with any of the tester strains used. A modification of the assay using a preincubation procedure showed mutagenic activity with and without metabolic activation with TA97(a) only. Increased toxicity was observed after addition of phenobarbital-induced S9 mix.
