TSCA Test SubmissionsThe mutagenicity of O,O-diethyl phosphorodithioate was evaluated in Salmonella tester strains TA98, TA100, TA1535, TA1537 and TA1538 (Ames Test), both in the presence and absence of Aroclor-induced rat liver S9 metabolic activation. Based on preliminary toxicity determinations, O,O-diethyl phosphorodithioate, diluted in DMSO, was tested at concentrations up to 5000ug/plate using the plate incorporation technique. O,O-diethyl phosphorodithioate did cause a positive response in tester strains TA1535 and TA100 with and without metabolic activation.
