Because DCVC and TCVC can also be bioactivated through sulfoxidation to yield the potent nephrotoxicants S - ( 1 , 2 - dichlorovinyl ) - l - cysteine sulfoxide ( DCVCS ) and S - ( 1 , 2 , 2 - trichlorovinyl ) - l - cysteine sulfoxide ( TCVCS ) , respectively , the mutagenic potential of these two sulfoxides was investigated using the Ames Salmonella typhimurium TA100 mutagenicity assay .
