abstract：:S-(chloroethyl)-cysteine (CEC) and S-(1,2-dichlorovinyl)-cysteine (DCVC) have been proposed as intermediates in the metabolic transformation of the carcinogens 1,2-dichloroethane and 1,1,2-trichloroethylene. We have tested the ability of CEC and DCVC to induce DNA repair and genotoxic effects at the chromosomal level ...
