SpletMany organisms dechlorinate tetrachloroethene (PCE) to trichloroethene (TCE) and cis -1,2-dichloroethene ( cis -DCE), and recent study demonstrated that trans -DCE can also be a major product of microbial PCE/TCE metabolism (3) . All chlorinated ethenes are toxic, and only complete dechlorination results in detoxification.
