A protocol for producing 14 C 2 -cis-1,2-dichloroethylene ( 14 C 2 -cis-DCE) from 14 C 2trichloroethylene ( 14 C 2 -TCE) was developed as an economical alternative to commercial, custom synthesis of 14 C 2 -cis-DCE. The method uses 5,10,15,20tetrakis-(4-carboxyphenyl) porphyrin cobalt(II) as a catal

Abstract
Trichloroethylene (TCE) and dichloroethylene (DCE) are highโvolume industrial chemicals frequently found as contaminants in public drinking water supplies. The developmental toxicity of both chemicals has been evaluated in laboratory and epidemiologic studies. It has been suggested that TCE and DCE are specific cardiac teratogens and that drinking water contaminated with them increases the risk of congenital heart defects in exposed human populations. In contrast, other laboratory and epidemiologic studies do not find an increase in developmental effects, either in general or specifically affecting the heart. This laboratory and epidemiologic base was reviewed to evaluate the strengths and weaknesses of the conflicting published reports. We conclude that the weight of experimental and epidemiologic evidence does not support the hypothesis that TCE or DCE is a selective developmental toxicant in general or a cardiac teratogen specifically.
