WebIn the late 1980s and 1990s, it was discovered that PCE and TCE could be reductively dechlorinated to ethene under anaerobic conditions. The successive dechlorinations of PCE lead to TCE, then dichloroethylene (cis- or trans-DCE), and vinyl chloride (VC) (Fig. 4). VC is the most hazardous of the family, but its dechlorinated product, ethylene ...

Webattenuation as a remedy for chlorinated solvents such as perchloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE), and vinyl chloride (VC) in ground water. The reader is urged to consult other excellent resources on natural attenuation (1, 27, 42, 50, 59, 60). What is a natural attenuation remedy? Webreductive dehalogenation of common industrial solvents trichloroethylene, tetrachloroethylene, and 1,1,2,2-tetrachloroethane. The cis-1,2-dichloroethylene is apparently the more common isomer found although it is mistakenly reported as the trans isomer. The trans-isomer, being a priority pollutant, is more commonly analyzed for
WebThe maximum level detected in drinking water was 1,400 μg/L in May 1982. The current limit for TCE in drinking water is 5 μg/L. Other contaminants detected in finished water at the Hadnot Point treatment plant included DCE (trans 1,2-dichloroethylene), PCE, benzene, and vinyl chloride. DCE was detected at a maximum of 407 μg/L in January 1985. WebMar 22, 2024 · Here are some of the major differences between them: 1. Ozone Depletion. TCE is not considered an ozone-depleting chemical, as it has a very short atmospheric lifetime and breaks down before reaching the ozone layer. Trichloroethane, on the other hand, was shown to significantly contribute to ozone depletion and was banned by the …
