当用一个~（13）C原子标记三氯乙烯（TCE）并采用气相色谱/质谱法监测1，2-二氯乙烯-~（13）Cx（DCE）的产生时，已经证明土壤中发生了TCE的还原脱氯。在这个过程中的微生物参与表明，因为未灭菌的土壤样品产生了高达78 ppb的标记的DCE，而灭菌的土壤样品没有产生。还发现了异构体特异性;仅产生1，2-DCE-未观察到1，1-DCE。
When trichloroethylene (TCE) isotopically labeled with one 13C atom is used and gas chromatography/mass spectrometry is employed to monitor the production of l, 2-dichloroethylene-13Cx (DCE), it has been demonstrated that reductive dechlorination of TCE takes place in the soil. Microbial involvement in this process is indicated since unsterilized soil samples yielded up to 78 ppb of labeled DCE while sterilized soil samples produced none. Isomer specificity was also found; only 1, 2-DCE was produced—no 1, 1-DCE was observed.
