在有机氯污染的研究中，氯同位素（37Cl）的应用能够在原子水平上识别污染源并研究污染机理，为更加有效地研究地下水的有机污染提供了有利的工具。综述了8种氯代VOCs氯同位素的测试方法与技术，论述了氯代VOCs氯同位素在识别地下水污染源、监测有机污染物的降解过程、检验防治措施的修复效果、鉴别氯代VOCs的生产厂商、示踪氯代VOCs在土壤和水体中的迁移和混合过程等方面的应用，认为应尽快在国内研制先进的测试流程，开展有机氯同位素分馏机理的研究，加强应用C和Cl同位素技术对氯代VOCs污染和检测修复效果的研究。

Organic contamination in groundwater and the impact on human health have been a growing concern. In the study of organic chlorine pollution, applying chlorine isotope (37Cl) can be applied to identify pollution sources and to study pollution mechanism at the atomic level, providing a favorable tool for more effective work on the organic pollution of groundwater. In this paper, eight kinds of chlorinated VOCs chlorine isotopic testing methods and techniques were discussed on the basis of the literatures information at home and abroad. And some applications of the chlorinated VOCs chlorine isotopes were shown, including the identification of groundwater pollution sources, monitoring the process of degradation of organic pollutants, verifying results of the restoration measures, distinguishing the manufacturers of Chlorinated VOCs and tracing the migration and the mixing process of chlorinated VOCs in soil and water. Advanced testing process should be developed and studies should be carried out on the mechanism of organic chlorine isotopes fractionation as soon as possible in China. At the same time, the use of C and Cl isotopes technology in chlorinated VOCs contamination and restoration should also be enhanced.
