摘　　要：N-亚硝基二甲胺(NDMA)是近年来发现的水或废水氯消毒的副产物,被美国环境保护署认定为可疑致癌化合物。介绍了NDMA的形成机制及其与NDMA前体物的来源,综述了NDMA及其前体物在污水处理厂中的去除现状和去除技术。在此基础上,展望了NDMA及其前体物的未来研究方向,提出了开展国内NDMA研究工作的必要性。N-nitrosodimethylamine （NDMA）, a disinfection byproduct in drinking water and wastewater treatment plants, has been identified as a suspected carcinogenic compound by the U.S. Environmental Protection Agency. Based on an extensive literature review, the paper summarized the formation of NDMA, the sources of NDMA and its precursors, their removal in municipal wastewater treatment plants, and the methods for inhibiting the transformation of the precursors. The paper furthermore forecasted directions of future research in NDMA and its precursors and also presented the needs for more NDMA studies in China.
