摘要
饮用水氯化消毒副产物中的卤乙酸由于具有较强结合氯的能力,较强“三致”(致癌、致畸、致突变)作用,较高单位致癌风险性,成为国内外近几年给水处理研究的重点。本文从卤乙酸的形成机理、影响因素、毒理作用及去除方法等几个方面对最近国内外关于卤乙酸的研究工作进行了较为具体的阐述,并对卤乙酸今后研究的重点进行展望。
Haloacetic acids（HAAs） in drinking water have attracted more and more attention of researchers due to their higher potential combination of chlorine, their carcinogenic and mutagenic effects and higher carcinogenic. The formation mechanism, analytical methods, the effects of many factors on HAAs formation such as precursor types, chlorine doses, pH, temperature, bromide, reaction time and seasonal change, toxicological character and the minimizing technology of HAAs in resent studies about HAAs are discussed in details in this paper. Further researches are still needed to clarify the formation mechanism of HAAs and find a feasible minimizing technology. New concerns including toxicological characters that correlate with human and other HAAs exposure routes besides oral ingestion （ i. e., inhalation and dermal adsorption） should be put forward.
