中文摘要：

卤代腈（氰）是水处理过程中产生的一类含氮的氯化消毒副产物。鉴于这种物质有极强的致畸和致突变性,其细胞毒性也远大于三卤甲烷和卤乙酸等常规消毒副产物,因此成为近年来饮用水中颇受关注的含氮消毒副产物种类之一。卤代腈（氰）在水厂出厂水中被大量检出,其质量浓度基本维持在μg/L,而采用氯胺消毒的出厂水中其浓度明显高于自由氯消毒方式。重点对卤代腈（氰）的物质种类、理化特性、遗传毒性、生产机制、检测方法及控制方法进行综述。鉴于多数卤代腈（氰）类消毒副产物均具有含量低、亲水性强等特点,若生成将难以在饮用水处理工艺中有效去除,因此如何有效控制其生成是卤代腈（氰）研究的主要发展方向。

英文摘要：

Halogenated nitrile was a kind of nitrogen containing disinfection byproducts which produced in drinking water chlorination.These substances shows highly carcinogenic and mutagenic indeed and their toxicity was higher than traditional DBPs,such as Trihalomethanes（THMs） and the Haloacetic acids（HAAs）.Base on the comprehensive literature review,the physical and chemical characteristics of the typical halogenated nitriles and their toxicity on CHO cell were introduced,the concentration level of typical halogenated nitriles,such as cyanogen chloride（CNCl） and haloacetonitriles（HANs）,in output water treated by different disinfection methods or at different treatment stages was summarized,and the formation mechanism of halogenated nitriles was also described in detail.Since halogenated nitrile shows low concentration and high polar fractions,very limited removal can be achieved in the conventional treatment process.Thus,research on their formation control of halogenated nitrile should be stressed in drinking water treatment.
