摘　　要：含氮消毒副产物(N-DBPs)作为饮用水中一类新兴的消毒副产物,因其与含碳消毒副产物(C-DBPs)相比具有更强的“三致”(致畸、致癌、致突变)作用,且由于国内标准法规未对其浓度含量进行限定及监测,因此其危害更加隐蔽,近年来受到广泛关注。对卤乙腈(HANs)、卤乙酰胺(HAcAms)、卤代硝基甲烷(HNMs)、亚硝胺(NMs)等新型N-DBPs的毒理性质、形成机理及控制技术进行了梳理归纳,总结了现有不同N-DBPs的前处理技术及其原理。对新材料在前处理富集过程中的应用前景进行了展望,以期为实现饮用水N-DBPs的痕量检测及有效监测提供参考。Nitrogenous disinfection by-products(N-DBPs),as a kind of emerging disinfection byproducts in drinking water,have stronger teratogenic,carcinogenic and mutagenic effects compared with carbonaceous disinfection by-products(C-DBPs),and their concentrations are not limited and monitored by domestic standards and regulations,so their hazards are more hidden,and give rise to be widely concerned in recent years.In this paper,the toxicological properties,formation mechanism and control technology of new N-DBPs such as haloacetonitriles(HANs),haloacetamides(HAcAms),halonitromethanes(HNMs)and nitrosamine(NMs)were summarized,and the pre-treatment technology and principle of different N-DBPs in existing research were summarized.The application of the new materials in the pretreatment enrichment process were prospected,which provided a literature basis for the realization of trace detection and effective monitoring of N-DBPs in drinking water.
