摘要
卤代硝基甲烷(HNMs)是饮用水消毒过程中常见的一类含氮消毒副产物(N-DBPs),相比已受监管的消毒副产物(DBPs)具有更强的细胞毒性和遗传毒性.本文简述了HNMs在水中分布特点和来源,并从致突变性、细胞毒性、遗传毒性、致癌性等方面总结了其毒性效应和毒性机制,以期引起广大人群对HNMs的关注,为饮用水安全保障和HNMs控制提供科学参考依据.
Halonitromethanes(HNMs)are one group of nitrogenous disinfection by-products(NDBPs)formed during the disinfection of drinking water,which have stronger cytotoxicity and genotoxicity than regulated disinfection by-products(DBPs).In this paper,the distribution characteristics in water and the source of HNMs were briefly introduced.The toxicological effect and mechanisms of HNMs were systematically summarized on the aspects of mutagenicity,cytotoxicity,genotoxicity and carcinogenicity to arouse the public’s attention to HNMs.It will provide the appropriate scientific reference for drinking water safety and HNMs control.
