摘要
水消毒是保护人体健康免受病原体侵害并防止病原体在水中传播的基本策略,已被广泛应用于水质净化中.在水消毒过程中,消毒剂易与天然存在的有机物(如腐殖酸和富里酸)、无机物、污染物以及原水中存在的游离氯、溴或碘反应,生成新型污染物(emerging contaminants,ECs)消毒副产物(disinfection by-products,DBPs),其中氯代消毒副产物(chlorinated disinfection byproducts,Cl-DBPs)是检出率和浓度水平最高的一类.Cl-DBPs可引发内分泌紊乱及"三致"效应,对生态环境和人体健康均构成了一定的威胁,然而造成这些不良影响的毒性机制在很大程度上尚不清楚.因此,全面了解Cl-DBPs的毒性效应对保护生态环境和人体健康至关重要.本文综述了目前已发现的Cl-DBPs的种类和来源,探讨了 Cl-DBPs及其混合物对水生生物、陆生生物、人体健康的毒性效应,为评价Cl-DBPs的环境风险提供科学依据.
Abstract
Water disinfection is a fundamental strategy for safeguarding human health from pathogenic threats and preventing the spread of pathogens in drinking water.It has been widely employed in water purification.During the process of water disinfection,disinfectants readily react with natural organic matters such as humic and fulvic acids,inorganic compounds,pollutants,and free chlorine,bromine,or iodine present in the raw water,producing pollutants known as emerging contaminants(ECs)or disinfection by-products(DBPs).Among these,chlorinated disinfection by-products(Cl-DBPs)represent a category with the highest detection rate and concentration levels.The toxicities of Cl-DBPs include endocrine disruption,carcinogenicity,teratogenicity,and mutagenicity,which can threaten human health and environmental safety.However,the toxic mechanisms responsible for these adverse effects are not yet fully understood.Hence,gaining a comprehensive understanding of the toxic effects of Cl-DBPs is crucial for safeguarding both ecological environments and human health.This article provides an overview of the types and sources of Cl-DBPs that have been identified so far.It delves into the toxic effects of Cl-DBPs and their mixtures on aquatic organisms,terrestrial organisms,and human health,thereby offering a scientific foundation for assessing the environmental risks associated with Cl-DBPs.
