摘　　要：消毒工艺是保障饮用水微生物安全的关键措施,而由消毒剂与前体物反应生成的消毒副产物(DBPs)被发现具有潜在的健康风险。尽管饮用水中大多数已被识别的DBPs是卤代有机物,但在消毒后出水中,已知的DBPs所含有机卤素的浓度之和在总有机卤素(TOX)检测值中的占比通常不超过50%。由此,TOX作为一项可代表所有卤代有机DBPs的综合性参数和毒性指标而在饮用水消毒及DBPs研究中广受关注。针对饮用水中TOX的分析方法,介绍了两类已有国内外标准指导的常规检测方法,讨论了检测过程中可能干扰分析结果的影响因素,对比了几类新型TOX检测方法并汇总了饮用水中TOX的浓度水平,最后提出了有关TOX分析研究的展望。Disinfection is a key measure for ensuring the microbiological safety of drinking water,while disinfection by-products(DBPs)formed by the reaction of disinfectants and precursors have been reported to pose potential health risks.Although most of the identified DBPs are halogenated organics,in most cases,no more than 50%of the total organic halogen(TOX)detected in disinfected drinking water could be attributed to known single species.Therefore,TOX,as a collective parameter and a toxicity index of all halogenated organic DBPs,has been widely concerned in the field of disinfection and DBPs research.Focusing on the analysis method of TOX in drinking water,this paper introduced two standard methods,and then discussed the influencing factors during TOX analysis.In addtion,several novel TOX analytical methods were introduced,and the concentration levels of TOX in drinking water were summarized.Finally,the development trends and research requirements of TOX analysis were put forward.
