摘要:
综述了水中亚硝胺类消毒副产物的来源、浓度水平及限定标准,以及亚硝胺类物质(NAs)的生成机制、分析检测技术、控制与去除方法。指出,随着人们对饮用水安全消毒的重视和污水消毒的推广,应增加大范围水中NAs污染水平的调查工作,以及对复杂污水体系中NAs生成前体物的研究,优化和改进消毒工艺,减少NAs的生成,针对复杂水样建立准确可靠的NAs检测方法。

Abstract:
Nitrosamines (NAs), are one class of emerging disinfection by-products in water. This paper summarized the sources, concentrations and the standard limit, the formation mechanism, the analysis and detection techniques, the control and removal methods of NAs. With the emphasis on the disinfection of drinking water and the promotion of sewage disinfection, it was suggested that it should be necessary in increasing the survery of NAs levels in a wide range of water and investigateing the precursors of NAs formation in complex sewage systems, and then optimizing and improving disinfection technologies to reduce the formation of NAs and establish accurate and reliable detection methods of NAs in complex water samples.
Key words:  Nitrosamines  Disinfection by-product  Occurrence  Formation mechanism  Detection  Control and elimination
