本文件旨在对饮用水中未经监管的消毒剂氯胺-T及其主要降解物和代谢物对甲苯磺酰胺进行毒理学评估，作为根据NSF/ANSI 60（2017）评估的饮用水处理化学品。非癌症终点和癌症终点都得到了考虑，并且使用了美国环境保护局（U.S.EPA）开发的风险评估方法。

This document has been prepared to allow toxicological evaluation of the unregulated disinfectant chloramine-T and its primary degradant and metabolite, p-toluenesulfonamide, in drinking water, as drinking water treatment chemicals evaluated under NSF/ANSI 60 (2017). Both non-cancer and cancer endpoints have been considered, and risk assessment methodology developed by the U.S. Environmental Protection Agency (U.S. EPA) has been used.
