[Research on the establishment of standard limits for perfluorooctanoic acid and perfluorooctane sulfonate in the "Standards for Drinking Water Quality（GB5749-2022）"in China].

Perfluorinated compounds, especially Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are widely detected in water environments in China. Considering the potential health risks of drinking water exposure routes, PFOA and PFOS have been added to the water quality reference index of the newly issued "Standards for Drinking Water Quality (GB5749-2022)", with limit values of 40 and 80 ng/L, respectively. This study analyzed and discussed the relevant technical contents for determining the limits of the hygiene standard, including the environmental existence level and exposure status of PFOA and PFOS, health effects, derivation of safety reference values, and determination of hygiene standard limits. It also proposed prospects for the future direction of formulating drinking water standards.全氟化合物尤其是全氟辛酸（PFOA）与全氟辛烷磺酸（PFOS）在我国水环境中广泛检出。考虑到饮用水暴露途径的潜在健康风险，我国新颁布的《生活饮用水卫生标准》（GB 5749-2022）中的水质参考指标增加了PFOA和PFOS指标，限值分别为40和80 ng/L。本研究对确定该卫生标准限值的相关技术内容进行了分析和讨论，包括PFOA与PFOS的环境存在水平和暴露状况、健康效应、安全基准值的推导和卫生标准限值的确定等，并提出了未来饮用水标准制定方向的展望。.
