摘要
全氟和多氟烷基化合物(PFASs)是一类具有抗水、抗油、抗污等良好特性而被广泛使用的化学品。PFASs在环境中具有极强的持久性及稳定性,已经严重威胁到生态环境平衡及人类健康。我国是全球最大的氟化合物制造和消费大国,虽然环境介质中PFASs赋存浓度并不比欧美国家高,但PFASs在我国居民人体内的暴露水平较美国高,对人体免疫、代谢、生殖及心血管系统带来健康威胁,并通过生殖系统影响胎儿发育。欧美发达国家在20年前就开始关注PFASs,并逐步出台了一系列的监管措施,并对饮用水中PFASs的含量设定了推荐值。中国在这方面起步较晚,监管措施有待完善。本文通过总结欧美日等主要发达国家和地区的监管政策,为我国相关部门制定监管措施提供参考。
Per-and polyfluoroalkyl substances(PFASs)are a class of widely used chemicals known for their e xcellent properties such as water-,oil-,and stain-resistance.PFASs exhibit extreme persistence and stability in the environment,posing a severe threat to ecological balance and human health.Although China is the world’s largest p roducer and consumer of fluorinated compounds,the concentration of PFASs in its environmental media is not higher than that in Europe and the United States.However,the exposure levels of PFASs in Chinese residents are higher than those in the United States,posing health threats to the human immune,metabolic,reproductive,and cardiovascular systems,and affecting fetal development through the reproductive system.Developed countries such as those in Europe and the United States began to address PFASs twenty years ago and have gradually introduced a series of regulatory measures,including setting recommended limits for PFASs in drinking water.China has s tarted to focus on this issue later,and its regulatory measures need improvement.This paper summarizes the r egulatory policies in major developed countries and regions,including Europe,the United States,and Japan,to provide references for relevant authorities in China to formulate regulations.
