全氟烷基和多氟烷基物质（PFAS）是一组含有至少一个完全氟化碳原子的人造化学品。PFAS的广泛使用、数量庞大和化学结构多样性，对任何充分保护性的法规、减排和污染场地的补救都构成了挑战。仅对PFAS的一个子集进行监管，导致其被具有类似危害的其他类别成员取代，即令人遗憾的替代品。仅关注全氟烷基酸（PFAAs）的法规是无效的，因为几乎所有其他PFAS都可以在环境中产生PFAAs。在这篇评论中，我们介绍了加州有毒物质控制部（DTSC）将PFAS作为某些消费品中的一个类别进行监管的理由。我们加州DTSC建议对某些含有PFAS类别的消费品进行监管，因为：a）根据加州法规，所有PFAS或其降解、反应或代谢产物都显示出至少一种共同的危害特性，即环境持久性;和B）某些关键的全氟辛烷磺酸是几乎所有其他全氟辛烷磺酸的降解、反应或代谢产物或杂质，显示出额外的危险特性，包括毒性;在环境、人类和生物群中广泛存在;只要PFAS继续使用，就会继续造成不利影响。因此，将PFAS作为一个类别进行监管是合乎逻辑的，必要的和前瞻性的。这一技术立场可能有助于其他监管机构全面解决这一大类具有常见危险特征的化学品。https://doi.org/10.1289/EHP7431
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of manmade chemicals containing at least one fully fluorinated carbon atom. The widespread use, large number, and diverse chemical structures of PFAS pose challenges to any sufficiently protective regulation, emissions reduction, and remediation at contaminated sites. Regulating only a subset of PFAS has led to their replacement with other members of the class with similar hazards, that is, regrettable substitutions. Regulations that focus solely on perfluoroalkyl acids (PFAAs) are ineffective, given that nearly all other PFAS can generate PFAAs in the environment. In this commentary, we present the rationale adopted by the State of California’s Department of Toxic Substances Control (DTSC) for regulating PFAS as a class in certain consumer products. We at the California DTSC propose regulating certain consumer products if they contain any member of the class of PFAS because: a) all PFAS, or their degradation, reaction, or metabolism products, display at least one common hazard trait according to the California Code of Regulations, namely environmental persistence; and b) certain key PFAS that are the degradation, reaction or metabolism products, or impurities of nearly all other PFAS display additional hazard traits, including toxicity; are widespread in the environment, humans, and biota; and will continue to cause adverse impacts for as long as any PFAS continue to be used. Regulating PFAS as a class is thus logical, necessary, and forward-thinking. This technical position may be helpful to other regulatory agencies in comprehensively addressing this large class of chemicals with common hazard traits. https://doi.org/10.1289/EHP7431
