永久性化学物质PFAS因其防水防油特性被广泛用于不粘锅具和灭火泡沫等产品中，但这一应用导致了严重的环境和健康污染。1美国89%的人口血液中PFAS含量超过2纳摩尔/毫升，其中9%的人群超过了20纳摩尔/毫升的风险水平。1PFAS与生殖、发育、癌症和免疫系统问题相关联。1
为应对这一挑战，科学家正在开发多种清除方案。1电化学降解技术已在测试中取得进展，能破坏超过90%的PFAS质量，目前已由工程咨询公司AECOM获得许可应用。1此外，泡沫分馏等捕获方法也正在探索中。1然而，现存超过12000种PFAS化合物，而清理研究目前仅关注其中少数几种。1
在政策层面，多地已采取行动限制PFAS产品的使用。1美国环保局2010年和2015年推行的全氟辛酸自愿计划成功将水排放减少了95%。1明尼苏达州、缅因州和新墨西哥州相继通过了针对烹饪器具和牙线等产品的PFAS禁令。1
Per- and polyfluoroalkyl substances, commonly known as PFAS, have become pervasive environmental and health contaminants due to their widespread use in non-stick products and firefighting foams 1. The chemicals have been linked to reproductive, developmental, cancer, and immune system problems 1. A significant portion of the U.S. population carries detectable levels of these substances: 89% of Americans have PFAS concentrations exceeding 2 nanomoles per milliliter in their blood, while 9% surpass the 20 nanomoles per milliliter risk threshold 1.
Researchers are developing diverse approaches to address the contamination challenge. Destructive methods, including electrochemical degradation, show promise in laboratory settings—this technology has destroyed more than 90% of PFAS mass during testing and has been licensed by engineering consulting firm AECOM 1. Capture-based techniques such as foam fractionation represent an alternative removal strategy 1. The scope of the challenge is substantial, as more than 12,000 PFAS compounds currently exist, yet cleanup research has focused on only a small subset of these 1.
Policy measures are complementing technological efforts. The EPA's voluntary programs for perfluorooctanoic acid (PFOA) conducted between 2010 and 2015 achieved a 95% reduction in water discharge 1. Several states have enacted restrictions on PFAS-containing products: Minnesota, Maine, and New Mexico have all passed bans targeting items such as cookware and dental floss 1.
