摘　　要：全氟烷基物质(per-and polyf luoroalkyl substances,PFAS)是一类典型的持久性有机污染物,在世界范围内的环境介质中和人体内常被检出。粤港澳大湾区作为人口稠密的大都市区,政府对大湾区的生态文明建设给予了高度重视,并且实行了严格的环境保护制度。通过综述大湾区内PFAS在各类环境介质以及人体中的污染现状,并与世界范围内的污染状况进行对比,发现大湾区室内空气的PFAS污染比欧洲及加拿大地区严重,并且大湾区某些PFAS存在潜在的生态风险与人体健康风险。调查更全面的大湾区PFAS的污染数据,探索更有效的方法降低PFAS对人体健康与生态环境的影响将是大湾区PFAS污染治理的重点研究方向。Background,aim,and scope Per-and polyf luoroalkyl substances(PFAS)are a class of typical persistent organic pollutants that are frequently detected in various environmental matrices and in the human body globally.The Guangdong-Hong Kong-Macao Greater Bay Area(Greater Bay Area),known for its dense population,rapid urbanization,and industrial activities,presents a critical need to understand the extent of PFAS contamination and its potential impacts on both the ecosystem and public health.This paper aims to provide a comprehensive overview of the contamination characteristics of PFAS within the Greater Bay Area.Materials and methods This paper provides a comprehensive review of the pollution status of PFAS in the Guangdong-Hong Kong-Macao Greater Bay Area,and evaluates the environmental exposure and potential human health risks associated with specific PFAS.Results The concentrations of PFOA,PFOS,PFBA,and PFBS in indoor dust within the Greater Bay Area were significantly higher compared to those in Europe and Canada.Although the risk quotient(RQ)values for PFOA,PFBA,and PFBS are less than one,indicating a lower risk,the RQ value for PFOS is notably higher,which may suggest a more substantial risk to human health in the region.Discussion The contamination of indoor dust in the Greater Bay Area is relatively severe on a global scale.In the aquatic environment of the Greater Bay Area,PFOS poses significant ecological risks.The elevated concentrations of PFAS observed in the residents of the Greater Bay Area are potentially associated with increased environmental pollution,and thus,further investigation and validation are warranted to elucidate the specific mechanisms behind this correlation.Additionally,environmental exposure to specific PFAS may pose a risk to human health in the Greater Bay Area.Conclusions Several PFAS present potential human health risks and serious aquatic ecological risks in Greater Bay Area.Recommendations and perspectives Investigating more comprehensive PFAS pollution data and exploring more
