Millions of people around the world may be exposed to drinking water impacted by per- and polyfluoroalkyl substances (PFASs) at levels exceeding local or national advisories. Many studies indicate that the full extent of PFAS contamination is significantly underestimated when only targeted analytical methods are used. Here, we review techniques using bulk organofluorine measurement to quantify the (as of yet) unidentified fraction of PFASs. We discuss advantages and disadvantages of specific approaches and their applicability to water analysis with a focus on the tradeoff between selectivity and inclusivity, and provide suggestions for a path forward to better characterize the wide array of PFASs present in environmental samples.
全球数百万人可能接触到受全氟和多氟烷基物质（PFASs）影响的饮用水，其含量超过了当地或国家的建议水平。许多研究表明，仅使用靶向分析方法时，PFAS污染的全部程度被严重低估。在此，我们回顾了使用总有机氟测量技术来量化PFASs中（截至目前）尚未识别部分的方法。我们讨论了特定方法的优缺点及其在水分析中的适用性，重点关注选择性和包容性之间的权衡，并为更好地表征环境样品中存在的多种PFASs提出了前进方向的建议。
