Per- and polyfluoroalkyl substances (PFAS) have become a growing environmental concern due to their tangible impacts on human health. However, due to the large number of PFAS compounds and the analytical difficulty to identify all of them, there are still some knowledge gaps not only on their impact on human health, but also on how to manage them and achieve their effective degradation. PFAS compounds originate from man-made chemicals that are resistant to degradation because of the presence of the strong carbon-fluorine bonds in their chemical structure. This review consists of two parts. In the first part, the environmental effects of fluorinated compound contamination in water are covered with the objective to highlight how their presence in the environment adversely impacts the human health. In the second part, the focus is put on the different techniques available for the degradation and/or separation of PFAS compounds in different types of waters. Examples of removal/treatment of PFAS present in either surface or ground water are presented.
全氟和多氟烷基物质（PFAS）因其对人类健康的明显影响而成为日益受到关注的环境问题。然而，由于 PFAS 化合物数量众多，且分析识别所有这些化合物具有一定难度，因此不仅在其对人类健康的影响方面，而且在如何管理这些化合物以及实现其有效降解方面，仍存在一些知识空白。PFAS 化合物源自人造化学品，由于其化学结构中存在强碳-氟键，因此具有抗降解性。本综述由两部分组成。第一部分涵盖了水中含氟化合物污染的环境影响，旨在强调其在环境中的存在如何对人类健康产生不利影响。第二部分重点介绍了不同类型水中 PFAS 化合物降解和/或分离的可用技术。介绍了去除/处理地表或地下水中存在的 PFAS 的实例。
