全氟烷基和多氟烷基物质 (PFAS) 存在于世界各地的水生系统、动植物群中。这些潜在有害化合物在瑞典也经常被检测到，并已对公共饮用水供应造成严重问题，即由于原水和生产的饮用水中 PFAS 浓度较高，一些水井不得不关闭。尽管目前正在进行监测，但对瑞典 PFAS 发生情况的了解仍然相当少。这项工作描述了 PFAS 进入瑞典饮用水供应的潜在来源，并比较了该国原水中和饮用水中 PFAS 的不同出现情况。此外，还介绍了监测历史、法律状况和采取的补救措施。最后，讨论了瑞典未来的挑战和前进的道路。
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found in aquatic systems, flora, and fauna worldwide. These potentially harmful compounds are also frequently detected in Sweden and have already resulted in severe problems for public drinking water supply, i.e., some wells had to be closed due to high PFAS concentrations both in raw water and produced drinking water. Knowledge on PFAS occurrence in Sweden is still quite low, although monitoring is currently ongoing. This work describes potential sources for PFASs to enter the drinking water supply in Sweden and compares different occurrences of PFASs in raw and drinking water in the country. Moreover, the monitoring history, the legal situation, and remediation actions taken are presented. Finally, future challenges and the way forward in Sweden are discussed.
