In the present study analytical methodologies were developed for two newly emerging polar perfluorinated alkyl substances (PFAS), namely F3-MSA, and HFPO-DA, in order to assess the occurrence and levels of these PFAS in Dutch and Belgian waters. Two separate methods were needed for analysing F3-MSA and HFPO-DA. A mixed-mode and a reversed phase C18 method were developed for F3-MSA and HFPO-DA, respectively, using a high resolution Orbitrap Fusion mass spectrometer for detection, yielding satisfactory LOD and LOQ results for both analytes. A sample campaign was performed collecting single grab samples from various locations and different stages of the drinking water production chain. Whereas both PFAS were absent in groundwaters, they were found to be present in surface waters, river bank and dune infiltrates, process water, and drinking water, demonstrating the persistence and mobility of both compounds. Based on provisional health-based guideline values (0.15 μg L−1 for HFPO-DA, 11.9 mg L−1 for F3-MSA), the current levels in drinking water from the suppliers involved in this study do not pose a health risk for the human population. Common removal processes used in drinking water production appeared to remove these polar compounds at most partially. At locations close to potential sources of these chemicals (e.g. fluoropolymer production sites), the quality of surface water or river bank filtrate abstracted for production of drinking water must therefore be monitored.

两种新兴全氟烷基物质和相关卤代磺酸的测定及其对饮用水供应链的意义。
在本研究中，开发了两种新出现的极性全氟烷基物质（PFAS）F 3 -MSA和HFPO-DA的分析方法，以评估这些PFAS在荷兰和比利时水域中的存在和水平。需要两种单独的方法来分析F 3 -MSA和HFPO-DA。针对F 3开发了混合模式和反相C18方法-MSA和HFPO-DA分别使用高分辨率Orbitrap Fusion质谱仪进行检测，两种分析物的LOD和LOQ结果均令人满意。开展了一次采样活动，从饮用水生产链的不同位置和不同阶段收集单个抓取样品。尽管两种PFAS都不存在于地下水中，但发现它们存在于地表水，河岸和沙丘渗透物中，工艺用水和饮用水中，证明了这两种化合物的持久性和流动性。基于临时基于健康的指导值（0.15微克大号-1为HFPO-DA，11.9毫克的L -1与F 3-MSA），目前参与本研究的供应商的饮用水水平不会对人类健康构成威胁。饮用水生产中常用的去除方法似乎可以最大程度地去除这些极性化合物。因此，在靠近这些化学物潜在来源的位置（例如，含氟聚合物生产场所），必须监测提取用于生产饮用水的地表水或河岸滤液的质量。
