Different homologues of C4 to C8 perfluoroalkyl carboxylates (PFCAs) and perfluoroalkyl sulfonates (PFASs) were detected in German surface waters, bank filtrates, artificially recharged groundwaters, and drinking waters. If no point sources are located nearby, the typically measured levels are in the low ng/L range. In the presence of point sources, such as a fluorochemical production site, a leaching agricultural fertilizer contaminated with PFCAs and PFASs, or drained PFC containing fire-fighting foams, much higher concentrations in the microg/L range occur. This situation is similar in Germany and other countries.
在德国的地表水、岸边渗滤液、人工补给的地下水和饮用水中检测到了全氟烷基羧酸盐(PFCA)和全氟烷基磺酸盐(PFAS)的不同同系物,其碳链长度从C4到C8。如果附近没有点源,通常测量到的浓度处于纳克/升的低水平范围。当存在点源时,如氟化物生产场地、被PFCA和PFAS污染的浸出型农用肥料或排放含PF的消防泡沫时,会出现微克/升范围内高得多的浓度。德国和其他国家的情况类似。
