氟化物是持久性污染物，分布在全球空气、水、沉积物和生物群中。废水处理厂 (WWTP) 在减少城市污染物向水生和陆地环境的排放方面发挥着重要作用。然而，由于污水处理厂是含氟化合物的点源，因此在更大的流域背景下了解它们对含氟化合物负担的贡献非常重要。为此，在 1 周的时间内，测量了向瑞士格拉特河排放污水的 7 个污水处理厂的 11 种含氟化合物的质量流量，并与格拉特河内测得的质量流量进行了比较。总体而言，废水处理过程中含氟化合物没有得到有效去除。污水处理厂和格拉特河水的出水以全氟辛烷磺酸盐为主，在所有样品中均检测到，其次是全氟己烷磺酸盐和全氟辛酸盐。研究发现，污水处理厂排放的含氟化合物的质量流量在 35 公里的格拉特河内保持不变，这表明污水处理厂的输入量是累加性的，格拉特河内的去除量并不显着。人均氟化物排放量是根据所研究的污水处理厂所服务的人口计算得出的；确定的值还考虑了格赖芬湖 (Greifensee) 的氟化物含量，该湖是格拉特河源头的一个湖泊，也接收经过处理的废水。
Fluorochemicals are persistent contaminants that are globally distributed in air, water, sediments, and biota. Wastewater treatment plants (WWTPs) play an important role in mitigating pollutant releases from municipalities to aquatic and terrestrial environments. However, because WWTPs are point sources of fluorochemicals, it is important to understand their contribution to fluorochemical burdens in the greater context of watersheds. To this end, over a 1 week period, the mass flows of 11 fluorochemicals from seven WWTPs that discharge effluent into the Glatt River in Switzerland were measured and compared to the measured mass flows within the Glatt River. Overall, the fluorochemicals were not removed efficiently during wastewater treatment. Effluents from WWTPs and Glatt River water were dominated by perfluorooctane sulfonate, which was detected in all samples, followed by perfluorohexane sulfonate and perfluorooctanoate. The mass flows of fluorochemicals emanating from WWTPs were found to be conserved within the 35 km Glatt River, which indicates that input from the WWTPs is additive and that removal within the Glatt River is not significant. Per capita discharges of fluorochemicals were calculated from the populations served by the WWTPs studied; the values determined also account for the fluorochemical content of Lake Greifen (Greifensee), which is a lake at the headwaters of the Glatt River that also receives treated wastewater.
