摘要: Fluorochemicals are persistent contaminants that globally distributed in air, water, sediments, and biota. Wastewater treatment plants (WWTPs) play an important role mitigating pollutant releases from municipalities to aquatic terrestrial environments. However, because WWTPs point sources of fluorochemicals, it is understand their contribution fluorochemical burdens the greater context watersheds. To this end, over a 1 week period, mass flows 11 fluorochemicals seven discharge effluent into Glatt River Switzerland were measured compared within River. Overall, not removed efficiently during wastewater treatment. Effluents water dominated by perfluorooctane sulfonate, which was detected all samples, followed perfluorohexane sulfonate perfluorooctanoate. The emanating found be conserved 35 km River, indicates input additive removal significant. Per capita discharges calculated populations served studied; values determined also account for content Lake Greifen (Greifensee), lake at headwaters receives treated wastewater.
