Wastewater treatment plants (WWTPs)-derived national discharge loads of perfluorinated compounds (PFCs)

► We measured PFCs concentrations in influent, effluent, and sludge in WWTPs. ► PFCs were greater in industrial wastewater than in domestic wastewater. ► Total WWTP-derived national discharge loads were calculated as 0.04-0.61 ton/year for individual PFCs. ► 63% of perfluorooctanoate from domestic wastewater, and 75% of perfluorooctanesulfonate from industrial wastewater.
