OCCURRENCE OF PERFLUOROOCTANE SULFONATE (PFOS) AND PERFLUOROOCTANOIC ACID (PFOA) IN A WASTEWATER TREATMENT PLANT OF HARBIN, CHINA
Perfluorinated chemicals (PFCs), especially perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are ubiquitous distributed in the aquatic environment. In this study, grab water samples from influent, primary effluent, secondary effluent were collected for five days in a full-scale wastewater treatment plant (WWTP) of Harbin, a city in northeastern China, which receives almost 100％ domestic wastewater, and the concentrations of PFOS and PFOA of the samples were measured. While PFOA was not detected in all samples, PFOS was observed at low concentrations with a mean (in ng/L) of 3.33 (±1.71) in influent, 7.98 (±2.91) in primary effluent, and 3.02 (±0.94) in secondary effluent, showing the limitation of current treatment processes in removing PFOS in wastewater.
