title: [Occurrence and risk assessment of five selected PPCPs in municipal wastewater treatment plant and the receiving water].
abstract: Five PPCPs, including clofibric acid (CA), diclofenac (DFC), ibuprofen (IBP), ketoprofen (KEP), and naproxen (NPX) were selected as target compounds to investigate their occurrence and removal efficiency in a wastewater treatment plant (WWTP) of Shanghai. Furthermore, their distribution and potential toxicological risk in the WWTP receiving river water were investigated. The results showed that all targets were detected in WWTP influent, suggesting that domestic sewage discharge is an important source of PPCPs to the WWTP. Lower removal efficiency of these PPCPs was found in the WWTP and the main mechanism of elimination was biodegradation. The pattern of five selected PPCPs in the river was similar to that in WWTP effluent, indicating that WWTP effluent was a main source of PPCPs to the receiving water. Risk assessment showed that diclofenac posed a high risk, while ketoprofen, naproxen, clofibric acid and ibuprofen showed low risks to biota in the receiving river.
