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.
选取了包括氯贝酸（CA）、双氯芬酸（DFC）、布洛芬（IBP）、酮洛芬（KEP）和萘普生（NPX）在内的5种持久性有机污染物作为目标化合物，以研究它们在上海某污水处理厂（WWTP）中的存在情况和去除效率。此外，还研究了它们在接收河水的污水处理厂中的分布及潜在毒理学风险。结果表明，在污水处理厂进水口检测到了所有目标化合物，这表明生活污水排放是污水处理厂中持久性有机污染物的一个重要来源。在污水处理厂中发现这些持久性有机污染物的去除效率较低，且消除的主要机制是生物降解。所选的5种持久性有机污染物在河流中的分布模式与污水处理厂出水相似，这表明污水处理厂出水是受纳水体中持久性有机污染物的主要来源。风险评估表明，双氯芬酸构成高风险，而酮洛芬、萘普生、氯贝酸和布洛芬对接收河流中的生物群显示低风险。
