“…Various industries, like textile, 1,2 paint, 3,4 pharmaceutical, 5 and food, 6 are the direct contributors of pollutants like dyes, 7 heavy metal ions 8,9 and other organic pollutants 10 to water. These pollutants are toxic and cause severe health problems in human beings and also seriously affect aquatic life.…”

“…Ecological risks of PPCPs in surface waters were assessed by use of a methodology developed within the NORMAN Association [33] and previous studies [8,[33][34][35][36]. Chronic, sublethal, risk quotients (RQ) were calculated by dividing measured concentration of individual chemicals in waters by the predicted no effect concentration (PNEC; Equation 1).…”

“…There were differences in the number, types and concentrations of PPCPs detected in waters of the two lakes. This result might be caused by several factors, including differences in use and release, removal efficiency of the WWTPs, degradation rate, temperature and dilution of receiving waters [8,41]. Compared with Baiyangdian Lake, Tai Lake possess richer water resources and higher temperature that could result in PPCPs being diluted and more quickly being degraded.…”

Background: Management of pharmaceuticals and personal care products (PPCPs) in the environment has become a social issue. In the present study, concentrations of 140 PPCPs at 20 sites in Baiyangdian Lake and Tai Lake from 2016 to 2017 were analyzed by Ultra Performance Liquid Chromatography Mass Spectrometer (UPLC-MS). Risk quotients (RQ) were calculated for each detected chemical at all sites and prioritization indices (PI), based on maximum RQ, were calculated. To assess the risk of chemicals that identified high priority (PI>1), a more accurate method of joint probability curves (JPCs) was applied. Results: A total of 42 PPCPs were identified and quantified detected in the two lakes, with maximum concentrations ranged from 0.04 to 889 ng/L. Among these, seven PPCPs were identified as high or moderate risk pollutants for at least one site, 3 in Tai Lake and 5 in Baiyangdian Lake. Carbamazepine posed significant ecological risk at all 20 sites, such that more attention should be paid to that drug. Based on results of the JPCs, sulfamethoxazole, caffeine, diethyltoluamide, and carbamazepine were categorized as high or intermediate risks. Conclusion: Occurrences and distributions of PPCPs were different in the two lakes. Multiple-level risk assessment from simple to more complex was appropriate in chemical risk management.

Emerging pollutants, known for their high toxicity, pose significant risks to human health and the environment. However, the identification of these pollutants is difficult and costly due to their low concentration and complex composition. Here, a cost‐effective and scalable identification method is demonstrated to rapidly concentrate and detect emerging pollutants at ultra‐low concentrations. The approach takes advantage of responsive autonomous propulsion R‐Fe3O4@Au@β‐CD‐EG‐PF127 (RAP) nanomotors driven by magnetism, to significantly enhance the efficiency of pollutant adsorption in large‐scale water. Owing to the fast driving capability and multi‐interaction mechanism, nanomotors can effectively capture trace concentrations of emerging pollutants, achieving a capture efficiency of over 90%, while also ensuring that all captured pollutants fall within the enhanced electromagnetic field range of the nanomotors. This leads to highly sensitive surface‐enhanced Raman scattering (SERS) signals with detection limits as low as 10−10 m. Contaminated nanomotors showcase significant self‐cleaning capabilities that can be activated through temperature variations, resulting in a substantial reduction in detection expenses. Even after undergoing cyclic experiments, the nanomotors consistently exhibit remarkable capture efficiency and outstanding SERS sensitivity. This work can provide a scalable and practical technical solution to eliminate and monitor the transport of emerging pollutants in the environment.
