摘　　要：The presence of trace organic pollutants in the effluent of wastewater treatment plants(WWTPs)poses considerable risks to aquatic organisms and human health.A large-scale survey of 302 trace organic pollutants in the effluent of 46 Chinese WWTPs was conducted to gain an improved understanding of their occurrence and ecological risks.The survey data showed that 216 compounds in 11 chemical classes had been detected in effluents.The sum concentrations of the trace contaminants in effluent ranged from 1,392 ng/L to 35,453 ng/L,with the maximum concentration of perfluoroalkyl substances(PFASs)recorded as the highest(30,573 ng/L),which was markedly less than the reported 185,000 ng/L for the 38 American WWTPs.The concentration of bisphenol analogs(BPs)was up to 4,422 ng/L,significantly higher than those reported in France,Germany,Japan,Korea,and the U.S.PFASs and BPs were the major pollutants,accounting for 59%of the total pollution.Additionally,a total of 119 contaminants were found to have ecological risks(RQ>0.01).Among these,23 contaminants(RQ>1.0)warrant higher attention and should be prioritized for removal.This study lists valuable information for controlling contaminants with higher priority in WWTP effluent in China.
