Taihu Lake is the most important drinking water source of major cities in Yangtze River Delta. The pollution endocrine disruptors (EDCs)in has been increasing recently, accurate determination an guide for predicting its health risks and developing appropriate controls. Monitoring organic pollutants using diffusive gradient thin film technique (DGT) attracted much attention due to more accuracy convenience than grab sampling methods. In this study, a novel cyclodextrin polymer (CDP) synthesized by simple green method was taken as adsorbent binding gel. Four endocrine-disrupting chemicals (EDCs), bisphenol A (BPA), 17α-ethinylestradiol (EE2), 17β-estradiol (E2), estriol (E3), were models determine diffusion coefficients (4.68×10-6, 3.38×10-6, 3.34×10-6 4.31×10-6 cm2/s) test performance DGT, such adsorption capacity deployment time (1-5 day). assembled CDP-DGT adopted four EDCs simulated environment (3-9 pH, 0.001-0.5M ionic strength (IS), dissolved matter (DOM) 0-20mg/L). ability verified Jiuxiang carried out large-scale field application situ basin. results show that total concentration range estradiol equivalent concentrations (EEQ) main rivers are 2.78 ng/L 11.08 2.62 10.91 ng/L, respectively. risk quotients (RQs) all sites region greater 1, indicating pose serious threat aquatic organisms area. Therefore, monitoring basin should be further strengthened.
