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

太湖是长三角主要城市最重要的饮用水源地。近年来太湖内分泌干扰物(endocrine disrollments, EDCs)污染呈上升趋势,准确测定是预测其健康风险和制定相应控制措施的重要指南。使用薄膜扩散梯度技术 (DGT) 监测水中的有机污染物由于比抓取采样方法更准确和方便而备受关注。在这项研究中，一种新型环糊精聚合物 (CDP) 通过简单和绿色的方法在水中合成，被用作结合凝胶的吸附剂。以四种内分泌干扰物 (EDC)、双酚 A (BPA)、17α-炔雌醇 (EE2)、17β-雌二醇 (E2) 和雌三醇 (E3) 作为模型来确定扩散系数 (4.68 × 10⁻⁶ , 3.38 × 10 ⁻⁶ , 3.34 × 10 ⁻⁶和 4.31 × 10 ⁻⁶  cm ² /s) 并测试 DGT 的性能，如吸附容量和部署时间（1-5 天）。采用组装的 CDP-DGT 测定模拟水环境中的四种 EDC（pH 值 3–9，离子强度 (IS) 0.001–0.5 M，溶解有机物 (DOM) 0–20 mg/L）。CDP-DGT采样能力在九乡河得到验证，并开展原位大范围野外应用太湖流域的内分泌干扰物采样。结果表明，太湖及其主要河流的EDCs总浓度范围和雌二醇当量浓度（EEQ）分别为2.78 ng/L至11.08 ng/L和2.62 ng/L至10.91 ng/L。该区域所有采样点的风险商数（risk quotients，RQs）均大于1，表明EDCs对该区域的水生生物构成严重威胁。因此，应进一步加强对太湖流域EDCs的监测。
