The occurrence and environmental risk of eight endocrine disrupting compounds (EDCs), namely dimethyl phthalate (DMP), diethyl phthalate (DEP), benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), nonyl phenol (NP), bisphenol A (BPA), 17α-ethinylestradiol (EE2) and estrone (E1), from four water sources (Pingshantou, Wanfenggang, Shisi, and Shiyi) of Huai River (Huainan section) were investigated in this study. Except for DMP only found in Pingshantou, all of the selected EDCs existed widely in the source water. DMP, DEP, BBP, DBP, NP, BPA, EE2, and E1 had the ranges of nd (cannot be detected)-130 ng/L, 25-310, 76-1351, 431-1299, 215-627, 23-107, nd-0.174, and 0.143-0.334 ng/L, respectively. Therefore, the studied water sources were associated with notable levels of EDCs, wherein the concentrations of BBP, DBP, and NP were much higher than the other five chemicals. The selected EDCs appeared to be higher in upstream than in downstream (p < 0.05) for each water source, suggesting that EDCs were subjected to a decreasing with water flow. Correlation analysis suggests that DEP-BP-DBP, NP-BPA, and EE2-E1 might have the same sources, respectively; and the source of NP, EE2, and E1 was different from that of BBP, BEP and BBP, and DEP, respectively. It was observed that both the TAS (total ambient severity) and RQ (risk quotient) were less than 1, indicating that EDCs in Huai River (Huainan section) posed little or no thread to the health of local inhabitants and ecological environmental.
本研究调查了淮河（淮南段）四个水源（平山头、万丰港、十四和十一）中八种内分泌干扰化合物（EDCs），即邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸丁基苄基酯（BBP）、邻苯二甲酸二丁酯（DBP）、壬基酚（NP）、双酚 A（BPA）、17α-乙炔雌二醇（EE2）和雌酮（E1）的存在和环境风险。除了仅在平山头发现的 DMP 外，所有选定的 EDCs 都广泛存在于水源水中。DMP、DEP、BBP、DBP、NP、BPA、EE2 和 E1 的浓度范围分别为 nd（未检出）-130ng/L、25-310ng/L、76-1351ng/L、431-1299ng/L、215-627ng/L、23-107ng/L、nd-0.174ng/L 和 0.143-0.334ng/L。因此，研究的水源与显著水平的 EDCs 有关，其中 BBP、DBP 和 NP 的浓度明显高于其他五种化学物质。对于每个水源，上游的选定 EDCs 似乎高于下游（p<0.05），这表明 EDCs 随着水流而减少。相关性分析表明，DEP-BP-DBP、NP-BPA 和 EE2-E1 可能分别具有相同的来源；而 NP、EE2 和 E1 的来源与 BBP、BEP 和 BBP、DEP 不同。观察到 TAS（总环境严重程度）和 RQ（风险商）均小于 1，这表明淮河（淮南段）中的 EDCs 对当地居民和生态环境的健康构成的威胁较小或没有。
