Endocrine Disrupting Compounds from the Source Water of the Huai River (Huainan City), China

摘要

Abstract 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 ?
