Abstract
Occurrence and distribution of eight selected endocrinedisrupting compounds EDCs including estrone E1 17αethinylestradiol EE2 17αestradiol αE2 17βestradiol βE2 estriol E3 bisphenol A BPA 4nonylphenol NP and 4octylphenol OP were investigated in surface water and sediments of the Three Gorges Reservoir region TGRR The mean concentrations of E1 αE2 βE2 E3 EE2 BPA NP and OP were 103 33 37 172 78 266 108 and 323 ng L−1 respectively in surface water and 26 41 77 24 118 174 50 and 53 ng g−1 dry weight dw respectively in sediments BPA NP and OP were the main EDCs in both media Distributions of EDCs in surface water and sediments varied significantly in space but not synchronously The higher EDCs abundance was found in the upstream water of the TGRR EDCs concentrations in sediments had no correlations with those in water and the total organic carbon content in sediments EDCs presented low to high risks in the water and steroidal estrogens were the main contributors to the total estrogenic activitiesThis project was supported in part by Natural Science Key Foundation of Hubei Province of China NO 2014CFA114 Funding Project of SinoAfrica Joint Research Center Chinese Academy of Sciences Y623321K01 and the Hundred Talents Program of the Chinese Academy of Sciences Y329671K01
