摘要: Steroid hormone Endocrine Disrupting Compounds (EDCs) (natural estrogens (17-β-estradiol (E2), estrone (E1), estriol (E3), synthetic estrogen (17-α-ethinylestradiol (EE2)), natural androgen (testosterone) (tes) and progestogen (progesterone) (pro)) at an activated sludge wastewater works (WWW), were quantitated using Enzyme-linked immunosorbent assay (ELISA). The steroid profile in the adjacent surface water was also determined. Pro most abundant (41%, 408 ng/L) influent, followed by tes (35%, 343 E2 (12%, 119 ng/L). E1 23 effluent, (30%, 20 (17%, 11 Chemical removal efficiencies of hormones WWW averaged 92%. High efficiency observed for pro (98% ± 2) (96% 1), compared to (72-100%) (90% 3), with biodegradation being major route tes. lowest is spring (65%), maximum winter (95%). Natural (E2, E1) (EE2) contributors influent (E2 = 69%) effluent 73%) estrogenic potency. potency 85% (range: 73-100). Risk assessment present water, indicated that EE2 pose highest risk human health fish. found be much more resistant biodegradation, E2, water. Estrone, as breakdown product wastewater, appears suitable indicator EDCs. study suggests a battery tests: quantitative chemical assay, bioassay activity methods, collectively, are preferred order make meaningful, accurate conclusions regarding potential adverse effects EDCs treated or aquatic environment, health, wildlife systems.
