The occurrence of estrogenic compounds in Yeongsan and Seomjin rivers in Korea was monitored during 2005-2008. Target compounds were 4-nonylphenol (NP), 4-tert octylphenol (OP), bisphenol A (BPA), estrone (E1), 17β-estradiol (E2), 17α-ethynylestradiol (EE2) and genistein (Gen). Water samples were pretreated and analyzed by liquid-liquid extraction (LLE) and gas chromatography/mass spectrometry (GC/MS), respectively. The effects of treatment processes on estrogenicity were evaluated by examining estradiol equivalent (EEQ) concentrations in influents and effluents of sewage treatment plants (STPs) located along the rivers. The results showed that phenolic groups of estrogenic compounds (i.e., NP, OP and BPA) were frequently found in surface water. The concentrations, followed the order of NP >> BPA > OP, were smaller than those reported by previous studies in Korea. Natural hormones (E2, E1) were also determined at several ng/L levels in water samples. Synthetic hormone (EE2) was rarely found in surface water although it was detected in the influents of the monitored STPs. Meanwhile, the phytoestrogen (i.e., Gen) were smaller than limit of detection in most samples. This study provided a general view of the distribution and transport of estrogenic compounds in Korean surface water.
