Abstract: The degradation of bisphenol A (BPA), 17 β-estradiol (E2), and 17 α-ethynylestradiol (EE2) in river water was investigated. Moreover, the effects of temperature, nutrient salts, easily degraded coexisting organic matter, and the addition of municipal wastewater, were studied. The half-lives of E2 are six days at 20°C and three days at 30°C in river water, respectively. BPA is degraded significantly only in river water spiked with wastewater, and the half-life is from 1 to 2 days. In contrast, EE2 was persistent under all conditions in present study. Estrone (E1), the metabolite of E2, is identified during E2 degradation.
