Abstract

The sorption and the degradation capacity of natural estrogens in freshwater environmental system in Japan were performed. Batch experiments were examined in water-sediment suspensions using six layers of sediment under aerobic and anaerobic conditions. The results indicated that the water-sediment partition coefficient of E1 (K_d^E1) was higher than E2 (K_d^E2). The degradation rate of E1 (k_E1) was smaller than E2 (k_E2). Under aerobic and anaerobic conditions, E1 was formed from E2. The degradation rate of E2 (k_E2) from the surface to bottom of sediment layers was estimated fell in the range from 0.114 to 0.026 h^-1and 0.05 to 0.014 h^-1under aerobic and anaerobic conditions, respectively.
