Abstract: The partition coefficient (K_d) and organic carbon normalized partition coefficient (K_oc) of bisphenol A (BPA) and 17β-estradiol (E2) between the sediments and water were calculated based on the concentration of BPA and E2 in the natural riverine water. Batch experiments with field-measured concentration levels were performed to investigate distribution behavior of BPA and E2 in the sediment-water interface. The results showed that lg K_d (1.40) and lg K_oc (3.51) of BPA derived from batch experiments were in the range of lg K_d (1.63-2.84) and lg K_oc (2.66-4.66) obtained from field-based measurement in natural aquatic environment. The lg K_d (1.10) and lg K_oc (3.51) values of E2 originated from batch experiments were lower than those from field-based measurement, indicating that the results from batch experiments could not properly describe distribution behavior of E2 in the natural environment to some extent. Organic matter in sediment had a positive correlation with sorption capacity of BPA onto sediment, whereas insignificant impact on sorption behavior of E2.
