| Research Abstract |
The occurrence, concentrations and environmental risks of bisphenol analogues, a group of bisphenol A (BPA, CAS# 80-05-7) alternatives, were investigated in the aquatic environment. The high concentrations of bisphenol S (BPS, CAS# 80-09-1) and BPS-monoP (CAS# 95235-30-6) were ubiquitously detected in aqueous and sediment samples. The amount of BPS discharge was calculated as 7,200 kg per year, and the paper manufacturing plants may be a major source of BPS and BPS-monoP into the aquatic environment. The MEC/PNEC ratios of BPA, BPS and BPS-monoP were above 1.0 in several locations examined in this study, which implies their potential risks in the ecosystems.
