Abstract: Transformation and distribution characteristics of phenolic environmental hormones in 15 winter water and suspended solids samples from Huangpu River were studied. Pollution levels, spatial distributions of nonylphenol (NP), 4-t-octylphenol (4-t-OP), 4-tbutylphenol (4-t-BP) and bisphenol A (BPA) in water and suspended solids were analyzed by liquid chromatography-mass spectroscopy-mass spectroscopy (LC-MS-MS). The results showed that concentration of the above 4 phenolic environmental hormones in water and suspended solids were 167.69 ng/L with a range of 47.25356.43 ng/L, and 20.81 mg/g with a range of 2.2948.50 mg/g, respectively. The factor analysis showed that the principal pollutants were NP, 4-t-OP and BPA, with a high concentration of 4-t-BP in some
basins. Ecological risk assessment showed that hazard quotient were below 1 in the above 4 phenolic environmental hormones, and no ecological risk was found. Special attention should be paid to the potential hazard caused by algae accumulation.
