Abstract: The wide occurrence of estrogenic compounds 4-tert-octylphenol,
4-nonylphenol, bisphenol A in surface water of Guanting Reservoir was
successfully determined. The target compounds in water samples were
preconcentrated by liquid-liquid extraction with dichloromethane, derivatized
by trifluoroacetic anhydride, and quantified by gas chromatography-mass
spectrometry (GC-MS) with selected ion monitoring (SIM). In the selected seven
sampling sites (S1–S7), the concentrations of NP in sample S7 were
significantly higher than the other in reservoir. The pollution status in S3
and S7 were much more serious. The concentrations of OP, NP and BPA were in the
range of 44.5–48.8, 221.6–349.6 and 30.2–82.7 ng/L,
respectively. The pollution were mainly inputted from the upper river and
released from sediments in Guanting Reservoir.
