Simultaneous determination of 4-tert-octylphenol,4-nonylphenol and bisphenol A in Guanting Reservoir using gas chromatog

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. 作 者： JIN Xing-long    HUANG Guo-lan    JIANG Gui-bin    ZHOU Qun-fang    LIU Jing-fu   作者单位： JIN Xing-long,HUANG Guo-lan(College of Environmental Science and Engineering,Nankai University,Tianjin 300071,China)
