在中国天津海河地表水样品中测定了雌激素污染物 4-叔辛基苯酚 (OP)、4-壬基苯酚 (NP) 和双酚 A (BPA)。使用二氯甲烷通过液-液萃取从 300 ml 酸化水样中提取和浓缩分析物，用三氟乙酸酐衍生化，并通过气相色谱-质谱 (GC-MS) 和选择离子监测 (SIM) 进行定量。在14个采样点采集的样品中，仅1个样品的BPA（8.30 mugl(-1)）和NP（0.55 mugl(-1)）浓度较高。其他样品中OP、NP和BPA的浓度范围分别为18.0-20.2、106-296和19.1-106 ngl(-1)。加标水样中 OP、NP 和 BPA 的回收率均超过 80%。 (C) 2004 Elsevier Ltd. 保留所有权利。
The estrogenic pollutants 4-tert-octylphenol (OP), 4-nonylphenol (NP) and bisphenol A (BPA) were determined in surface water samples from the Haihe River, Tianjin, China. The analytes were extracted and concentrated from 300 ml acidified water samples by liquid-liquid extractions using dichloromethane, derivatized with trifluoroacetic anhydride, and quantified by gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring (SIM). Among the samples collected from 14 sampling sites, only one sample was found to have a relatively high concentration of BPA (8.30 mugl(-1)) and NP (0.55 mugl(-1)). The concentrations of OP, NP and BPA in the other samples were in the range of 18.0-20.2, 106-296 and 19.1-106 ngl(-1), respectively. Recoveries for OP, NP and BPA in the spiked water samples were all over 80%. (C) 2004 Elsevier Ltd. All rights reserved.
