摘要/Abstract

摘要： 从黄浦江流域采集了15 份冬季水体和悬浮物样品, 利用液相色谱-质谱联用技术(liquid chromatography-mass spectroscopy-mass spectroscopy, LC-MS-MS)分析了水体和悬浮物样品中壬基酚(nonylphenol, NP)、4-t-辛基酚(4-t-octylphenol, 4-t-OP)、4-t-丁基酚(4-t-butylphenol, 4-t-BP)和双酚A(bisphenol A, BPA)的质量浓度分布. 结果表明, 黄浦江流域水体和悬浮物样品中的酚类环境激素质量浓度范围分别为47.25356.43 ng/L 和2.2948.50 mg/g, 平均值分别为167.69 ng/L 和20.81 mg/g. 因子分析结果说明, 黄浦江水域中酚类环境激素主要以NP, 4-t-OP 和BPA 为主, 局部水域伴有4-t-BP 的高残留. 生态风险评价结果显示, 黄浦江流域水体中的酚类环境激素的危害商数均小于1, 表明不存在严重和频发的酚类环境激素生态毒理风险, 但其生物富集效应不容忽视.

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.
