Forty-seven surface water samples were collected from the main stream and 22 tributaries in area of the Three Gorges Reservoir, 15 phenolic compounds in these samples were analyzed using GC/MS. The results showed that the concentrations of phenolic compounds in the samples from the main stream and tributaries were 52.47 ng x L(-1) and 87.99 ng x L(-1), respectively. The concentrations of non-chlorinated phenols were higher than those of chlorinated phenols in the main stream and tributaries, and so the non-chlorinated phenols were the predominant compounds in these surface water samples. Phenol, o-cresol and 2-nitrophenol were the predominant compounds accounted for 79.1%, 3.7% and 3.6% in the samples from the main stream, respectively. Phenol, o-cresol, 2,6-dichlorophenol and 2-nitrophenol were the main compounds accounted for 77.5%, 5.4%, 3.8% and 2.2% in the samples from the tributaries, respectively. As compared the concentrations of phenol and 2-nitrophenol with the standard limits in The National Environmental Health Risk List, the levels of phenol and 2-nitrophenol were much lower than the standard limits, suggesting negligible risk of phenol and 2-nitrophenol in these samples.
从三峡水库区域的干流和22条支流采集了47个地表水样本，采用气相色谱/质谱联用仪分析了这些样本中的15种酚类化合物。结果表明，干流和支流样本中酚类化合物的浓度分别为52.47 ng·L⁻¹和87.99 ng·L⁻¹。干流和支流中非氯酚的浓度高于氯酚，因此非氯酚是这些地表水样本中的主要化合物。苯酚、邻甲酚和2-硝基苯酚是干流样本中的主要化合物，分别占79.1%、3.7%和3.6%。苯酚、邻甲酚、2,6-二氯苯酚和2-硝基苯酚是支流样本中的主要化合物，分别占77.5%、5.4%、3.8%和2.2%。将苯酚和2-硝基苯酚的浓度与《国家环境卫生风险清单》中的标准限值进行比较，苯酚和2-硝基苯酚的含量远低于标准限值，表明这些样本中苯酚和2-硝基苯酚的风险可忽略不计。
