抚仙湖有机污染物化学背景值及人淋巴细胞体外致突变性评定

The Background Content of Organic Chemicals and Mutagenicity Assessment of Human Lymphocytes In vitro of Water From Fuxian Lake

摘要: 用XAD-2树脂提取抚仙湖7个采样点的有机物质水样提取物，用气相色谱/质谱(GC/MS)进行分析。在每种水样品中发现有上百种有机污染物。提取物用培养的人淋巴细胞系姐妹染色单体交换(SCE)试验作致突变潜力检查。结果显示，仅入湖口水样在高浓度组(0.0625 L/mL)诱发SCE明显增加。

Abstract: The organic substance in test sample were extracted by XAD-2,and the extracts of water sample in seven localities from lake water sample of Fuxian Lake were analyzed by gas chromatography-mass spectrometry (GC/MS).Over hundred organic pollutants were discovered in every water sample.The extracts were examined for mutagenic potential by the sister-chromatid exchanges (SCEs) test in cultured human lymphocyte.According to our results,the water sample of Ruhukou only at higher concentration group (0.0625 L/mL) induced a significant increase for SCE.
