摘　　要：应用Ames试验与色质联机 (GC/MS)分析相结合的方法 ,对武汉东湖源水及自来水中非挥发性有机物的致突变性及化学组分进行了比较。试验结果表明 ,无论投加体外代谢活化系统 (S9)与否 ,自来水中非挥发性有机物对TA98与TA10 0菌株均具明显的致突变性 ,而源水为阴性结果 ;GC/MS分析鉴定出源水及自来水的非挥发性有机物中含有邻苯二甲酸酯 (酞酸酯 )等 2 0余种化合物。Based on the Ames test in combination with gas chromatography/mass spectroscopy (GC/MS) analysis, examination was made for the mutagenicity and chemical composition of nonvolatile organic compounds (NOCs) in source water from Donghu Lake and water supply. The results showed that whether the exotic metabolic activity system (S9) is added, the NOCs from water supply exhibit obvious mutagenicity to the bacterial strain TA98 and TA100 and the mutagenicity of NOCs from source water cannot be detected. By using GC/MS analysis, more than 20 chemical compositions of NOCs including phthalic ester are identified both in source water and water supply.
