摘　　要：目的 探讨H江水源水及其出厂水中非挥发性有机物的致突变性与其化学组分的关系。方法 应用大孔树脂吸附浓集水中有机物的技术,结合Ames致突变试验与色谱-质谱（GC/MS）联机分析方法,对H江武汉段水源水及其所制成的自来水中非挥发性有机物的致突变性及其化学组分进行了检测与比较。结果 在加与不加体外代谢活化系统（S9）的条件下,H江水源水及出厂水中非挥发性有机物对TA98与TA100菌株均具明显地致突变性;GC/MS联机分析鉴定水源水及其出厂水非挥发性有机物中有邻苯二甲酸酯（酞酸酯）等26种化合物。出厂水中非挥发性有机物的致突变性强度与有机化学物的种类均分别高于、多于水源水。结论 水源水经水厂处理后可生成一些新的有机物,由此使得出厂水中非挥发性有机物的致突变性增强。Objective To study the relationship between the mutagenicities of nonvolatile organic compounds (NVOCs) extracted from source water of H river and the finished water and the components of these nonvolatile organic compounds. Methods The mutagenicity and the components of thd NVOCs extracted from water samples collected from source water of Wuhan section of H river and finished water were determined by Ames test and GC/ MS method. Results The NVOCs extracted from source water of H river and finished water showed significant mutagenicity to strains of TA98 and TA100 with or without S9 mixture. 26 NVOCs including phthalate, etc. were detected and identified in water samples collected from source water and finished water by GC/ MS method. Stronger mutagenicity of NVOCs and more kinds of NVOCs were found in finished water compared with those in source water. Conclusion Some new kinds of organic compounds were formed in finished water after the treatment of source water, so the mutagenicity of NVOCs in finished water increased.
