| 摘 要： | 运用鼠伤寒沙门氏菌 /哺乳动物微粒体酶系 ( Ames)试验 ( DNA)、SOS/Umu试验 (基因 )和蚕豆根尖微核试验(染色体 )对不同季节 (枯、丰、平 )南京市主要水厂的水源水中有机污染物的遗传毒性进行了研究。以 XAD-2树脂为吸附剂 ,丙酮 -甲醇的混合液为洗脱液 ,浓缩水样中有机物 ,并对部分阳性水样进行了有机组分的定性分析 ( GC/MS法 )及其污染源调查。结果发现 ,不同季节水样均有不同程度的遗传毒性检出 ,其中以上元门水厂水质最劣 ;同时通过 GC/MS法分析 ,发现阳性水样中存在有美国 EPA所列的多种优先污染物以及其它黑名单上所属的有毒有害物质 ,应当引起足够的重视

| Abstract: | Genetic toxicity of source water and drinking water in different seasons was researched by Ames test, SOS/Umu test and Micronucleus test After the adsorption of organics with XAD 2 as adsorbent and acetone methanol as adsorbent, organics in positive samples were identified The results showed that different seasons had different leading function, and the worst is the Shang yuan men GC/MS analysis showed that positive samples had pollutants in US EPA 129 priority pollutants or other lists of priority pollutants So, this condition must be warned |
