| 摘 要： | 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，研究了香港某地饮用水中非挥发性有机物（NOcs）的致突变性．结果表明，在加与不加代谢活化系统（±S9）条件下，1～2 L水中的非挥发性有机物即可诱发鼠伤寒沙门氏菌（TA98）的回复突变；此外，活性炭可部分吸附水中具致突变作用的有机物

| Abstract: | In this study, drinking water samples were collected at certain area of Hong Kong. The nonvolatile organic compounds(NOC_s) in water were concentrated on resin and examined by using the Salmonella mutagenicity test(Ames test). The mutagenicity of such concentrates recovered from 1 to 2 liter drinking water could be detected by means of S.typhimurium TA98 with and without S9 m. In addition,the filtration of activated carbon could remove a part of NOCs from drinking water and therefore decrease the mutagenicity. |
