【摘要】 本研究对南宁市某自来水厂水源水及自来水用XAD-2型树脂浓集水中有机物,进行Ames试验(选用TA₉₈和TA₁₀₀菌株加与不加S₉),观察其致突变活性作用。结果表明,水源水和自来水有机物均引起TA₉₈和TA₁₀₀菌株致突变作用阳性,且有剂量与反应关系,其回变菌落数随剂量递增而增加。更多还原

【Abstract】 The mutagenic activity of organic pollutants in the source water and tap water of Nanning municipal water works was studied with Ames test using TA98 and TA100 strains with or without S₉.Organic pollutants were concentrated on XAD-2 esi.The results were positive for both source water and tap water to TA98 and TA100 strains in Ames test,showing also dose- response effect.There exists a range in which the number of induced revert- ants increases with the dose.更多还原
