摘　　要：目的与方法 :本文采用Ames试验、小鼠骨髓嗜多染红细胞微核试验、鱼外周血有核红细胞微核试验 ,对基本饮用水的水源水、出厂水、末稍水、水泥水箱水、开水经XAD - 2大孔树脂吸附、丙酮洗脱的浓缩物进行致突变性研究。结果与结论 :结果发现 :各水样的浓缩物均具有致突变作用。致突变活性的大小依次为出厂水、开水、末稍水、水泥水箱水、水源水。Purpose and Methods: By Ames, micronucleus test on mouse bone marrow polychromatic erythrocytes(PCE)and fish peripheral blood erythrocyte the mutagenicity of concentrated substance with XAD-2 big hole resin is studied in the out factory water,tip water,cement chamber water,boiling water and source water.Results and Conclusion: The results showed that the concentrated substances of all samples have mutagenic effect.The mutagenic active size is in proper order out-factory water,boiling water,tip water,cement chamber water,source water.
