摘要
为了解不同工业污水对环境造成的污染程度,以蚕豆根尖细胞为试验材料,利用蚕豆根尖微核技术,对重庆市4种类型工业污水对蚕豆根尖细胞的遗传毒性进行微核测定试验。结果表明:农药厂、化工厂(2个)、电池厂、油漆厂等污水诱发的微核细胞率分别为(22.33±0.88)‰、(30.67±0.88)‰、(39.67±1.76)‰、(33.33±1.76)‰、(25.00±1.16)‰,与阴性对照组相比,差异极显著(P<0.01)。结论是不同类型的工业污水对蚕豆根尖细胞微核的影响有差异,其中,化工厂和电池厂的污水诱导的蚕豆根尖细胞微核率最高,而农药厂和油漆厂污水诱导的蚕豆根尖细胞微核率较低。
The genotoxicity of 4 kinds of industrial sewages on root tip cells of vicia faba were tested by micronucleus assay to understand environmental pollution degree from the sewages. The results show that micronucleus frequencies induced by the sewages from a pesticide factory, two chemical plants, a battery factory and a paint factory are （22.33 ±0. 88）‰, （30.67±0.88）‰, （39. 674±1.76）‰, （33. 334±1.76）‰,and （25.00±1.16）‰ respectively. There are significant differences between the treated groups and the control. It shows that the micronucleus frequencies induced by several industrial sewages are different. The mieronucleus frequencies induced by the chemical industrial sewage and the battery industrial sewage are higher than that induced by the paint industrial sewage and the pesticide industrial sewage.
