紫露草微核技术检测消毒剂的致突变性

Tradescantia-Micronucleu Test for Mutation of Disinfectant

本实验通过紫露草微核技术检测7种新型消毒剂的致突变性。结果表明:紫露草四分体微核率随各种消毒剂浓度(在使用浓度内)增加而升高,但与蒸馏水(阴性对照)相比无显著差异(P>0.05),与500ppm甲醛(阳性对照)比较有非常显著差异(P<0.01)。因此7种消毒剂在使用浓度内对紫露草无遗传毒理效应,使用上是安全的。

This experiment determined mutation of several new disinfectants with Tradescantia-Micronucleu Test.The results showed Tradescantia Micronucleu Rate increased according to increasing of disinfectant concentration,but as compared with distilled water(negative control).There was no significant difference(P>0.05),and there was very significant difference(P<0.01)as compared with 500ppm of Formaldehydi(positive control).7 disinfectants have no genetic toxicity in usage concentration.
