RESUMO
Objective To study the genotoxicity of 3 kinds of different brands shampoo to Vicia faba root tip cells. Methods To take root tip cells of Vicia faba as the subjects,genetic safety tests were conducted on those materials treated with shampoo of a certain concentration(0.25% ) for 2-8 h of continual mutagenesis and accumulative mutagenesis respectively,micronucleus and chromosomal aberration was observed and calculated,the rate of tap water was used as the control. Results Three kinds of shampoo could induce root tip cells of Vicia faba to produce micronucleus and chromosomal aberration,the peak was in the continual mutagenesis for 4 h and accumulative mutagenesis for 8 h respectively,which showed dose-effect relationship. There were significant differences between the control group and the experimental groups( P
