Study on Genetic Toxicity of Detergent to Root Tip Cells of Vicia faba / 环境与健康杂志

ABSTRACT

Objective To study the genetic toxicity of 3 brands of detergents to the root tip cells of Vicia faba in the inducing time and the inducing way(continual mutagenesis,accumulative mutagenesis) with micronucleus and the chromosomal aberration Methods The root tip cells of Vicia faba were taken as the subjects,the genetic safety tests were conducted on those materials treated with detergent of a certain concentration(0.25%) for 2、4、6 h of continual mutagenesis and accumulative mutagenesis respectively.Distilled water was used as the control.Results The continual mutagenesis showed that all the three detergents could induce the root tip cells of Vicia faba to produce micronucleus and chromosomal aberration and as the mutagenic time prolonged,at 6 h,the changes became weak.The genetic toxicity in the accumulative mutagenesis group was greater than that in the continual mutagenesis group.Conclusion According to the results of the present paper,to some extent,detergents may produce genetic toxicity.
