| Abstract: | Hydroxybenzene compounds are environmental endocrine disrupting chemicals,and the "comet"assay,which is known as a test for genotoxicity,appears to be a promising tool to estimate DNA damage at the single cell level.In this paper,the toxicity of eight hydroxybenzene compounds on different biomaterials was detected by the comet assay.The results indicated that all the tested substances could induce DNA damages at different levels,and in a certain range,the dose response relations were obvious.There was significant difference ( P <0 01)between high dose group and control.The results also showed that the damages of different biomaterials induced by the same substance tested were different.The genotoxicity of hydroxybenzene compounds was partly reated to the structures of them. |
