The damaging effect of subchronic SO2 inhalation on DNA in lung cells of rats was studied using single cell microgel electrophoresis technique (Comet assay). The result showed that the comet tail lengths increased significantly in lung cells of rats when the animals were treated with SO 2 of 28 mg/m3 (P < 0.01). The results also indicated that DNA in lung cells of male rats was more seriously damaged than that of female rats. In addition, compared with the control, the body weight of the rats decreased, and the weight ratio of lung to body increased. It is concluded that SO2 pollution has a potential damaging effect on genetic material DNA in lung cells of mammalian animals.
