EFFECT OF BENZENE,TOLUENE,XYLENE OCCUPATIONAL EXPOSURE ON DNA DAMAGE OF PERIPHERAL BLOOD CELLS IN FEMALE JEWEL PROCESSING WORKERS

[Objective] To study the effect of benzene,toluene,xylene occupational exposure on DNA damage in female jewel processing workers.[Methods] Measured the concentrations of benzene,toluene,xylene in working environment,and DNA damage by single cell gel-electrophoresis.[Results] The TWA of benzene was higher than national standard,the DNA damage rate of observation group(6.93%) was higher than that in control group(3.17%).[Conclusion] Exposure to benzene,toluene,xylene could induce DNA damage on female workers' peripheral blood cells.
