Abstract: Human epithelial lung cells (A549) were exposed to toluene and benzene in the air as individual compounds and mixtures at concentrations of about 0.25 ppmv in a specifically adapted fumigation device. Possible early toxicological effects at cellular level have been determined by LDH, GSH and comet assay. One hour of exposure to 0.25 ppmv of toluene in the air induced DNA damages which were repaired within 24 hours after the treatment. No DNA damage was detected by applying a similar concentration of benzene, but there was a decrease in the glutathione ratio. Exposure to a mixture of toluene and benzene in air lead to an increase of the cytotoxic effect and DNA damage without any further repair, but did not induce any changes in the gluthatione redox status.
