Information on potential genetic damage in humans after exposure to waste anaesthetic gases is scarce. Also the circumstances in many hospitals are somewhat inadequate. To evaluate the possible genotoxic effects of waste anaesthetic gases on staff was our main aim. The chromosomal aberrations CA] analysis and the sister chromatid exchange SCE] test were studied in peripheral blood lymphocytes. The results showed a statistically significant increase in chromosomal aberrations and sister chromatid exchange. The results of our study signify that exposure to anaesthetic gases induced changes in...
