چکیده انگلیسی
Biomarkers of benzene exposure and effect were evaluated in 158 Bulgarian petrochemical workers and 50 matched controls. Air exposures to benzene averaged about 1.8Â ppm, for workers and 0.02Â ppm for controls. Urinary trans,trans-muconic acid, and S-phenylmuconic acid, showed dose response relationships with benzene air exposure. The dose response curve for DNA single strand breaks (SSB), but not for the metabolites, showed a saturation effect. NQO1 genotype had a significant effect on SSB. We conclude that the pathways for these metabolites may be distinct from those involved in some forms of genotoxic damage induced by benzene.
