Abstract The aim of the study was to assess the benzene exposure of workers in a large petrochemical plant and to determine which biological exposure index, urinary benzene, trans,trans-muconic acid (t,t-MA) or S-phenylmercapturic acid (S-PMA), showed a better correlation with the individual exposure. The environmental and biological monitoring data show that benzene exposure is low (means: benzene in air 0.022 mg/m3; urinary benzene 1.22 μg/L; t,t-MA: 81.9 μg/g creat.; S-PMA: 2.80 μg/g creat.). Significant correlations have been found between exposure to benzene and biomarkers, but with significant scattering of the data. For such low levels of benzene in the air, environmental monitoring seems to be the best method of evaluating individual exposure.
