Abstract The work aimed to study the potential correlation between high-level benzene exposures and urinary benzene metabolites S-phenylmercapturic acid (SPMA) and trans, trans-muconic acid (t,t-MA) among Chinese shoe industry workers. Individual benzene-exposed levels were determined by gas chromatography analysis; urinary metabolites were determined by high performance liquid chromatography coupled with mass spectrometry. The concentration of benzene ranged from 2.57 to 146.11 mg/m3. The correlation between benzene and t,t-MA was significantly higher than that of SPMA at the postshift. It is concluded that t,t-MA is a more specific biomarker than SPMA at high-level benzene exposures.
