Abstract |
Recently, the determination of S-phenylmercapturic acid (S-PMA) in urine has been proposed as a suitable biomarker for the monitoring of low-level exposures to benzene. In the study reported here, the test was validated in 12 separate studies in chemical manufacturing plants, oil refineries and natural gas production plants. A strong correlation was found between eight hour exposure to airborne benzene of 1mg/m3 (0.3ppm) and higher and urinary S-PMA concentrations in end-of-shift samples. A strong correlation was also found between urinary phenol and S-PMA concentrations. In conclusion, with the current sensitivity of the test, eight hour time-weighted-average benzene exposures of 1mg/m3 (0.3ppm) and higher can be measured. |
