Abstract

Objectives-To evaluate the contribution of traffic fumes to exposure to benzene in urban workers, an investigation on personal exposure to benzene intraffic police from the city of Rome was carried out. Methods-The study was performed from December 1998 to June 1999. DiffusiveRadiello personal samplers were used to measure external exposures to benzene and alkyl benzenes during the workshift in 139 policemen who controlledmedium to high traffic areas and in 63 office police. Moreover, as biomarkers of internal exposure to benzene, blood benzene, and urinary trans, trans-muconic and S-phenyl mercapturic acids were measured at the beginning andat the end of the workshift in 124 traffic police and 58 office police. Results-Time weighted average (TWA) exposure to benzene was consistently higher among traffic police than among indoor workers (geometric mean 6.8 and 3.5 mug/m(3), respectively). Among the traffic police, the distribution of individual exposures was highly asymmetric, skewed toward higher values. Mean ambient benzene concentrations measured by municipal air monitoring stations during workshifts of traffic police were generally higher (geometricmean 12.6 mug/m(3)) and did not correlat with personal exposure values. Inparticular, no association was found between highest personal exposure scores and environmental benzene concentrations. Among the exposure biomarkersinvestigated, only blood benzene correlated slightly with on-shift exposure to benzene, but significant increases in both urinary trans, trans-muconic and S-phenylmercapturic acids were found in active smokers compared with non-smokers, irrespective of their job. Conclusion-The exposure to traffic fumes during working activities in medium to high traffic areas in Rome may give a relatively greater contributionto personal exposure to benzene than indoor sources present in confined environments. Smoking significantly contributed to internal exposure to benzene in both indoor and outdoor workers.
