Exposure to evaporative gasoline emissions that occur in selected microenvironments or during specific activities can contribute significantly to the daily volatile organic compounds (VOCs) exposures an individual receives. Three microenvironments/activities that are influenced by evaporative gasoline emissions are residential garages, public parking garages and activities surrounding refueling of an automobile. In addition, exhaust emissions contribute to public parking garage air concentrations. The emissions that occur within a residential garage can also penetrate into the attached home. This penetration has been observed within samples collected as part of the TEAM study. Gasoline emissions are one of the major sources of general population VOC exposures, acute higher environmental exposures and as VOC sources into the home indoor microenvironmental. The data presented are preliminary results from a study designed to measure the potential VOC exposures in the above mentioned microenvironments and obtain a data base suitable for evaluating mathematical models describing human exposures from mobile sources. Measurements of the benzene and toluene air concentrations were made within each microenvironments/activity using integrated adsorbent trap samples (trilayer adsorbent of Tenax GC, Carboxen 569 and Carbosieve SIII) analyzed by thermal desorption (PE-ATD400) coupled with GC/MS (HP 5890-MSD) and/or with a portable gas chromatograph (MSI-301).
