| Popis: | Road dust is a major source for airborne particulate matter (PM). It is an agglomerate of deposited particles from vehicle exhaust, tire wear, break-lining wear, road surface and litter abrasions, local soil dust, vegetative detritus, and atmospheric fallout from many sources. Consequently, road dust is a mixture of coarse PM (road surface abrasions, soil dust, tire wear, and brake-lining wear) and fine PM (vehicular exhaust and portions of most sources of coarse PM). Although most studies concerned with road dust report the inorganic composition, only a few focus on organic constituents. Here, as part of the San Joaquin Valley Fugitive Dust Characterization Study, road dust samples from paved and unpaved urban and rural roads have been analyzed for close to 200 individual organic compounds, including n-alkanes, n-alkanoic and alkenoic acids, n-alkanols, n-alkanals, n-alkan-2-ones, alkylcyclohexanes, steroids, steranes, hopanes, triterpenoids, isoprenoids, benzothiazoles, polycyclic aromatic hydr... |
