Size-resolved motor vehicle particulate matter emissions were characterized for light-duty gasoline-powered vehicles and heavy-duty diesel vehicles, and near a busy freeway. These profiles of carbonaceous, water-soluble ion, and elemental components were compared between chassis dynamometer studies and the freeway environment; their elemental composition was also compared to data obtained from trace metal analyses of fuel and motor oil sampled from test vehicles. The majority of motor vehicle particulate matter was carbonaceous and its size and composition distributions were impacted by emissions reduction technology, maintenance history, and driving cycle/conditions. Elements measured in stock fuel and motor oil samples, such as motor oil additives, were also measured in the motor vehicle particulate matter emissions and in the roadside environment. These analyses are important because motor vehicle PM emissions can play an integral role in affecting human health as well as negatively impact the natural environment. Cumulatively, these results present a life-cycle analysis perspective of motor vehicle particulate matter formation, emission, and exposure potential. This information provides scientists and regulators with a starting point from which they can determine how to best protect the public from particulate air pollution.categoryaquot; year make model mileage engine information fuel delivery technology15 - - v - LEV PC 1996 Honda Civic 77, 703 4 cylinder ... 8 cylinder / 302 SFI LEV LDT/SUV 2000 Jeep Grand 31, 751 6 cylinder SFI LEV LDT/SUV 2000 Toyota Tacoma 51 , 554 6 cylinder SFI ...
