Source apportionment studies for [PM.sub.10] (PM [less than or equal to] 10 [micro]m in aerodynamic diameter) and [PM.sub.2.5] (PM [less than or equal to] 2.5 [micro]m in aerodynamic diameter) indicate that mobile sources can be responsible for over half of the ambient PM measured in an urban area. Recent source apportionment studies attempted to differentiate between contributions from gasoline and diesel motor vehicle combustion. Several source apportionment studies conducted in the United States suggested that gasoline combustion from mobile sources contributed more to ambient PM than diesel combustion. However, existing emission inventories for the United States indicated that...
