HAZARDOUS AIR POLLUTION FROM MOBILE SOURCES: A COMPARISON OF ALTERNATIVE FUEL AND REFORMULATED GASOLINE VEHICLES
Even though there have been several studies examining emissions of criteria pollutants from in-use alternative fuel vehicles (AFVs), little is known about emissions of hazardous air pollutants (HAPs) from these vehicles. This paper examines HAP exhaust pipe emissions from a variety of AFVs operating in the U.S. government fleet and compares these emissions to emissions from identical vehicles operating on reformulated gasoline. Emissions estimates are presented for a variety of fuel/model combinations and on 4 HAPs. Results indicate that all AFVs tested offer reduced emissions of HAPs, with some exceptions: ethanol fueled vehicles emit more acetaldehyde than RFG vehicles, and ethanol- and methanol-fueled vehicles emit more formaldehyde than RFG vehicles. These results can lead to more accurate emissions factors for HAPs, thus improving HAP inventory and associated risk estimates for both AFVs and conventional vehicles.
