Sources of fine-particle organic matter in Boise
Ambient concentrations of fine-particle extracted organic matter (EOM) measured at the Elm Grove Park and Fire Station sites in Boise have been apportioned to their two principal sources, wood smoke and motor-vehicle emissions. A multiple linear-regression method using lead and potassium-based tracers for motor vehicles and wood smoke, respectively, was employed in the source apportionment. On average wood smoke was found to be the dominant contributor to EOM at both sites and during both day and night. In spite of the 90% reduction in the lead content of leaded gasoline in the U.S., which has been in effect since January 1986, lead still appears to be a viable tracer of motor-vehicle emissions.
