Abstract:

"Using analyzed and modeled field data on air quality and meteorology, researchers identified major contributors of fine particulate matter (PM2.5) in Fairbanks. This ; project was an effort to help the city meet U.S. Environmental Protection Agency air quality standards, which require reduced levels of PM2.5, a pollutant. Findings ; showed that during December and January, traffic is a significant contributor to PM2.5 at the bus barn on Peger Road, and motor vehicles are responsible for about 30% ; of PM2.5 downtown. Data on soot (black carbon) indicated that wood smoke is a significant contributor to PM2.5 during the heating season. A chemical mass balance ; model revealed that road dust, biomass burning (wood smoke), and motor vehicles are significant contributors to PM2.5 at the bus barn. With respect to Transportation ; System Management Strategies, working at home has the biggest potential to improve ambient air quality, but even if 5% of commuters worked from home, the PM2.5 ; downtown would be reduced by only about 0.4%. The research team concluded that Fairbanks will have to adopt major changes in its TSM strategies to effect significant ; reductions in downtown PM2.5 levels."
