speciated PM2.5 air-measurement data sets collected during the summers of 2003 and during the winters of 2004 in two site: Jeonnongdong in Seoul & Yonghyundong in Incheon. Sources modeled were soil dust, road dust, gasoline vehicle emissions, diesel vehicle emissions, point, municipal incinerator, coal-fired power, biomass burning and marine emissions. As a result, vehicle emissions were the larg
