Abstract

Scientific analyses were carried out to determine the effect of long-range transport of particulate matters based on chemical speciation of fine particulate matters (PM_2.5) collected from the central area of Seoul, Republic of Korea. Based on chemical analysis of PM_2.5, sources of emission of PM_2.5 were determined by employing the sequence source apportionment methods such as chemical mass balance and positive matrix factorization. In addition, the path of migration of PM_2.5 was traced employing models of residence time weighted concentration, and European Centre for Medium-Range Weather Forecasts for the period of emission increase of PM_2.5. Source apportionment results revealed that (1) biomass burning can be originated from wildfire in Russia based on fire spot monitored with a Moderate Resolution Imaging Spectroradiometer from Terra & Aqua satellites. (2) Long-range transported PM_2.5 contained secondary products of sulfate and nitrate from East of China. Data of the present study could be exploited for further studies delving into the long-range transport of particulate matters in the air.
