영문 초록

Objectives: In this study, the size distribution of airborne particulates (PM10) was measured by using Cascade Impactors. The purpose of this study was to assess the size distribution of metal and ionic materials of PM10. Methods: Samples were collected in the Kunsan industrial complex from April 2006 to January 2007. Results: The mass fraction of PM10 had a bimodal distribution between 2.1-3.1 μm, and the average mass fraction of particles less than 2.1-3.1 μm was 47%. Average concentrations of PM10 were 68.05 μg/m3 and seasonal concentration 95.44 μg/m3 for spring, 49.03 μg/m3 for summer, 81.99 μg/m3 for fall, 52.66 μg/m3 for winter, respectively. Conclusions: Seasonal variations of PM10 were significant for showing peak values in spring. The average concentrations of Cd, Cr, Pb, and Fe were 1.54, 4.51, 14.11, and 254.3 ng/m3, respectively. The ratios of fine particles to total mass were 0.47 for PM10, 0.45 for Cr, and 0.16 for Fe, 0.91 for Cd and 0.49 for Pb, respectively.
