Abstract

Aerosol characterization study for individual particle in Busan metropolitan industrial complex was carried out from December 2010 to August 2011. SEM(scanning electron microscope)-EDX(energy dispersive x-ray) analysis was used for the analysis of 600 single particles during the sampling periods to identify non-metallic aerosol particle sources. Average <TEX>$PM_{10}$</TEX> concentration was 65.5 <TEX>${\mu}g/m^3$</TEX> in summer, 104.1 <TEX>${\mu}g/m^3$</TEX> in winter during the sample periods. And Average <TEX>$PM_{2.5}$</TEX> concentration was 24.5 <TEX>${\mu}g/m^3$</TEX> in summer, 64.5 <TEX>${\mu}g/m^3$</TEX> in winter individually. Particle density, enrichment factor, correlation analysis, principle component analysis were performed based on chemical composition data. Particle density distribution was measured to 2~4 <TEX>$g/cm^3$</TEX>, and the density of <TEX>$PM_{2.5}$</TEX> was measured above 3 <TEX>$g/cm^3$</TEX>. In general, the elements Si, Ca, Fe and Al concentrations were higher in all samples of individual particles. The non-ferrous elements Zn, Br, Pb, Cu concentrations were higher in summer than in winter. The concentrations were not changed with the seasons because of non-ferrous industry emission pattern.
