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 PM 10 concentration was 65.5 ㎍/㎥ in summer, 104.1 ㎍/㎥ in winter during the sample periods. And Average PM 2.5 concentration was 24.5 ㎍/㎥ in summer, 64.5 ㎍/㎥ 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 g/㎤, and the density of PM 2.5 was measured above 3 g/ ㎤ . 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.
