초록

Low-Z particle electron probe X-ray microanalysis (low-Z particle EPMA) was applied to characterize aerosol particles collected at Gosan in Jeju island during an IOP (intensive observation period) for an international ACE-Asia project in April, 2001. Various types of atmospheric particles such as organics, carbon-rich, aluminosilicates, silicon oxide, sodium nitrate, sodium chloride, and ammonium sulfate were observed. The reacted sea salt particles such as sodium nitrate were the most abundantly encountered, but original sea salt particles were rarely observed. Since the Low-Z particle EPMA can provide quantitative information on the chemical composition of aerosol particles, many different particle types on the basis of their chemical compositions were observed and identified. In this study, it is demonstrated that the Low-Z particle EPMA can provide detailed information on the chemical compositions for the aerosol particles collected for six consecutive days in April, 2001, at Gosan super-site.
