This study analyzes the chemical composition of metallic elements and water-soluble ions in and . and concentrations in Busan during 2010-2012 were and , respectively, and the mean concentration ratio was 0.73. The contribution rate of water-soluble ions to ranged from 29.0% to 58.6%(a mean of 38.6%) and that to ranged from 33.9% to 58.4%(a mean of 43.1%). The contribution rate of sea salt to was 13.9% for 2011 and 9.7% for 2012, while that to was 17.4% for 2011 and 10.1% for 2012. concentration during Asian dust events was and during non-Asian dust events, and the concentration ratio of Asian Dust/Non Asian dust was 2.95. On the other hand, the concentration in Asian dust was and in Non Asian dust, and the concentration ratio of Asian Dust/Non Asian dust was 1.89, which was lower than that of .
