The size-fractionated aerosol samples have been collected at Gosan Site of Jeju Island during the spring season of 2010, in order to examine the chemical composition characteristics of the Asian Dust and Non-Asian Dust particles. The concentrations of HCO₃-, Al, and nss-Ca<SUP>2+</SUP> in PM<SUB>10</SUB> had tremendously increased during the heavy Asian Dust (March 20, 2010). The concentration ratios of Asian Dust to Non-Asian Dust for the soil species (nss-Ca<SUP>2+</SUP>,HCO₃-, Al, Fe, Ti, Mn) were 12.2~30.7, meanwhile those for the anthropogenic species (nss-SO₄<SUP>2-</SUP>, NH₄+, NO₃-, K+, Zn, Pb, and Cu) were 2.9~7.8. During the heavy Asian Dust event, the concentration increase of NO₃- in PM<SUB>2.5</SUB> were much more apparent than those of nss-SO₄<SUP>2-</SUP> and NH₄+, and the soil species (nss-Ca<SUP>2+</SUP> and HCO₃-) showed much higher concentration increase. The neutralization factor of NH3 was higher than that of CaCO₃. However, the neutralization factor of CaCO₃ in PM<SUB>10</SUB> was exceptionally high during the heavy Asian Dust, showing the evidence of heavy migration of soil particles. From the study for size fractionated particles, it was found that nss-SO₄<SUP>2-</SUP> and NH₄+ were mostly distributed in fine particle mode, on the other hand, NO₃- existed evenly in both fine and coarse particle modes, and the soil species (nss-Ca<SUP>2+</SUP>, Al, Fe, etc.) were mainly in the latter mode. During the heavy Asian Dust, in particular, the concentrations of NH₄+, nss-SO₄<SUP>2-</SUP>, K+, Zn, and Pb had increased in coarse particle mode as well.
