The variation of the physicochemical properties of atmospheric aerosols in coexistence of the heavy Asian Dust and Haze observed from 15<SUP>th</SUP> to 17<SUP>th</SUP> March 2009 in Seoul was scrutinized through the mass and ion concentration observations and synoptic weather analysis. Although the ratio of PM1.0/PM10 was constant at 0.3 (which is typical during Asian Dust period in Korea) during the measurement period, both PM10 and PM1.0 mass concentrations were 3~6 times and 2~4 times higher than that of clear days, respectively. Water-soluble ion components accounted for 30~50% of PM10 and 50~70% of PM1.0 mass concentration. One of the secondary pollutants, NO₃? was found to be associated with Ca<SUP>2+</SUP> and Na? in coarse mode indicating that the aerosol derived from natural source was affected by anthropogenic pollutants. While the acidity of the aerosols increased in fine mode when the stagnation of weather patterns was the strongest (March 16<SUP>th</SUP>), the alkalinity increased in coarse mode when new air masses arrived with a southwestern wind after ending a period of stagnation (March 17<SUP>th</SUP>). In the selected case, SOR (Sulfur Oxidation Ratio, nSO₄<SUP>2-</SUP>/[nSO₄<SUP>2-</SUP>+nSO₂]) and NOR (Nitrogen Oxidation Ratio, nNO₃?/[nNO₃?+nNO₂]) values of ion components were higher than the general values during Asian Dust period. These results imply that dust aerosols could be mixed with pollutants transported from China even in heavy Asian Dust cases in Korea.
