The Objective of this study is to examine the characteristic of fine aerosol (PM<SUB>2.5</SUB>) obtained at Ieodo Ocean Research Station, which lies between the eastern part of China and the south western part of Korea. The average mass concentration of PM2.5 was 21.5±17.0 ㎍/㎥ during June 2004~June 2006. The concentration was the highest in winter (34.8 ㎍/㎥) and lowest in summer (16.5 ㎍/㎥). Water soluble ions were measured for samples collected from December 2004 to September 2005. Among them, SO₄²? and NH₄? were the most abundant species and accounted for 32.2% and 14.2% of the PM<SUB>2.5</SUB> mass, respectively. The mass fraction of SO₄²? was higher in winter (42%) than in spring (26%). Nitrate concentrations were much lower than those of sulfate due mainly to evaporation during sampling period. The cluster analysis of backward airmass trajectories showed that the high mass loadings (26.9 ㎍/㎥ on average) were associated with air originating inland China. Also, the seasonal variation of PM<SUB>2.5</SUB> mass was well correlated with the frequency of westerly winds passing through the western part of China. During the ABC-EAREX2005 (March 2005), PM<SUB>2.5</SUB> mass and major ionic concentrations were higher at Ieodo, compared with PM<SUB>2.5</SUB> measurements at Gosan while they were similar in variation pattern. These results suggested that PM<SUB>2.5</SUB> mass and its ionic composition of Ieodo Ocean Research Station were greatly influenced by continental outflows from China.
