Abstract

|
The total suspended particles (TSP) collected at the 1100 site of Mt. Halla have shown higher compositions for the anthropogenic components followed by marine and soil originated ones. The concentrations of the soil originated nss-Ca²?, Al, Fe, Ca components have been increased in spring, and the anthropogenic NH₄?, K?, nss-SO₄²? components showed high concentrations in June. Meanwhile, the concentration of NO₃? as same as nss-Ca²? was higher in spring. It’s likely due to the influence of its long-range transport from China. Compared to the non-Asian Dust periods, the concentrations of nss-Ca²?, Al, Ca, and Fe have been increased 7.2~9.5 times in Asian Dust storm periods, and those of nss-SO₄²? and NO₃? were 1.3 and 3.8 times, respectively. From the factor analysis, the TSP compositions were influenced mainly by anthropogenic emission sources, followed by oceanic and soil sources. The backward trajectory analysis has shown that the concentrations of the anthropogenic and soil components were increased when the air parcels had been moved into Jeju island via China in a northwesterly wind.
