“…From the investigation that the organic acids (HCOO -, CH 3 COO -) had contributed as only 5% to the acidification of the atmospheric aerosols, it was confirmed that the acidification might be contributed mainly by the inorganic sulfuric and nitric acids (Hong et al, 2011).…”

The collection of TSP and PM 2.5 aerosols has been made at the Gosan Site of Jeju Island during 2008-2011, and their ionic and elemental species were analyzed, in order to examine the seasonal variation and characteristics of aerosol compositions. The anthropogenic components (NH 4 + + , nss-SO 4 2-, NO 3-, S, Zn, Pb) and the soil components (nss-Ca 2+ + , Al, Fe, Ca) showed high concentrations in spring as the prevailing westerly wind, but the concentrations of the sea-salt components (Na + + , Cl-) were high in winter. In TSP, the neutralization by NH 3 increased in summer, but the neutralization by CaCO 3 increased in spring and fall seasons. The organic acids (HCOO-, CH 3 COO-) contributed to the acidification of the aerosols by only 5.0%, so the acidification could be mostly contributed by the inorganic acids (SO 4 2-, NO 3-). From the examination of the source origins by factor analysis, the compositions of TSP were influenced by the order of soil¤anthropogenic¤marine, on the other hand, those of PM 2.5 were by the order of an-thropogenic¤marine¤soil. The backward trajectory analyses showed that the concentrations of NH 4 + + , nss-SO 4 2-, NO 3 and nss-Ca 2+ + increased highly when the air masses had moved from China continent into Gosan area of Jeju Island.

The collection of rainwater samples was made at Jeju area during 2009~2010, and the major ionic species were analyzed. In the comparison of ion balance, conductivity, and acid fraction for the validation of analytical data, the correlation coefficients showed a good linear relationship within the range of 0.966~0.990. The volume-weighted mean pH and electric conductivity were 4.9 and 17.8 μS/cm, respectively, at the Jeju area. The volume-weighted mean concentrations of ionic species in rainwater were in the order of ClThe ionic strength of rainwater was 0.26±0.21 mM during the study period. The composition ratios of ionic species were such as 50.1% for the marine sources (Na , and nss-SO 4 2-increased in winter and spring seasons, indicating a reasonable possibility of long range transport from Asia continent. Especially, the acidifying contributions by major inorganic acids (nss-SO 4 2-and NO 3 -) and organic acids (HCOO -and CH 3 COO -) were 87.6% and 12.4%, respectively. In comparison by sectional inflow pathway of air mass during the rainy sampling days, the concentrations of nss-SO 4 2-and NO 3 -were relatively high when the air mass was moved from the China continent into Jeju area.
