The PM<SUB>2.1</SUB> was collected by LVCI (low volume cascade impactor) during Group-A Period (September 1990 to December 2012) and the PM<SUB>2.5</SUB> was collected by HVAS (high volume air sampler) during Group-B Period (September 2009 to April 2012) at Kyung Hee University, Global Campus located on the boarder of Yongin and Suwon. The 8 water-soluble ions (Na+, NH₄+, K+, Mg<SUP>2+</SUP>, Ca<SUP>2+</SUP>, Cl-, NO₃-, and SO₄<SUP>2-</SUP>) were analyzed by IC, and the 14 inorganic elements (Al, Mn, Si, Fe, Cu, Pb, Cr, Ni, V, Cd, Ba, Zn, Ti, Ag) were analyzed by XRF and ICP-AES after performing proper pre-treatments of each sample filter. The average total mass fractions of SO₄<SUP>2-</SUP>, NO₃-, and NH₄+ to PM<SUB>2.5</SUB> samples during Group-B Period were 0.39 in normal days, 0.44 in haze days, and 0.27 in Asian dust days, respectively; however, the average total mass fractions of Al, Fe, and Si to PM<SUB>2.5</SUB> mass were 0.043 in normal days, 0.021 in haze days, and 0.036 in Asian dust days, respectively. Especially the concentration of Pb was significantly decreased during Group-B Period rather than during Group-A Period, while Cr and Ni was increased during Group-B Period.
In this study, we intensively compared the annual and seasonal patterns of major chemical species among normal days, haze days, and Asian dust days. Further we developed mass fraction profiles by collecting episode cases of haze days and Asian dust days, which were consisting of 22 chemical species. Those profiles are considered to be useful when applying various receptor models and establishing air quality management plans near future.
