ABSTRACT |
Particulate matter (PM) has emitted in many regions of the world and is causing many health-related problems. Thus reasonable politics and solutions are needed to reduce PM in Seoul. Further it is required to clearly explain the major portions of chemical components contained in PM10 to figure out the characteristics of PM10, and to develop effective reduction measures in order to decrease the adverse effects of PM10. PM10 samples were collected in Seoul and analyzed their ions to examine the physical and chemical characteristics of ionic species. Since hydrogen ion (H+) and carbonate ion (CO32-) cannot be analyzed by Ion chromatography (IC), concentrations of H+ and CO32- were initially estimated by pH and equivalent differences between anions and cations in this study. Starting from the study findings, good combination results for compositional patterns between anions and cations were obtained by applying a mathematical modelling technique that was based on the mass balance principle. The ions in PM10 were combined with H+, CO32-, and supplement for NO3-, Cl- formed such compounds NH4Cl, NH4NO3, CaSO4, (NH4)2SO4, NaNO3, NaCl, Na2CO3, and (NH4)2CO3 in the study area. |
