Recent epidemiologic studies revealed that the concentration of air pollutants and fine particulated matter have some effects on health status and are associated with increased mortality and morbidity. ’The purpose of this study was to characterize background mass concentration of fine particle (PM2.5) and metallic composition from September 2001 to August 2002 in comparison with a medium city, Asan and metropolitan city, Seoul. Conclusively, proper management for fine particles was required in a medium city, Asan, considering the concentrations of metallic elements in fine particles in Asan were relatively higher than those in Seoul. The results were as followed.1. Average mass concentrations of fine particles in Asan and Seoul were 37.70Ct18.41 ttg/m’) and 5.83(:t38.50) ttg/m’, respectively. When the weather conditions were classified as normal and yellow-sand, measured average mass concentrations of fine particles in yellow-sand weather condition was significantly higher than those of normal weather condition in both cities (p 2. Depending on seasons, measured average mass concentrations of fine particles in Asan and Seoul in spring were 47.76(:t19.07) ttg/m’m and 61.53 (:t4.37) ttg/m’, respectively. In summer, the average mass concentrations of fine particles in Asan and Seoul were 29.44(:t9.85) ttg/ m’ and 25.42(:t8.l0) ttg/m’. respectively. Especially, the concentration was the highest in spring and the lowest in summer among four seasons. 3. Average concentrations of manganese(Mn), iron(Fe), chromium(Cr), cadmium(Cd), lead(Pb) and silicon(Si) in fine particles in Asan were significantly higher in Seoul (p4. Considering the characterization of four seasons, average Pb concentration of fine particle in Asan is significantly higher than that of Seoul in spring(p5. Mass concentrations of each 1Vln, Fe, Cd and Si in fine particles were significantly cOITelated with both cities. In nomal weather condition, 1Vln, Cu and Si concentrations are statistically significant in Asan, while 1Vln, Fe, Cu and Si concentrations are statistically significant in Seoul. Mn, Fe and Si concentrdtions in both cities were statistically significant during yellow-sand weather.
