영문 초록

The variation of the particle size distribution and density as well as the chemical composition of aerosols is important to evaluate the particles. This study measured and analyzed airborne particles using a scanning mobility particle sizer(SMPS) system and an aerodynamic particle sizer(APS) at University of Seoul during every season. Particle number concentration of airborne particles less than 0.9㎛, winter was the highest. Particle number concentration of airborne particles more than 0.9㎛, spring was the highest. Mass concentration appeared highest at spring. Also, when we compared β-ray s mass concentration with calculated mass concentration by using SMPS-APS system during each season, density of the winter is 1.92g/cm³, spring density is 1.64g/cm³, fall density is 1.57g/cm³. We found out that PM10 density was differ every season. However, calculated density is whole density for PM10, density of each diameter was differ, so this study output that density estimation equation by QCM cascade impactor to measured mass concentration of each diameter.
