춘천시 대기 중 PM2.5 및 금속성분의 장기간 농도 특성 = Long-term Characteristics of PM2.5 and Its Metallic Components in Chuncheon, Korea

다국어 초록 (Multilingual Abstract)

In this study, PM2.5 samples were collected during approximately 3 years in Chuncheon, a small residential and tourist city, in Korea. The average PM2.5 concentration was 26.9 μg/m3, exceeding the annual national air quality standard. PM2.5 showed typical seasonal variation, having higher concentration in winter and lower concentration in summer. Sixteen metallic elements in PM2.5 were also analyzed, and K was the highest contributor especially in late fall and winter. In addition, K considerably increased for the top 10% of PM2.5 samples and showed the highest correlation coefficient with PM2.5 among all other metallic elements. These results suggest that the combustion of agricultural residue and other biomass, the major source of K was likely to be important to high PM2.5 concentration events in this city. Crustal elements including Al, Fe, Si, Ti, Mg showed high concentration in spring while Cr, Cu and Ni were relatively consistent throughout a year. Principal component analysis was used to trace the sources, and soil re-suspension, combustion of biomass and fossil fuels, and asphalt concrete production were identified as the main sources of PM2.5.
