Abstract
In this study, analysis was conducted using the PMF acceptance model to identify the emission source and contribution of fine particle (PM2.5). The measurement point was selected as the Daejeon area, where industrial complex areas, residential areas, and rural areas are located nearby, and thus can be affected by multiple factors. Measurement data were collected and analyzed during the winter (January) and summer (May, June) periods. As a result of the analysis of the PMF model, it was classified into 7 factors, namely, dust, sea salt particles, secondary nitrate and chloride, secondary sulfate, industrial emissions, coal combustion, and vehicle emissions. As a result of checking the contribution by season, the contribution of dust and sea salt particles was high during that period due to the yellow dust event that occurred in May-June. In the case of secondary products, nitrate and hydrochloride were higher in winter than in summer due to the phase change at room temperature, and in the case of coal combustion, they were higher in winter. Through this, it was judged that the PMF result was good.
