초록

In this study, the PM2.5 samples collected at industrial complex area in Gimcheon from June 2017 to November 2017 were analyzed. Collected samples were analyzed for determining 25 elements and 7 ionic species by inductively coupled plasma and ion chromatography. The objective of this study was to estimate the concentration trends and chemical composition characteristics of PM2.5 in industrial complex area, and these results suggest the possible role for establishment and management of efficient and reasonable atmospheric environment policies in sampling area. In the case of Gimcheon air pollution monitoring station PM2.5 data, about 27.2% exceeds the ambient air quality standard. The average concentration of the PM2.5 in summer was 15.54 μg/㎥, and average concentration of the PM2.5 in Fall was 30.74 μg/m3, respectively. In the case of Si, S, Na, Pb, Fe, K, and Ca showed high concentrations during the sampling period. Also, in the case of ionic species, SO₄2- in summer and NO₃- in fall represented the highest concentrations. To determine the location of local sources, enrichment factor analysis were performed and windrose plots were estimated using air pollution monitoring station PM2.5 data coupled with the wind direction values. The windrose plot indicated PM2.5 emission source located to the northeast, east-southeast in both low and high concentrations.
