Abstract
In order to analyze the effect of each component such as fine particles, ion, carbon, and metals on the air quality of Gwangju area due to long-range transport, the change of concentration characteristics was hourly measured in Gwangju Metropolitan City from March to May and air flow cluster analysis using backward trajectory was performed on high PM episodes. Regression analysis between OC and EC concentration showed that OC and EC were emitted by different pollutants. The ratio of OC / EC was
미세먼지, 이온, 탄소성분 및 중금속 등 각 성분들이 장거리 이동에 따라 광주지역 대기질에 미치는 영향을 분석하고자 2016년 3월부터 5월까지 봄철 기간 동안 광주광역시에 위치한 호남권대기오염집중측정소에서 1시간 간격으로 측정하여 농도특성 변화를 파악하였고, 고농도 이벤트 사례에 대해 기류분석 등을 수행하였다. OC와 EC 농도 사이의 회귀분석 결과, OC와 EC는 서로 다른 오염원에 의해 배출되었음을 알 수 있었으며, OC/EC의 비가
