The objective of this study was to quantitatively estimate PM2.5 source contribution in Baengnyeong Island. Based on PM2.5, ionic species (SO4 2−, NO3 −, Cl−, Na+, NH4 +, K+, Mg2+, Ca2+), organic and elemental carbon (OC, EC) and trace metal species (S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Cd, Pb), the PMF model was applied to estimate the quantitative contribution of air pollution sources. The results of the PMF modeling showed that the sources were apportioned by Coal combustion (27.0%), secondary sulfate (25.2%), sea salt + biomass burning (24.5%), secondary nitrate (12.2%), soil (7.2%), oil (3.8%), and motor vehicle (0.1%), respectively.

본 연구에서는 백령도 지역에서 PM2.5의 배출원 확인과 기여도를 파악하고자 하였다. PM2.5, 이온성분(SO4 2−, NO3 −, Cl−, Na+, NH4 +, K+, Mg2+, Ca2+), 탄소성분(OC, EC), 금속성분(S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Cd, Pb) 을 바탕으로 EPA에서 제공하는 Positive Matrix Factorization(PMF) 모델을 적용하였다. 7개의 배출원을 확인하였으며, 그 기여도는 Coal combustion이 27.0%(5.2 μg/m3), Secondary sulfate가 25.2%(4.9 μg/m3), Sea salt + Biomass burning이 24.5%(4.7 μg/m3), Secondary nitrate 12.2%(2.3 μg/m3), Soil 7.2%(1.4 μg/m3), Oil 3.8%(0.7 μg/m3), Motor vehicle 0.1% 순으로 기여도를 나타냈다.
