PMF를 이용한 구미지역의 VOCs 오염원 및 기여도 확인

Abstract

IIn this research, ambient VOCs samples were collected by specially prepared stainless steel canisters from August 2002 to September 2004 at seven representative sites in Gumi. 29 kinds of VOCs which are presented by United States EPA method TO-14 were analyzed using GC/MSD. Based on the monitored data, the characteristics of VOCs concentrations in atmosphere in Gumi were grasped, pollution sources and contributions were also analyzed by PMF model, one kind of receptor models. As a whole, the average annual concentrations of VOCs in industrial complexes were higher than that in residential areas. In residential area1 and residential area2, the VOCs that had high concentrations in industrial complexes showed comparatively lower concentrations. But the aromatic substances mainly attributed to vehicle exhaust showed high concentrations which indicated that VOCs emitting sources in industrial areas have no direct effect on the VOCs concentration in residential areas. The results from PMF modeling indicated that a total of seven sources were independently identified and each source was contributed to the ambient Gumi City from Freon relation source (17%), electronic industrial complex source (27.86%), organic solvent source (19.26%), vehicle exhaust source (17.59%), Textile relation source (8.31%), and unknown source - 1, 2 were up to 2.96%, 7.02% in terms of VOCs, respectively.
