서울지역 대기 중 다환방향족탄화수소의 발생원별 기여도 평가 = Contributive Estimation of Polycyclic Aromatic Hydrocarbonsby Emission Source in Seoul Area

다국어 초록 (Multilingual Abstract)

PAHs(Polycyclic Aromatic Hydrocarbons), one of the carcinogenic materials in environment, were investigatedPAHs concentration in Seoul were estimated. Moreover, the emissions of PAHs from major stationary sourceswere investigated to determine the quantitative relationships between ambient PAHs concentrations and emissionsources. From the factor analysis, three factors relevant to the ambient PAHs in Seoul were found. Factor 1 was related tothe concentrations of chrysene, pyrene, indeno(1,2,3-cd)pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, andbenzo prerylene which were mainly emitted from gasoline and diesel fueled cars. Factor 2 showed higher loadingsin phenanthrene and anthracene which were due to LNG and BC oil combustion in industry and home. And factor3 included dibenz(a, h)anthracene and acenaphthene which were emitted from open burning and municipal solidwaste incineration.ambient air in Seoul was estimated at 64%, that of industrial and home sources at 17%, and that of open burningand municipal incineration at 1%.
