Abstract Number: 319 Working Group: Carbonaceous Aerosols in the Atmosphere
Abstract Seoul, Korea is one of the megacities in Northeast Asia with 10 million inhabitants and 2.5 million vehicles, thus, the large emission of air pollutants from Seoul might be expected. In addition, South Korea is surrounded by China and Japan and might be influenced by transport of air pollutants from these areas in addition to local sources. Organic compounds are a large fraction of atmospheric aerosol and have significant impact on the air quality, climate change and human health. Thus, understanding the characteristics of the organic compounds in atmospheric aerosols and the contribution of the various emission sources to the organic compounds in Seoul is essential in order to assess their impact on climate change and/or health risk in Northeast Asia. In this study, PM10 samples were collected for 24 h at every sixth day with no rain from April 2010 to April 2011 at Seoul, Korea and solvent extrable organic compounds such as PAHs, n-Alkanes, n-Alkanoic acids, Dicarboxylic acids and Sugars were identified and quantified In addition, major emission sources and formation route for the organic compounds were discussed.
