1981 -2000 Emission Trends and the Influence by Economic Crisis in Korea

In this paper, it was developed annual emission trends of sulfur dioxides(SO2), nitrogen oxides(NOx), carbon monoxide(CO) and volatile organic compounds(VOC) during 1981 2000 period, and analyzed how a Korean economic crisis influenced an air pollution emission trends. This paper documents the methods and data sources that were used to develop the emission trends data and presents a discussion of the major factors producing these trends. It was applied emission estimation methodologies and emission factors reported recently by U.S. EPA and CORINAIR. And the emissions were calculated from major source categories, fuel combustion, on-road vehicles, non-road mobile sources, solvent utilization and waste treatment. It is calculated emission from industry, heating and electricity production by the fuel consumption. The emissions from motor vehicles included hot and cold start emission and evaporative emission were considered. Activity data of construction equipments, farming machine, air flight and railroad vehicles were accounted for the emission estimation from non-road mobile sources. And also it is calculated an emission by waste incineration and landfill treatments. Analytical limitations and future improvements are described in the conclusion section.
