| ABSTRACT |
|
In order to improve air quality in the Seoul Metropolitan Area (SMA), the “Special Act on Seoul Metropolitan Air Quality Improvement” has been enforced since 2005. The strategy has resulted in some reduction of air pollution, but there has not been much research into the quantitative impact analysis of each separate preventive countermeasure. Therefore, we analyzed nitrogen oxide reduction resulting from implementation of the emission control plan for on-road mobile sources. The MM5-SMOKE-CMAQ model system was employed for air quality prediction. Reduced NOx emissions for SMA was 16,561 ton, 4.7% of reduction rate, in 2007. One countermeasure, tighter acceptable standards for manufacturing vehicles, dominated other counter-measures for effective NOx emission control. Large spatial differences in reduced emissions, those for Seoul being twice that of Incheon and Gyeonggi, showed greater NOx emission reduction impact in the heart of the metropolitan complex. The NO2 concentration decreased by 0.60 ppb (2.0%), 0.18 ppb (1.5%), and 0.22 ppb (1.7%) in Seoul, Incheon, and Gyeonggi, respectively. Concentration decreases in spring and winter were larger, 1.5~2.0 times, than summer and fall. However, the NO2 reduction impact did not correspond directly to local NOx emission controls in the city area because of the natural flow and dispersion, both urban and downwind. |
