세종특별자치시의 대기질 개선을 위한 정책 방향

Abstract

This study tried to evaluate air quality in Sejong City, a new administrative capital of the Republic of Korea and discussed and recommended for the local policy measure to mitigate air pollution of Sejong in the aspect of sustainable development. Based on the accessible observations near Sejong City, PM10 and PM2.5 concentration in Sejong City is a similar level of Seoul Metropolitan Area (SMA). Ozone concentration is higher than SMA because the O3 concentration can be reduced by O3 titration due to very high surface NOx emissions. Also, the PM and VOCs emissions are relatively higher considering its population since the large construction in the city has been continued. Therefore, the strong and effective policy measure and its implementation is necessary to control the local emissions of particular matter(PM) and VOCs emissions from the transportation in the city construction field. Furthermore, the comprehensive measure, such as including managing a super site to observe diverse air pollutants and mid-and long-term planning for introducing cleaner energy and the cleaner vehicle would be considered for mitigating air pollution. Finally, the environmental impact assessment and high-level regionally cooperative air pollutants emission control could be prepared in near future considering the impact of the large emissions sources in Chung-Nam region.
