초록

Using the CAPSS emissions data, we analysed changes and reasons in the annual air pollutant emission trends from 1999 to 2014. The CO emissions in the metropolitan area decreased steadily since 2001, when the latest model year of automobiles and high efficiency fuel were applied. However, other regions have not changed significantly in annual emissions. NOx emissions continued to increase since 2003, and unchanged after the decline in 2007. SOx emissions are steadily declining due to the supply of low sulfur oil. The PM10 and PM2.5 emissions were repeatedly affected by the influence of motor vehicles activities in the metropolitan area. In Gangwon and Chungcheong Provinces, emissions are increasing according to the use of coal in the manufacturing sector. And VOC and NH3 emissions are increasing steadily every year.
The major CO emission sources was automobiles in the metropolitan area. However, agricultural residue burning was the biggest CO sources in the Chungchong, Honam and Yeongnam Provinces. The major sources of NOx emissions differ from region to region. In the Metropolitan area, Honam and Yeongnam region, the truck was the largest emitter of NOx. However, the cement kiln was the largest producer of NOx in Gangwon region, and the power plant is the largest emitter in Chungcheong Provinces.
