Due to the rapid economic development for the past three decades, Seoul, the capital city of the Republic of Korea with a population of 1.2 million, experienced serious air pollution problems. After practicing various pollution reduction measures such as the supply of low-sulfur oil and LNG and cut down of coals, the sulfur dioxide level improved remarkably: the annual average level of sulfur dioxide dropped from 0.066 ppm in 1984 to 0.023 ppm in 1993, a 64.8% reduction. However, due to the increase of automobiles, the nitrogen oxides and the photochemical smog are becoming the most serious air pollution problems. The annual average oxidants` level rose from 0.008 ppm in 1984 to 0.13 ppm in 1993, a 62.5% increase. The spacio-temporal analyses of the air quality using the monitoring data for the last ten years clearly revealed that the air quality changed with the urban development and countermeasure policies adopted. Future policy recommendations are made based on the analyses.
