The purpose of this study is to investigate the current status of automatic measuring systems for air pollution emissions in Seoul and to suggest an improvement method using GIS and GPS. In Korea, there have been very few critical researches and managements for mobile and area sources regarding moving subjects such as automobiles. In order to control or to make a plan for reducing air pollutions, air pollution emission data based on tim and location, emission inventory systems and emission models should be implemented. Using digital maps and MS Visual Basic, we developed a visualized interface for air pollution emission data from automatic emission measurement systems in Seoul.

광화학스모그에 의한 오염이 심각하다고 알려진 서울의 경우 오존 1시간 환경기준 초과횟수는 '95년에 21회, '96년 174회, '98년 269회, 그리고 2000년에는 335회 등 매년 증가하고 있으며, 측정지점별 초과 횟수의 경우에도 완만한 증가추세를 보이고 있다. 2000년 말 현재 전국 53개 도시에 대기오염 자동측정 망이 약 152개소가 운영되고 있으나, 측정소의 절대적 개수를 계속하여 늘릴 수 없다는 한계와 시·공간적으로 변화하는 오존 전구물질(NOx, VOCs 등) 및 오존의 현황자료 부족으로 인하여 광화학 대기오염의 생성 규명을 파악하는데 어려움이 있다.

Using a computationalfluid dynamics(CFD) model, thisstudy evaluated the representativeness of an air quality monitoring system (AQMS) in an urban area and presented a methodology to determine the suitable AQMS locations for specific purposes. For this, we selected a 1.6 km × 1.6 km area around the Eunpyeong-gu AQMS (AQMS 111181) as a target area. We conducted simulationsfor two emission scenarios (scenario one: air pollutants transported from inflow boundaries, scenario two: air pollutants emitted from roads). Urban airflows were markedly influenced by mountainous terrain located in the northeast and southeast of the target area, and complicated airflow patterns occurred around the buildings. The distributions of air pollutants were dependent on the terrain (mountain) in scenario one, but the road location and building height in scenario 2. We evaluated whether the AQMS could represent the air quality in the target area based on the simulations for two scenarios. The concentrations simulated at the AQMS were similar in magnitude to the layer mean concentrations, which indicated good representativeness for the air quality in the target area. We also suggested which locations were suitable for different measurement purposes (hot spots, clean zones, average zones, shelter zones, equi-background zones).

울산지역은 1962년 공업 특구로 지정된 후 지난 30년 동안 우리나라의 기간 산업인 석유화학, 제련, 자동차, 조선공업 등 대단히 크고 많은 생산시설이 입주하여 운영 중에 있다. 특히 1974년부터 가동된 온산 국가공업단지에 많은 비철금속관련 업체들이 들어서면서 해양, 토양 뿐 아니라 대기중의 중금속 오염도를 가속 시켜 왔다. 최근 환경부 대기중의 중금속 측정망 분석 결과에 따르면 울산은 국내 여러 공단 도시에 비해 중금속의 오염정도가 매우 심각한 것으로 나타나고 있다. 특히, 온산공단의 대기나 토양의 카드뮴의 오염은 국내 최고치를 나타내고 있다.
