Abstract

The purpose of this study was to investigate the scientific basic grounds for the assessment of health and environmental diseases resulting from air pollutants in Pohang. For this study, we investigated pollutants, weather characteristics and concentration distribution of fine particles ($PM_10$) yearly and each season, using data from Air Quality Monitoring Stations. The properties of concentration distribution and seasonal fluctuation of $PM_10$ were studied qualitatively and quantitatively using CALPUFF, air dispersion model. The average concentration of $PM_10$ for each season was spring($75.7{\mu}g/m^3$)>summer($56.8{\mu}g/m^3$)>winter($53.6{\mu}g/m^3$)>fall( $52.7{\mu}g/m^3$). In the case of spring, high concentrations appear due to the Asian dust frequently occurring. The contributions of $PM_10$ classified by the types of pollution source in Pohang were point source 62%>mobile source 33%>area source 5%. An important point is that 97% of emissions were produced from the iron manufacture in steel industry. Therefore, it is necessary to control the emission sources of pollutants and to construct an observation system at Pohang steel industrial complex from now on. It’s time to control the risk factors for health and environmental disease to protect the health of resident in Pohang and its neighboring areas.

본 연구는 포항지역 환경오염물질의 보건 환경 위해성 평가를 위한 기초연구의 일환이며, 이를 위하여 포항시에 소재한 지역대기자동측정 자료를 이용하여 연별, 계절별 $PM_10$ 농도분포에 대한 현황, 기상특성 및 오염물질 농도분포 분석을 수행하였고, 대기확산 모델(CALPUFF)을 이용하여 농도분포 특성에 대해 정성적, 정량적으로 확인하였다. 포항지역의 $PM_10$ 농도분포를 확인한 결과, 포항지역의 계절별 $PM_10$ 평균농도는 봄($75.7{\mu}g/m^3$)>여름($56.8{\mu}g/m^3$)>겨울($53.6{\mu}g/m^3$) >가을($52.7{\mu}g/m^3$) 순으로 봄에는 빈번히 발생하는 황사의 영향으로 높은 농도를 나타내었다. 포항지역 오염원별 $PM_10$ 배출량은 점오염원 62%>이동오염원 33%>면오염원 5% 순이며, 점오염원 중 전체 97%가 철강산업인 제철제강업에서 발생되었다. 포항지역은 $PM_10$의 영향을 많이 받고 있는 지역으로 포항철강공단지역에 대한 환경오염물질 원인배출원에 대한 감시체계의 보완 및 집중관리와 함께 포항지역 주민의 건강 보호를 위하여 보건 및 환경에 악영향을 미치는 위해인자 및 오염물질을 원천적으로 차단하는 작업이 지속적으로 수행되어야 할 시점이다.
