Abstract
ent eforts since the 1960s. Consequently, the city has become one of the most seriously afected by air polution among OECD member countries. Although the Korean Government claims to be actively working to improve the air quality, as of yet there has not ben any significant, positive effects because policies typically foalready created and fail to address the original causal factors and important changes in the environment. This study is a preliminary research analyzing the correlation between air pollution and urban development density factors (ex. population, employment, land use, transportation, etc.) to determine their contributions to air Gradually the level of NO2, and PM10 in the CBD, Yeongdeungpo, and Yeongdong has become higher than in other areas and is covering a broader area than others. It was found that in these areas, which serve as centers of employment, there were higher levels of energy consumption by commercial-business activities and trahigher levels have a direct effect on air quality. Moreover, each district within these areas was found to be impacted by diferent development density factors. This study determined that wiser land use and transportation planning need to be established in consideration to changes in regional air pollution to manage air quality
