Investigation of air emissions’ characteristics in the southeast part of Korea to create modeling emission inventories for PM2.5 predictions

Reliable results for the fine particulate matter (PM2.5) predictions are very useful for air policy establishment to reduce air pollution and adverse health effects caused by PM2.5. To this end, it is necessary to establish reliable emission input data for air quality models based on air pollutants' emission inventory data. In this study, we examine the characteristics of major air pollutants emitted from various emission sources in the southeast region in Korea, one of the four regions being recognized as the air pollution is serious, using a gathered information on recent 10-year's air emissions. In addition, we search the points to be carefully considered for the development of the detailed modeling emission inventory necessary for the reliable predictions of PM2.5 in the Southeast region.
