Study on the contribution ratios of particulate matter emissions in differential provinces concerning condensable particulate matter

This study attempted to reanalyze the emission property of particulate matter and set up the strategy on the emission reduction of particulate matter by considering the condensable particulate matter additionally as the total particulate matter together with filterable particulate matter. For this, total suspended particles and particulate matter 2.5 emitted in 2013 were selected as pollutants. Fuel classifications were divided into major and minor categories, and the sources were divided into major, medium, and minor categories. Three provinces were set as administrative areas: Gyeonggi-do, Chungcheongnam-do, and Jeollanam-do. The condensable particulate matter emission factors used were obtained from National Institute of Environmental Research. The condensable particulate matter emission factors of liquefied natural gas, diesel, and bunker C oil were measured in boilers with no preventive facilities, and the coal power plant emission factor was obtained at the end of the prevention facility. The condensable particulate matter emissions were calculated by multiplying the particulate matter 2.5 filterable particulate matter emissions by the ratio of the condensable particulate matter emissions to the filterable particulate matter of the National Institute of Environmental Research data. Different patterns of emission sources were observed for each province depending on the consideration of condensable particulate matters. Considering only the filterable particulate matters, the proportion of mobile pollutants was high. On the other hand, considering the condensable particulate matters, the contribution of the nonindustrial combustion category emissions using gaseous fuels, such as city gas, increased in the metropolitan area, whereas the contributions of the manufacturing combustion category emissions increased in the nonmetropolitan areas. Therefore, in the case of collecting energy facilities and the manufacturing burning facilities planned in the local cities in Korea, it is necessary to consider the filterable particulate matter, and condensable particulate matter emission amount.
