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.

The main purpose of this study was to analyze the Korean PM2.5 emissions according to the past, present, and future energy mix scenarios from 1970 to 2035, with the aim of identifying a sustainable, future environmentally friendly energy mix scenario for Korea related to PM2.5 emissions. To calculate the PM2.5 emissions according to an energy mix plan, we assumed two scenarios: (1) Scenario 1 is based on an energy conversion scenario established by the Korean government’s 7th electric power demand supply program; and (2) Scenario 2 is enhancement of fuel cell usage. In Scenario 1, filterable PM2.5 (FPM2.5) emission was calculated as 61,158 ton/year, which includes contributions of anthracite (46.8%), petroleum (39.7%), natural gas (LNG) (10.0%), and LPG (0.1%). In Scenario 2, FPM2.5 emission was calculated as 36,917 ton/year, which includes contributions of petroleum (47.8%), anthracite (40.3%), bituminous coal (10.1%), and LNG (1.7%). Thus, we concluded that the FPM2.5 mitigation effect from fuel cell policy enforcement is about 38.13% higher than the Korean national energy conversion policy. PM2.5 (FPM2.5 + condensable PM2.5 (CPM2.5)) emissions dramatically increased in both energy mix scenarios so that CPM2.5 should be considered when estimating PM2.5 emissions and PM2.5 reduction.
