The Comprehensive Air quality Model with eXtensions with Particulate Source Apportionment Technology (CAMx-PSAT) was applied to quantitatively assess the major source regions and key air pollutants to increase PM<SUB>2.5</SUB> concentrations in Incheon for 2016. Emissions of PM<SUB>2.5</SUB> precursors, including primary PM<SUB>2.5</SUB>(PPM<SUB>2.5</SUB>), released from Incheon and its neighboring municipalities in the Clean Air Policy Support System 2016, were tagged and tracked to estimate the domestic contributions on a 3-km horizontally gridded modeling domain. The annual mean PM<SUB>2.5</SUB> self-contribution of Incheon was 5.2 ㎍/㎥ while the PM<SUB>2.5</SUB> contribution of Seoul, Gyeonggi, and Chungnam to Incheon was 0.5, 2.5, and 2.2 ㎍/㎥, respectively. Emissions from the rest of South Korea account for 1.5 ㎍/㎥ of the annual mean PM<SUB>2.5</SUB> in Incheon. When the self-contribution was divided into the individual emission species, PPM<SUB>2.5</SUB>(2.3 ㎍/㎥) showed the highest contribution followed by NH₃(2.2 ㎍/㎥), NO<SUB>x</SUB>(0.64 ㎍/㎥), and SO₂(0.5 ㎍/㎥). The simulation with the CREATE 2015, the regional emissions inventory for outside South Korea, showed that foreign contributions to annual mean PM<SUB>2.5</SUB> concentrations in ten local authorities inside Incheon are consistent, ranging from 19.0~21.1 ㎍/㎥, while the relative foreign contributions varied in the range of 57~76%. The apparent spatial difference (19%) in the relative foreign contributions is mainly driven by large spatial variances of the domestic PM<SUB>2.5</SUB> contributions in the ten local authorities. The domestic contribution was as low as 6.7 ㎍/㎥ in Ganghwa-gun, an insular local authority of Incheon, while it was as high as 14.7 ㎍/㎥ in Michuhol-gu, a highly populated inland local authority. The results imply that international and interprovincial cooperation is essential to abate PM<SUB>2.5</SUB> concentrations in Incheon.
