In this study, source-contributions on PM<SUB>2.5</SUB> concentrations in five regions of Busan and eighteen local authorities of Gyeongnam was estimated with the Comprehensive Air quality Model with eXtensions with Particulate Source Apportionment Technology (CAMx-PSAT) for the whole year of 2016. The domestic contributions to the annual mean PM<SUB>2.5</SUB> concentrations in Busan and Gyeongnam were 8.5 μg/m³ and 7.5 μg/m³, respectively. In Gyeongnam, the provincial selfcontribution to the annual mean PM<SUB>2.5</SUB> was the higher (2.8 μg/m³) than that from the individual neighboring province. The contribution of Jeonnam, Gyeongbuk, Chungnam, and Ulsan to the annual mean PM<SUB>2.5</SUB> in Gyeongnam were 1.2, 0.8, 0.6, 0.5 μg/m³, respectively. In Namhae-si and Hadong-gun, locating in the western part of Gyeongnam and adjacent to Jeonnam, the contributions of Jeonnam to the PM<SUB>2.5</SUB> concentrations were higher than the provincial self-contribution. In Busan, the provincial self-contribution to the annual mean PM<SUB>2.5</SUB> was 3.4 μg/m³. In particular, the self-contribution in the central western region, where Busan port is located, was highest among the five regions in Busan. However, the over-predicted NO₂ and SO₂ concentrations in this region can be in part due to the overestimations of NO<SUB>x</SUB> and SO₂ emissions used in this study (i.e., Clean Air Policy Support System 2016). Among the neighboring provinces, the contribution of Gyeongnam showed the highest to annual mean PM<SUB>2.5</SUB> in Busan for the year, followed by Ulsan, Gyeongbuk, and Chungnam. In Busan, the control measures on the Primary PM<SUB>2.5</SUB> emissions are recommended to mitigate the PM<SUB>2.5</SUB> concentrations due to the high emission-toconcentration conversion rate and the self-contribution.
