The observed annual mean PM<SUB>2.5</SUB> concentration in Jeonbuk in 2016 was 31 μg/㎥, twice higher than the national ambient air quality standard (15 μg/㎥. In this study, we analyzed the self- and inter-provincial contributions to the PM<SUB>2.5</SUB> concentrations in Jeonbuk by applying the Comprehensive Air quality Model with eXtensions with Particulate Source Apportionment Technology (CAMx-PSAT). The foreign contributions to the annual PM<SUB>2.5</SUB> concentrations ranged from 13.1 to 17.3 μg/㎥ in the fourteen local authorities in Jeonbuk. The domestic contributions in the local authorities calculated by adding the self-contributions and neighboring provincial contributions ranged from 5.9 to 12.0 μg/㎥. It implies that both the foreign and domestic emissions are important to alleviate the PM<SUB>2.5</SUB> concentrations in Jeonbuk. On top of the self-contributions of Jeonbuk, the contributions of Chungnam and Jeonnam in the vicinity played significant roles in determining the annual mean PM<SUB>2.5</SUB> concentrations in Jeonbuk. Meanwhile, it was estimated that daily PM<SUB>2.5</SUB> concentrations in Jeonbuk can be decreased by up to 15 μg/㎥ by controlling the nationwide emissions, especially when the daily PM<SUB>2.5</SUB> concentration is higher than 50 μg/㎥. It is noticed that the portion of inorganic ions in the domestic contributions increased as high as 90% when the daily mean PM<SUB>2.5</SUB> concentrations in Jeonbuk increased. Accordingly, reductions of the precursor emissions such as SO₂, NO<SUB>x</SUB>, and NH₃ would be effective to decrease the occurrences of high PM<SUB>2.5</SUB> days (>50 μg/㎥) in Jeonbuk. The site-by-site model performance evaluations show that there still exist uncertainties in the emissions used in this study. Therefore, prior to developing a comprehensive air quality improvement plan in Jeonbuk, the preparation of local emissions able to explain the details of local air quality is required.
