Chungcheongnam-do has various emission sources, including large-scale facilities such as power plants, steel and petrochemical industry complexes, which can lead to the severe PM pollution. Here, we measured concentrations of PM₁₀, PM₂.₅, and its metallic elements at a suburban site in Taean, Chungcheongnam-do from September 2017 to June 2022. During the measurement period, the average concentrations of PM₁₀ and PM₂.₅ were 58.6 µg/m³ (9.6~379.0 µg/m³) and 35.0 µg/m3 (6.1~132.2 µg/m³), respectively. The concentration of PM₁₀ and PM₂.₅ showed typical seasonal variation, with higher concentration in winter and lower concentration in summer. When high concentrations of PM₂.₅ occurred, particulary in winter, the fraction of Zn and Pb components considerably increased, indicating a significant contribution of Zn and Pb to high-PM₂.₅ concentration. In addition, Zn and Pb exhibited the highest correlation coefficient among all other metallic elements of PM₂.₅. A backward trajectory cluster analysis and CPF model were performed to examine the origin of PM₂.₅. The high concentration of PM₂.₅ was primarily influenced by emissions from industrial complexes located in the northeast and northwest areas.
