To improve understanding of the physico-chemical characteristics of aerosols in the national park and comparing the air pollution between national park and the urban area nearby national park, the aerosol characterization study was conducted in Bukhansan National Park, Seoul, from July through September 2017. Semi-continuous measurements of PM<SUB>2.5</SUB> using PILS (Particle Into Liquid System) coupled with IC (Ion Chromatography) and TOC(Total Organic Carbon) analyzer allowed quantification of concentrations of major ionic species (Cl<SUP>-</SUP>, SO₄<SUP>2-</SUP>, NO₃<SUP>-</SUP>, Na<SUP>+</SUP>, NH₄<SUP>+</SUP>, K<SUP>+</SUP>, Mg<SUP>2+</SUP> and Ca<SUP>2+</SUP>) and water soluble organic carbon (WSOC) with 30-minute time resolution. The total mass concentration of PM<SUB>2.5</SUB> was measured by T640 (Teledyne) with 5-minute time resolution. The black carbon (BC) and ozone were measured with a minute time resolution. The timeline of aerosol chemical compositions reveals a strong influence from urban area (Seoul) at the site in Bukhansan National Park. Inorganic aerosol composition was observed to be dominated by ammoniated sulfate at most times with ranging from 0.1~32.6 μg/m3 (6.5~76.1% of total mass of PM<SUB>2.5</SUB>). The concentration of ammonium nitrate, a potential indicator of the presence of local source, ranged from below detection limits to 20 μg/m3 and was observed to be highest during times of maximum local urban (Seoul) impact. The total mass of PM<SUB>2.5</SUB> in Bukhansan National Park was observed to be 10~23% lower than the total mass of PM<SUB>2.5</SUB><SUB></SUB> in urban area (Gireum-dong and Bulgwang-dong, Seoul). In general, ozone concentration in Bukhansan National Park was observed to be similar or higher than urban sites in Seoul, suggesting additional biogenic VOCs with NO<SUB>x</SUB> from vehicle emission were to be precursors for ozone formation in Bukhansan National Park.
