Elemental carbon (EC) and organic carbon (OC) mass concentrations in PM2.5 were measured from March through October 2015 in Taehwa Research Forest (TRF). The concentration of carbon in the TRF was 3.4 g/m3 and the concentration of EC was 1.4 g/m3. Also the concentration of OCsec was the highest at 2.84 g/m3 in the summer and the lowest at 1.66 in the spring. The ratio of the secondary generation OC in the total OC was the highest at 62% in the summer. Monthly OC concentration was the lowest at 2.38 g/m3 in April and the highest at 6.60 g/m3 in July. In case of EC concentration was the lowest in April (0.98 g/m3) and the highest in July (3.41 g/m3). The OC/EC ratio showed the lowest ratio in March and the highest rate in September. It is suggested that the secondary generation reaction of OC component was active due to sufficient irradiation amount in summer.
