AB - To investigate characteristics and seasonal variations of carbonaceous species for PM2.5 in Seoul metropolitan area, Korea, we measured organic carbon (OC) and elemental carbon (EC) from January 2014 to December 2014 using a semi-continuous OC/EC Analyzer (Model-4, Sunset Lab.). Mean concentrations of OC and EC were estimated 4.1 ± 2.7 μg/m3 and 1.6 ± 1.0 μg/m3, respectively. The annual averaged OC/EC ratio was 2.9 ± 2.7. Concentrations of OC and EC comprised 13% and 5% of PM2.5 and the mass fraction of both was the highest in fall. OC and EC showed similar trend in seasonal variations. Concentrations of those showed a clear seasonal variation with the highest in winter and the lowest in summer. The correlations between the two were the best during the winter (r2 = 0.88). As results of carbonaceous species analysis, the dominant factor in view of fine particle (PM2.5) is primary emission source such as mobile, fossil fuel combustion during commute time(08:00~10:00 or 17:00~21:00) and winter season. Continuous monitoring of atmospheric carbonaceous species is essential to provide the science-based data to policy-maker establishing the air quality improvement policy.
