In order to understand the distribution characteristics of organic carbon (OC) and elemental carbon (EC) in PM2.5 in Changchun; China; PM2.5 samples were collected from April 2017 to December 2017 using the KC-120H particulate matter sampler; and the NIOSH 5040 method was used for determination. The results showed that the average concentration of PM2.5 in Changchun was 45.92 µg/m3 (45.92 ± 50.17), and the annual average concentrations of OC and EC ranged from 15.69 to 24.32 µg/m3 and from 1.38 to 2.33 µg/m3; respectively. The annual OC/EC ratio range was 8.08–15.44; with an average of 11.70. OC and EC concentrations in spring were the lowest; whereas higher levels of both OC and EC were found in winter. Significant correlations between OC and EC were found in the non-heating period; indicating that there was a consistent or similar source; whereas OC was non-significantly correlated with EC in the heating period; suggesting that contributions of OC were from unrelated combustion sources.
