BC concentrations in Chungcheong Province, Korea for about eight months.
Comparison of BC with PM concentrations, wind velocity and wind direction.
The highest concentrations in spring and the lowest concentrations in fall.


Black carbon concentrations are closely related to global warming. To characterize atmospheric aerosols in Chungcheong Province, Korea, we measured the concentrations of black carbon for about eight months (September 2015 to April 2016), and compared them with PM10 and PM2.5 concentrations, as well as various meteorological parameters (e.g., wind velocity and wind direction). We used a multi-angle absorption photometer to measure black carbon, and the PM10 concentrations, PM2.5 concentrations, wind velocity, and wind direction were obtained from local monitoring stations. The highest and lowest PM10, PM2.5, and BC concentrations were observed in spring and fall, respectively. The high concentrations in spring and winter were likely due to the dominance of westerly winds transporting pollutants, while the low concentrations in fall were likely due to increased wind variations driving turbulent mixing. Overall, although BC concentrations exhibited direct proportional correlations with PM10 and PM2.5, the correlations were relatively low, likely driven by differences in the sources of these three atmospheric pollutants. These results help clarify the characteristics in BC concentrations over the Korean Peninsula.
