摘要：

The concentrations of atmospheric black carbon (BC) and carbon monoxide (CO) in Byeongcheon were observed in winter, from January to February, 2018 and 2020 for annual comparison. We obtained the correlation between BC and CO. BC among PM2.5 and CO were measured using a multiangle absorption photometer and a carbon monoxide analyzer based on non-disperse infrared, respectively. BC to CO ratio (BC/CO) was used to estimate BC emission sources. The ABC/ACO ratio is also a representative indicator of aerosol generation characteristics and is compared with values from other places. ABC/ACO measured in 2018 and 2021 were 0.0067 mu g/m3/ppb and 0.0064 mu g/m3/ppb, respectively. ABC/ACO measured in 2018 was similar to that measured in 2021, which represents the generation characteristics of local pollutants. We obtained
