대기중 블랙카본과 일산화탄소 측정 = Measurement of Atmospheric Black Carbon and Carbon Monoxide

다국어 초록 (Multilingual Abstract)

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 ΔBC/ΔCO ratio is also a representative indicator of aerosol generation characteristics and is compared with values from other places. ΔBC/ΔCO measured in 2018 and 2021 were 0.0067 μg/m3/ppb and 0.0064 μg/m3/ppb, respectively. ΔBC/ΔCO measured in 2018 was similar to that measured in 2021, which represents the generation characteristics of local pollutants. We obtained BC/CO data to better understand BC emission characteristics in Byeongcheon area for the first time.

겨울철 충남 병천에서 대기중 블랙카본(BC) 및 일산화탄소(CO)를 측정하고 BC와 CO의 관계식을 도출하였다. 2018년 1월과 2월, 그리고 2021년 1월과 2월 BC와 CO의 농도를 40일 이상 연속 관측하였다. 초미세먼지(PM2.5) 중 BC는 다중각도흡수광도계로 측정되었고, CO는 비분산적외선흡수법 방식의 일산화탄소 분석기로 측정되었다. BC와 CO는 불완전연소의 산물이며 연소 배출의 지표이다. BC 대 CO의 비율(BC/CO 비)은 CO 배출에 기초하여 BC 배출을 추정하는 데 사용되었다. 또한, ΔBC/ΔCO 비를 구하여 다른 지역의 값들과 비교하였다. 2018년과 2021년에 측정된 ΔBC/ΔCO 비는 각각 0.0067 μg/m3/ppb 그리고 0.0064 μg/m3/ppb로 유사한 수준이었으며 측정지역의 오염물 발생 특성을 잘 나타낸다. 본 연구를 통해 병천 지역 BC 발생 배출특성을 이해하는 기초자료를 최초로 확보할 수 있었다.
