Single particle soot photometer (SP2) is an advanced instrument capable of real-time measurement of concentration, coating thickness, and size distribution of individual BC particle using laser-induced incandescence. So far, there have been insufficient studies examining the real-time characteristic...

백령도에서의 PM2.5 주요성분은 무엇인가? | 5 측정 결과 중 백령도에서의 PM2.5 주요성분은 황산염, 질산염 및 탄소성분이며, 그중 탄소성분이 전체 PM2.5 질량의 30% 이상을 차지하는 것으로 보고하였고 (NIER 2011; NIER 2010; NIER 2009), 기류가 중국 내륙을 거쳐 유입된 경우에 농도가 증가하는 것으로 보고하고 있다. | |
블랙카본은 어떻게 발생하는가? | 블랙카본 (Black Carbon, BC)은 화석연료, 생체소각 등의 연소과정에서 불완전연소로 발생하며, 대기 중에서 광흡수 및 소멸작용을 통해 지구 알베도에 영향을 미치고 시정감소를 초래한다 (Gebhart et al., 2001; Myhre et al. | |
광 흡수법과 NIOSH5040 프로토콜을 이용한 열 광학적 투 과법의 한계점은 무엇인가? | BC를 정량화하는 방법에는 여러 측정 방법들이 개발되어 사용 중에 있으며 대표적으로 입자 채취 전·후의 빛의 감쇄 차이를 이용해 BC 입자의 질량을 측정하는 광 흡수법과 NIOSH5040 프로토콜을 이용한 열 광학적 투 과법 (Thermal optical transmission)이 있다. 하지만 이러한 측정 방법은 채취 전후의 필터 빛 감쇠 차이, 고온을 이용하여 열-탈착시켜 측정하는 방법으로 필터에 채취된 벌크형태의 BC 농도에 대한 정보만 제공할 뿐 입경분포, 단일 BC 물질의 코팅두께 등의 BC의 최신정보를 실시간으로 측정하는 것은 어렵다 (Gao et al., 2007; Schwarz et al. |
