EC가 중요한 대기오염 물질의 지표로 활용되는 이유는? | , 2007; Ramanathan and Carmichael, 2008; 임세희 등, 2010). 또한 EC는 OC에 비해 대기 중에서의 체류시간이 길며, 인위적인 일차 배출원이 주발생원이라는 특성 때문에 중요한 대기오염 물질의 지표로 활용되고 있다(He et al., 2004). | |
전 지구적 혹은 지역적인 기후변화에 대한 탄소성 입자의 역할과 특성을 파악하는 선행연구들의 한계점은 무엇인가? | 선행연구들은 대부분 여지에 24시간 동안 시료를 채취하여 하루 단위로 탄소성분을 분석하였기 때문에 반휘발성 물질들의 질량농도를 정확히 측정하는데 한계가 있으며, 시간변화에 대한 측정자료를 도출하는 것이 불가능하였다(Pang et al., 2001; 이시혜 등, 2008; 임세희 등, 2010). 또한 준 실시간 분석장비를 사용한 경우에도 단기간의 분석결과로 인해 장기적인 농도변화 및 시간변화에 대한 대표성 있는 자료 획득에 어려움이 있었다(Bea et al., 2007; Lee et al. | |
탄소성 유기분진이 미치는 영향은 무엇인가? | , 2009; 한지현 등, 2013). 탄소성 유기분진은 시정거리(visibility) 감소, 기후 강제력(climate forcing) 등의 변화에 크게 기여하고, 인체에 악영향을 미치는 것으로 알려져 있다(Raes et al., 2000; Jacobson, 2001; Leck et al. |
