미세먼지가 위험한 이유는 무엇인가? | 미세먼지는 폐기능 저하, 심혈관계 질환, 만성 기관지염, 천식 등을 유발하는 등 인체 위해성이 높을뿐만 아니라, 지구에 도달하는 태양빛을 흡수하거나 산란시켜 기후변화에도 영향을 주고 시정을 악화시키는 대표적인 대기오염물질이다. 특히 초미세먼지(PM2. | |
PM2.5의 탄소성분은, 분석 방법에 의해 무엇으로 구분되는가? | 5의 주요 구성성분은 황산염, 질산염 등 수용성 무기성분이약 50%, 탄소성분이 약 30%, 그리고 나머지는 미량 금속성분 및 기타 미지성분인 것으로 조사되었다(MOE, 2013). 탄소성분은 분석방법에 의해 원소탄소(elemental carbon, EC)와 유기탄소(organic carbon, OC)로 구분된다(Park et al., 2005; Birch, 1998). | |
초미세먼지의 위험성은? | 특히 초미세먼지(PM2.5)는 호흡기의 가장 깊은 곳까지 침투하여 혈관으로 이동하기 때문에 호흡기질환 및 심혈관계 질환을 유발하며, 대기 중 PM2.5의 농도가 호흡기계와 심혈관계 질환의 유병률 및 사망률과 뚜렷한 상관관계가 있다는 사실은 많은 연구에서 밝혀졌다(Song et al., 2016). |
