미세먼지 농도 배출특성에 영향을 미치는 요인은 무엇인가? | 배출량 - 농도의 비선형성과는 별개의 문제로 점, 선, 면배출원에 따라 배출특성이 달라진다. 예를 들어 배출이 되는 지점의 수평, 수직 위치 등 공간적 특성, 배출 시간적 특성 (예를 들어; 계절, 요일, 오전/오후 등), 배출되는 물질의 화학 조성, 주변 배출 및 다른 대기오 염물질 농도 등 많은 요소가 농도에 영향을 미친다.따라서 동일한 크기의 삭감 배출량에 대한 PM 2. | |
실효성 있는 PM2.5농도 개선계획 수립을 위해 필요한 것은 무엇인가? | 실효성 있는 PM2.5농도 개선계획 수립을 위해서는 목표 농도를 만족할 수 있는 삭감 배출량이 확보 되어야 하는 동시에, 저감대책별 투입비용 대비 농도 개선을 평가할 수 있는 비용효과 (cost-benefit) 분석이 필요하다(Kwon et al., 2016). | |
저감대책별 농도저감 및 비용효과 평가를 위해서는 무엇이 필요한가? | 저감대책별 농도저감 및 비용효과 평가를 위해서는 각각의 저감대책이 PM2.5농도 변화에 얼마나 영향을 주는지에 대한 분석이 요구된다. 이러한 저감대책 - 배출량 - 농도로 이어지는 일련의 분석과정에서 삭감 배출량은 계획수립 단계에서 추정이 비교적 쉽게 가능하나, 삭감 배출량에 의한 PM2. |
