| 낮은 풍속과 높은 상대습도와 같은 기상 조건들은 어떤 역할을 하였나요? | 5의 고농도 사례의 원인으로 작용하였다. 낮은 풍속과 높은 상대습도와 같은 기상 조건들은 국지적으로 발생한 1차 오염물질들의 축적과 SO2와 NO2와 같은 기체상 전구물질들의 수용액상의 불균일 산화과정을 통한 2차 이온 성분들의 생성을 촉진시키는데 중요한 역할을 하였다. 더욱이 오후 시간에 관측된 O3의 최고 농도(79~95 ppb)는 광화학 산화반응을 통한 2차 에어 로졸 입자의 생성을 증가시켜 PM2. | |
| 광주 지역 PM2.5의 고농도 사례의 원인으로 작용한 요인들은 무엇인가요? | 측정 기간 중 기상자료, MODIS 위성 영상, 일기도, 공기 역궤적 계산 결과 등에 대한 분석 결과는 낮은 풍속과 높은 상대습도, 한반도 주변의 고기압 발달로 인한 대기 정체 현상, 중국에서 발생한 연무의 장거리 수송에 의한 국내 유입 등이 광주 지역 PM2.5의 고농도 사례의 원인으로 작용하였다. | |
| 국립환경과학원 호남권 대기오염집중 측정소에서 측정한 기간 중 PM2.5와 주요 화학적 성분들의 시간별 자료의 분석에 의하면 PM2.5의 고농도 현상은 무엇에 기인하였는가? | 5와 주요 화학적 성분들의 시간별 자료의 분석에 의하면 PM2.5의 고농도 현상은 2차 이온 성분들 (SO42-, NO3- 및 NH4+)의 농도 증가에 기인하였다. 그리고 유기 에어로졸 역시 PM2. |
