초록 ▼

대기입자가 기후변화 및 지역적 대기질에 미치는 영향을 분석한 모델 예측에 상당한 불확실성이 포함되어 있다. 이것은 실제 대기에서 일어나는 이차유기에어로졸(SOA) 생성경로 중에 중요한 부분들이 대기화학모델에 적절히 반영되지 않았기 때문이다. 최근에 에어로졸의 표면이나 수용액상과 같이 에어로졸상에서 발생하는 화학반응에 의해 SOA 생성이 가능한 것으로 밝혀졌다. 발생량, 화학반응성, 반응 중간체에 근거할 때 생물기원 유기화합물(예, 이소프렌이나 테르펜류)과 인위적 오염물인 방향족화합물이 새로운 경로를 따라 지구적으로 상당한 양의 SO

Abstract ▼

There exist large uncertainties in model predictions for climate change and regional air quality. It might be caused by incomplete integration of secondary organic aerosol (SOA) formation in the atmospheric chemical model. Recently, SOA formation through chemical reactions on aerosol surface and in aerosol water was newly found. From the emission, reactivity, and reaction intermediate biogenic organics and anthropogenic aromatics are predicted to form substantial amount of SOA through the pathways. This research aims to experimentally develop a chemical mechanism, rate constants, yields for the aerosol-phase SOA formation and to evaluate atmospheric implication of the SOA formation by chemical model simulations using the experimental data.
