The relative humidity of test ambient air was elevated at 59~64% or 84~88% by adding water vapor. The aerosol number size distribution and the concentrations of O₃, NO, NO₂, and SO₂ were measured during the experiments. The O₃, and NO₂ gases were well reacted with the water vapor at high relative humidity of 84~88%, and the reaction rates of these gases seemed to be decreased at low relative humidity of 59~64%. The formation and condensational growth phenomena of ambient aerosols by water vapor reactions were observed in a Teflon bag, depending strongly on the initial particle size distribution. The water vapor reactions might be affected by the contents of oxidants produced by photochemical reactions under sunlight. 한국대기환경학회 스모그 챔버에서 수분 반응에 의한 대기 에어로졸의 생성 및 성장 Formation and Growth of Atmospheric Aerosols by Water Vapor Reactions in an Indoor Smog Chamber Article 2 한국대기환경학회지, v.20, no.2, pp.161 - 174 한국대기환경학회지 20 2 161 174 kci ART001116409 Water vapor Aerosol Smog chamber Condensation Relative humidity
