궐련담배 연기 응축물의 pH에 관한 연구

Study on the pH of the Particulate matter in Cigarette Smoke

Cigarette smoke is an aerosol consisted of both vapor and Particulate phases. In this study, the smoke condensates from several blended cigarettes were dissolved in water and the pH of the resulting solution was determined. The pH of the smoke condensate decreased with increase of puff number. In the beginning the pH decreased a little, while decreased remarkably from puff No.5 to puff No.10.
