Abstract
|
|
|
In the study of the harmful effects of outdoor secondhand smoke, the diffusion state may vary depending on environmental
factors such as the street, so to measure the actual outdoor air pollutants, an experiment was conducted after establishing
a cigarette smoke diffusion model base. As a result, when smoking and using all tobacco products, the concentration of fine dust (PM10) and ultrafine dust (PM2.5, PM1.0) was in the order of ‘liquid electronic-cigarette (e-cigarette)’ > ‘ordinary cigarette’ > ‘heating e-cigarette’, black carbon concentration and complex odor intensity were ‘ordinary cigarette’ > ‘liquid e-cigarette’ > ‘heating e-cigarette’ were the highest in the order. Therefore, even e-cigarettes, which are known to have relatively less irritating odors, emit harmful substances, so it is necessary to pay attention to the effects of second-hand smoke, especially indoor use of e-cigarettes.
