Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes, according to a recent study by the Korea Disease Control and Prevention Agency.

Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes: study

By photographing smoke and aerosols emitted from cigarettes to analyze their chemical composition, the results showed that liquid-based e-cigarettes emitted 172,845 micrograms (㎍) of ultrafine dust per 0.2 grams of liquid, 12 times more than what was emitted by non-electronic cigarettes.

 

Meanwhile, heated e-cigarettes emitted 3,100 ㎍ of ultrafine dust per cigarette, lower than emissions from non-electronic cigarettes.

 

Over a three-minute period, the ultrafine dust emitted by liquid-based e-cigarettes spread as far as 10 meters, heated e-cigarettes to between 6 and 7 meters and non-electronic cigarettes to 3 meters.

 

The study also revealed that black carbon, a chemical related to the automobile emissions stains, is released by all three types of cigarettes.

 

The highest black carbon levels were from non-electronic cigarettes, which were also present in liquid-based e-cigarettes (98.8 ㎍ per piece) and heated e-cigarettes (11.41 ㎍ per piece).
