Exhaled e-vapor particles evaporate in seconds, study

Exhaled e-vapour product particles are actually liquid droplets that evaporate within seconds.


A new study recently demonstrated that exhaled e-vapour product particles are actually liquid droplets that evaporate within seconds. This is the first-ever study that investigates the dynamic properties of exhaled e-vapour aerosol particles.

Amid the examination, standard vapers utilized monetarily accessible shut and open framework vaping items while specialists estimated molecule fixations in the encompassing air. Dissimilar to for regular tobacco smoke, following prompt exhalation, researchers observed a fast decay and dissipation of the fluid vaporized beads, with levels coming back to foundation levels inside seconds. This was additionally seen under no room ventilation conditions, representing a worst case scenario.

Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures said, “No accumulation of particles was registered in the room following subjects’ vaping. This shows us how fundamentally different exhaled e-vapour particles are compared to those released when smoking conventional cigarettes, the latter of which linger in the air for longer periods of time.”

“Exhaled e-vapour aerosol particles have a different chemical composition to cigarette smoke and here we show the physical properties are also significantly different. This data adds to the growing body of evidence that vaping indoors is unlikely to pose an air quality issue.”

For both e-vapor products and ordinary cigarettes, the molecule fixations enrolled following each puff were in a similar request of extent. In any case, for e-vapor items the molecule fixation came back to foundation esteems inside a couple of moments; for ordinary cigarettes it expanded with progressive puffs, just coming back to foundation levels following 30-45 minutes.

The study entitled “Characterisation of the Spatial and Temporal Dispersion Differences between Exhaled e-cigarette mist and Cigarette Smoke,” was a collaboration between Kaunas University of Technology in Lithuania, EMPA (Swiss Federal Laboratories for Materials Science and Technology), ETH Zurich (Swiss Federal Institute of Technology) and Fontem Ventures.
