Fontem Ventures investigates indoor e-cig vapor properties

On April 20, a poster entitled “Aerosol concentration variations in a room during use of an e-cigarette” was presented at the 4th Workplace and Indoor Aerosols conference in Barcelona by Dainius Martuzevicius, Associate Professor at Haunas University of Technology (Lithuania).

In addition to Fontem Venture and SEITA-Imperial Brands, the consortium also combines expertise’s from:

  • Kaunas University of Technology (Lithuania),
  • EMPA, Swiss Federal Laboratories for Materials Science and Technology,
  • ETH, Swiss Federal Institute of Technology (Zurich).

 

The authors argue that the study may have a positive implication for continued use of e-cigarettes in indoor areas because it shows “for the first time exhaled e-cigarette particles are liquid droplets that evaporate rapidly upon exhalation”.

Their results indicate that the concentration of particles may reach several millions of particles per cubic centimetres in the room where the experiment is carried out but the concentration also decreases very quickly, within a few seconds, to return to background level. The concentration decreases as a function of the distance between the emitter and the analytical sampler and no accumulation of particles was registered in the room during 30 min period after e-cigarette use.

 

“This study shows that e-cigarettes – similar to other consumer aerosol-based products – release liquid primary particles into the air that disappear extremely quickly” – G. O’Connell
