Potential Impacts of Vaping on Occupants of the Indoor Environment

The rapid growth of e-cigarette use has raised questions about their impact on the indoor air quality of offices and public spaces.  The dearth of available information reveals them to be sources of volatile organic compounds (VOCs) and particulate aerosols that have not been fully characterized.  E-cigarettes primarily emit propylene glycol, glycerin and nicotine in addition to diethylene glycol, nitrosamines, 1,2-propanediol, acetic acid, acetone, isoprene, formaldehyde, acetaldehyde, propaldehyde and various flavoring compounds into the indoor air at varying levels.
