Abstract Number: 417 Working Group: Aerosol Exposure
Abstract Electronic cigarettes are relatively new devices, are rapidly increasing in their market adoption and yet have not been thoroughly characterized. These factors force regulators to make decisions regarding their use with minimal information. In this work, we will describe a device that has been built to operate the e-cigs at adjustable power, flow, and time. We have characterized the aerosol produced using this device and a commercially available e-cigarette. Particles were sized using a Scanning Mobility Particle Sizer and an Engine Exhaust Particle Sizer, due to the rapid response time. The aerosol was sized as a function of several different parameters such as filament power, e-liquid composition, and humidity of the eluent environment. Mass balance of the e-liquid with the particle and gas phase also has been explored. Gas chromatography-mass spectrometry has been used to characterize the products of vaping and their distribution in the aerosol. Results indicate that the factors investigated have a significant impact on the resulting aerosol size distributions, total mass, and ultimately deposition/absorption in the human airway.
