Electronic Cigarettes and Indoor Air Quality: A Simple Approach to Modeling Potential Bystander Exposures to Nicotine

Introduction:
This article presents a simplified model for determining the potential contribution of a single puff from an electronic cigarette (e-cigarette) to indoor air quality and the cumulative effect of vaping over time. The model considers aerosol propagation, dilution, and extraction, and is used to simulate the user and bystander exposure in a virtual office scenario. The model is then validated by comparing its results with published experimental studies.

Key Points:

* The model is based on physical principles, considering aerosol propagation, dilution, and extraction to determine the potential contribution of a single puff from an e-cigarette to indoor air quality.
* The model is validated by comparing its results with published experimental studies, showing good agreement.
* The model can be used to simulate the cumulative effect of vaping over time in a virtual office scenario.
* The virtual office scenario consists of an e-cigarette user and a non-user working in the same space.
* The main message of the text is that with some additional refinements, this approach can be a cost-effective and rapid way of assessing the potential exposure of bystanders to exhaled e-cigarette aerosol constituents.

Main Message:
The model presented in this article is a valuable tool for assessing the potential exposure of bystanders to exhaled e-cigarette aerosol constituents. With some additional refinements, this approach can be a cost-effective and rapid way of evaluating the indoor air pollution impacts of e-cigarette use, and thus estimating a bystander's potential exposure. This information can inform evidence-based regulations for e-cigarette use in indoor spaces.
