Potential effects from close and prolonged secondhand exposure to harmful vaping chemicals
Su W, Lin Y, Wong S, et al. Estimation of the dose of electronic cigarette chemicals deposited in human airways through passive vaping. Journal of Exposure Science & Environmental Epidemiology. 8 July 2021. 31; 1008–1016. https://www.nature.com/articles/s41370-021-00362-0
“For e-cigarette aerosol in the ultrafine particle regime, the deposited doses in the alveolar region were on average 3.2 times higher than those in the head-to-TB airways, and the deposited dose in the passive vaper’s airways increased when being closer to the active vaper.
With prolonged exposure and close proximity to active vapers, passive vapers may be at risk for potential health effects of harmful e-cigarette chemicals. The methodology developed in this study has laid the groundwork for future research on exposure assessment and health risk analysis for passive vaping.”
Comment: Secondhand vaping exposure is just beginning to be studied, but long-term lung effects are becoming more evident.
