Temperature dependence of emission product distribution from vaping of vitamin E acetate.

ABSTRACT: Nearly two years after vitamin E acetate (VEA) was identified as the potential cause of the 2019-2020 outbreak of e-cigarette, or vaping product-associated lung injuries (EVALI), the toxicity mechanisms of VEA vaping are still yet to be fully understood. Studies since the outbreak have found that e-liquids such as VEA undergo thermal degradation during the vaping process to produce various degradation products, which may pose a greater risk of toxicity than exposure to unvaped VEA. Additionally, a wide range of customizable parameters-including the model of e-cigarette used, puffing topography, or the applied power/temperature used to generate aerosols-have been found to influence the physical properties and chemical compositions of vaping emissions. However, the impact of heating coil tem
