TLDR
The present study aims at the determination of the release of volatile organic compounds (VOC) and (ultra)fine particles (FP/UFP) from an e-cigarette under near-to-real-use conditions in an 8-m(3) emission test chamber.Abstract:
Electronic cigarette consumption (vaping) is marketed as an alterna- tive to conventional tobacco smoking. Technically, a mixture of chemicals containing carrier liquids, flavors, and optionally nicotine is vaporized and in- haled. The present study aims at the determination of the release of volatile organic compounds (VOC) and (ultra)fine particles (FP/UFP) from an e-ciga- rette under near-to-real-use conditions in an 8-m 3 emission test chamber. Fur- thermore, the inhaled mixture is analyzed in small chambers. An increase in FP/ UFP and VOC could be determined after the use of the e-cigarette. Prominent components in the gas-phase are 1,2-propanediol, 1,2,3-propanetriol, diacetin, flavorings, and traces of nicotine. As a consequence, passive vaping must be expected from the consumption of e-cigarettes. Furthermore, the inhaled aerosol undergoes changes in the human lung that is assumed to be attributed to deposition and evaporation.read more

TL;DR: It was found that the effect of flavorings in EC is clearly associated with pathogenicity at the molecular level and need of standardization of the usage of EC and its flavorings is urgently needed.

Effect of electronic cigarette (EC) aerosols on particle size distribution in indoor air and in a radon chamber
TL;DR: In this article, aerosols were generated from electronic cigarette (EC) and studied in the indoor air and in a chamber under controlled conditions of radon concentration, where the number concentration of the injected aerosol particles was between 40 000 and 100 000 particles/cm3.

It’s Just Steam: a qualitative analysis of New Zealand ENDS users’ perceptions of secondhand aerosol
TL;DR: Policy-makers face the challenge of correcting misperceptions about SHA without deterring full transition from smoking to ENDS use by including vaping in current smoke-free area policies; this measure would signal that SHA is not harmless, and could protect clean-air settings and reduce potential normalisation of vaping among non-smokers.

TL;DR: These self-reported findings suggest that use of ENDS in public places where cigarette use is prohibited is prevalent enough to be of concern for future regulation and enforcement efforts.

The effects of the European e-cigarette health warnings and comparative health messages on non-smokers’ and smokers’ risk perceptions and behavioural intentions
TL;DR: The effects of the EU TPD e-cigarette health warnings and a comparative harm message (COMP; developed specifically for this study) on smokers’ and non-smokers’ perceptions of harm, addictiveness and social acceptability of e-cigarettes are investigated.

Short-term Pulmonary Effects of Using an Electronic Cigarette: Impact on Respiratory Flow Resistance, Impedance, and Exhaled Nitric Oxide

TL;DR: In this paper, the authors found that using an e-cigarette for 5 min led to an immediate decrease in F ENO within the experimental group by 2.14 ppb (P 5.005) but not in the control group (P5.859), total respiratory impedance at 5 Hz in the experimental groups was found to also increase by 0.033 kPa/(L/s) (P,.001), and fl ow respiratory resistance at 5, 10, and 20 Hz also statistically increased.

TL;DR: The existing evidence on thirdhand smoke (THS) provides strong support for pursuing a programmatic research agenda to close gaps in current understanding of the chemistry, exposure, toxicology, and health effects of THS, as well as its behavioral, economic, and sociocultural considerations and consequences.

TL;DR: In this article, the authors determined nicotine and the nicotine related impurities, that is, cotinine, myosmine, anatabine, anabasine, and β-nicotyrine, in electronic cigarette cartridges, the liquid used to fill the cartridges, and from smoke generated using the electronic cigarette devices.
