Passive exposure to nicotine from e-cigarettes

Introduction:
This text discusses a study that aimed to evaluate the quality control analysis of e-cigarette liquid refills and passive exposure to nicotine from cigarette and e-cigarette smoking. The study used ion mobility spectrometry (IMS) to determine nicotine in various samples, including oral fluids and exhaled breath.

Key Points:

* The study used IMS as an alternative analytical technique for nicotine determination in various samples.
* a simple method based on liquid-liquid microextraction (LLME) of samples was developed and evaluated for quantification of nicotine in oral fluids and exhaled breath.
* The study evaluated the nicotine content of 33 commercial e-cigarette refill liquids and found that the declared and measured nicotine content were statistically comparable for most samples. however, three samples provided results differing in approximately 900% with declared value, and two zero-level nicotine liquid refills contained nicotine.
* Passive exposure to nicotine from cigarette and e-cigarette smoking was evaluated by determining nicotine levels in oral fluids and exhaled breath of active and passive smokers.
* The study found that the exhaled breath of e-cigarette users contained tobacco-specific nitrosamines (TSNas), formaldehyde, glyoxal, methylglyoxal, acrylamide, acrolein, nicotine, and other volatile organic compounds (VOCs), suggesting that passive exposure to e-cigarette vapors should be a matter of concern.
* The impact of e-cigarette vaping on indoor air quality and passive exposure was studied, and it was found that VOCs, ultrafine particles (UFPs), polycyclic aromatic hydrocarbons (Pahs), carbonyls, and metals were released during e-cigarette smoking.

Main Message:
The study highlights the importance of quality control analysis of e-cigarette liquid refills and the potential risks of passive exposure to nicotine and other harmful compounds from cigarette and e-cigarette smoking. It suggests that further research is needed to evaluate the long-term health effects of e-cigarette use and passive exposure to e-cigarette vapors. additionally, regulations and policies should be implemented to minimize the potential risks associated with e-cigarette use.
