Electronic cigarettes have become very popular recently and many people are using them as an alternative to regular cigarettes. Consumer advocates and health experts are now concerned about their safety.
Scientists have issued a report in Environmental Science & Technology, an ACS journal, showing new potentially toxic compound measurements in the vapor from e-cigarettes and noting how these levels are affected.
Vapor from 2 different vaporizers were analyzed by Hugo Destaillats and his team and they were filled with 3 various e-liquid refills. A number of components in the vapor including formaldehyde, acrolein and glycidol were found. Up until now glycidol has never been identified in e-cigarette vapor.
Glycidol has been listed as a probable carcinogen according to the World Health Organization while acrolein has been categorized as a powerful irritant. During testing, the heat and voltage emitted from a vaporizer with a single coil caused the level of acrolein to increase 10x while the aldehyde emissions were tripled per puff.
As well, the release of compounds that are potentially toxic went up with use. When glycerin and propylene glycol, 2 solvents that are used to make most e-liquids, undergo thermal decomposition, these toxic compounds are formulated.
