1. Some E-Cigarettes May Emit More Toxins Than Others Study

Are E-Cigarettes Harmful?

While prior reports have discovered that e-cigarettes emit toxic compounds, a new study from Lawrence Berkeley National Laboratory (Berkeley Lab) has identified the source of those emissions and has shown how temperature, form, and age of the gadget play a role in emission stages.  These information is valuable to manufacturers and regulators who are seeking to minimize the wellness effects of these devices.

This study, which was released in Environmental Science and Technology, discovered that the thermal decomposition of propylene glycol and glycerin, the two solvents discovered in most “e-liquids ” (the substance which is vaporized by the e-cigarette), leads to the emission of toxic chemical substances such as acrolein and formaldehyde.

According to one of the authors, Berkeley Lab researcher Hugo Destaillats, Advocates of e-cigarettes say emissions are much lower than from conventional cigarettes, so you’re better off using e-cigarettes. I would say, that may be true for certain users–for example, long time smokers that cannot quit–but the problem is, it doesn’t mean that they’re healthy. Regular cigarettes are super unhealthy. E-cigarettes are just unhealthy.

In this study, “Emissions from electronic cigarettes: Key parameters affecting the release of harmful chemicals,” the researchers simulated vaping utilising three varieties of e-liquids in two specific vaporizers operated at various battery energy settings. The two e-cigarettes have been really distinct, one particularly low priced with one heating coil, the other more highly priced with two heating coils in parallel. The researchers used gas and liquid chromatography to investigate what was in the vapor, looking on the first puffs along with the later puffs after the device heated up and reached a regular state.

Not All E-Cigarettes Are Equal

One finding was once that the first and last puffs produced various emissions. Utilizing a customized-built vaping equipment emulating realistic vaping habits, researchers drew on the e-cigarette via taking puffs lasting 5 seconds each for 30 seconds. They then found out that vapor temperature rose rapidly within the first 5 to 10 minutes until achieving a regular state temperature at across the twentieth puff.

Correspondingly, emission levels between the primary few puffs and the regular state expanded through a factor of 10 or more in some instances, depending on the device, the battery voltage, and the emitted compound. For example, for acrolein, a severe eye and respiratory irritant, a single-coil e-cigarette operated at 3.8 volts emitted 0.46 six micrograms per puff in the first 5 puffs, however at the regular state it emitted 8.7 micrograms per puff.

According to another Berkeley researcher Lara Gundel, When you apply the same voltage to the double-coil e-cigarette you see a lot less emissions. We think it has to do with lower temperatures at each of the coil surfaces.”

For assessment, traditional cigarettes emit 400 to 650 micrograms of acrolein per cigarette, accounting for both mainstream and sidestream emissions. Assuming 20 puffs on an e-cigarette is identical to smoking a traditional cigarette, Gundel said, the total emissions of acrolein for an e-cigarette are around 90 to 100 micrograms.

Separately, to test results as a result of device aging, researchers used a single gadget over 9 consecutive 50-puff cycles without cleansing. Once more, emissions of formaldehyde, acetaldehyde, and acrolein, which are all either cancer agents or respiratory irritants, increased with usage.

The researchers concluded in their paper, This effect is consistent with the buildup of polymerization byproducts on or near the coil leading to accumulation of the sort of residues that are often referred to in the blogosphere as ‘coil gunk’ or ‘caramelization.’ Heating these residues would provide a secondary source of volatile aldehydes.”
