I am discussing this on various forums. THIS has been making the rounds in news etc. in the recent days:
Why toxic compound emissions vary in e-cigarettes
The study is at
http://pubs.acs.org/doi/abs/10.1021/acs.est.6b01741
But they want $40 for the "full" report.
I'd like to see the actual, full report since the report/abstract and the news citing the study are confusing and missing important details.
The study mentions how the amount of formaldehydes and other aldehydes etc. increases "with Volts" which is totally useless and actually "unscientific" since without the ohms mentioned and the actual devices they tested, volts doesn't mean anything!
It's clear and not exactly a secret that higher coil temps vapes more liquids, and also more aldehydes. It's also clear that gunked coils are releasing more dehydes. But the study doesn't mention measured coil temps and it's also not clear whether the statistics used, eg. for the max. amount of formaldehydes was measured using gunked/burned coils.
There is also a statistic/bars about the aldehydes emitted, but to me its totally useless since I don't know what a "tolerable" or normal/low level would be as compared to a high level of aldehydes.
** What irks me now is that there are discussions going on in forums etc. where people use the report to "prove that vaping is harmful"....but given how incomplete the study is...it doesn't help me in the slightest to either agree with them or prove them wrong. For example it may well be that subohm-devices and vaping at a certain Voltage at HIGH watts etc. releases a lot more aldehydes (due to coil temps) than, say, someone vaping at 15W.
One such study (not sure whether it's this one) also mentioned curiously how the amount of aldehydes measured was "significantly less" on dual coil devices....which I consider extremely interesting. I would want to know why.
