New studies find carcinogens in vg and pg at high temps, even in tootle puffers

[Katya]

Thinner wire is harder to keep in optimal operating ranges.

I'd say impossible (without TC). After 4 or 5 seconds, and with poor wicking and poor airflow, you're reaching temps that are clearly dangerous--as evidenced by burnt filler surrounding a heating coil.

 

[tiburonfirst]

Could be that's the start of formaldehyde being formed.

or could be you taste it once the process is well underway

 

[Steamix]

just a thought: Silica wicks would be the way to go? They do not burn.

Might have to get out the little bit I have from years ago....

Maybe the other way round :

Cotton and rayon burn/melt through at fairly low temps.
So they might well be the pauper's TC
If your cotton or rayon wick decides to quit, you're running your juice too hot.

Well here is something new to add to the mix.
Study titled “Benzene formation in e-cigarettes” found that air has more benzene than e-cigs
Good news for a change.

 

[Eskie]

Now benzene is one really bad chemical. I'd rather purposely inhale formaldehyde over benzene.

 

[tj99959]

Well here is an interesting question then.

If e-cig vapor has less benzine than air .... where did the benzine go?

It is the black stuff in the wick.

Last I heard was Florida, but it will come back to the North in late April.

Maybe test in a vacuum running say pure argon instead of air. While standing on a barrel of VG.

But yeah, if it in fact is lower than plain old air there is a flaw in the test method that requires clarification. That link was not to the original study but an interpretation of it, so it might not be so clear cut on that comparison. Still, benzene is just plain not good for you.

Here are all the data from the USC study, including Compounds, Outdoor air, e-Cigarette, and normal cigarette.http://www.rsc.org/suppdata/em/c4/c4em00415a/c4em00415a1.pdf

For your convenience, listed below are the amounts of Cr, Ni, Pb, Zn and Al in outdoor air vs e-cigarette vapor:

Cr: 5.53 vs 4.22
Ni: 5.57 vs 6.14 (+/-2.9)
Pb: 13.28 vs 9.85
Zn: 54.31 vs 56.08 (+/- 21 [sic])
Al: 333.27 (±62.93) vs 161.43 (±71.35)

So, vapor is actually healthier, per this study, than the air we breathe here in SoCal.

The PG/VG is sterilizing the air that we breathe. That's a GOOD thing!

 

[Robino1]

Oh! Another thought, more Californians should vape...it might help the air quality in the state.

 

[Zutankhamun]

On a lighter note.

Ive just found out how to get the degree symbol

232°C eh?

Im so simple and easily amused

Edit; Lol. Sorry. My contribution has gone even further downhill...

When people ask what power level they should use with a setup they are always advised to start low, and keep raising the power until it starts to taste bad, then drop it back a bit. That bad taste when the power is a little too high is nothing like a dry hit but it does taste noticeably bad. Never really considered what it was. Could be that's the start of formaldehyde being formed. If you had asked me a week ago I would have said it was just slightly burned juice.

And your Answer last week would probably be just as Valid Then as it is Today.

Because that Bad Taste is most likely something undergoing a Thermal Breakdown. Be it VG or PG or maybe a Flavoring(s) or Sweetener(s).

That's why None of the stuff in this threads Scares me.

Because I don't look at my Mod as Producing Harmful Compounds. I look at my Mod as Filtering Out the Harmful Compounds from the Ambient Air.

Well who'd a thought that a vaping forum would have me researching the chemical formula that has been derived when applying heat and oxygen at a particular °C/F to find out the rate and temp needed to combust (or close to) vegetable glycerin and/or propylene glycol.

And they said it was nicotine we needed to worry about 'pfft'

wouldn't vape displace the air thus diluting the amount in test result?

Oh come on now, we're not letting any logic infiltrate here!

my bad.
ill just waddle away
til the very next day

In case you're not joking (always a possibility ), they test ambient air before they test the vapor.
