Acrolein is the main compound formed from the combustion of glycerine (the most popular carrier solvent for vaping nicotine)
Acrolein was one of the major cancer causing components of cigarttes that caused worry in the health industry. Vaping can introduce 40-300x the
amount of Acrolein than standard tobacco! The amounts estimated by the "vaping" (E-cig" industry) state that their product only generated "negligible
amounts" of Acrolein at less than 10mcg) per puff (that is 1/100th of a milligram). The problem is how do you measure a "puff". Does an Ecig give
300 puffs of 5,000 puffs? I can attest that a normal user gets about 10% of the "puffs" of what they say they should, so the measurements are skewed
to make levels look smaller.
Also, if the amount of glycerin that is burnt in an ecig is converted to Acrolein, than these numbers are off by a factor of 20-50x! IDK what they
are staying the glycerin is being converted to when it comes into contact with the heating element, but if it is something non-toxic, then there has
been a major breakthrough in chemistry and it would change the world of renewable energy (as glycerine is a major byproduct and there is a huge glut
of it dropping the price to $.02 - $.08 per lb - because it can't be burnt cleanly due to Acrolein production.
The presence of Acrolein also effects the bladder, urniary tract, kidneys causing all kinds of problems from cysts to chronic disease.
Acrolein - Boiling point - 127 degrees F - Flash point temp - NEGATIVE 15 degrees F! Autoigniton temp is 532 deg F. This means if vapors are present
at -15F and a spark is present it will flash ignite. If the temp rises to 532F it will spontaneously combust - At these temps the compound would be a
vapor (hence the "Vaping"). Wiki states the following under Hazard Warnings: Highly poisonous. Causes severe irritation to exposed membranes.
Extremely flammable liquid and vapor. Acrolein is toxic and is a strong irritant for the skin, eyes, and nasal passages.
The WHO suggests a "tolerable oral acrolein intake" of 7.5 μg per day per kg of body weight. OSHA has set a permissible exposure limit at 0.1 ppm
(0.25 mg/m3) at an eight-hour time-weighted average. Acrolein acts in an immuno suppressivemanner and may promote regulatory cells,
thereby preventing the generation of allergy on the one hand, but also increasing the risk of cancer.
Below are stats from Wiki
LD50/50 (median concentration) - the 50/50 means that 50% of those exposed to this level will die, the others live, so numbers lower than this can
also cause death but it is a good reference number for toxicity.
875 ppm (mouse, 1 min)
175 ppm (mouse, 10 min)
150 ppm (dog, 30 min)
8 ppm (rat, 4 hr)
375 ppm (rat, 10 min)
25.4 ppm (hamster, 4 hr)
131 ppm (rat, 30 min)
LCLo (lowest published)
674 ppm (cat, 2 hr)
Glycerine/glycerol - boiling point - 554 degrees F -
Propylene Glycol (PG) - boiling point (vaporization point) 370degrees F produces
Other products from vaping
Acetaldehyde - carcenogen
Formaldehyde - irritant to mucous membranes, throat, lungs, sinuses, eyes. Can cause kidney disease, bladder infection and urniary tract problems.
There are more studies about this product by OSHA and WHO stating that it is dangerous as it is a major component of polyurethanes, insulation, foams,
etc used in building materials, and one of the most widely used products in industry. There are MAJOR saftey procedures in place when dealing with
this chemical due to it's potential health hazards - enough to fill an entire 10,000 word posting. It also can cause psycho active effects similar to
PCP when smoked (which is what is happening with Vaping - but in lower amounts - which may be why people get a better "high" from vaping). It used to
be present in all kinds of plywood, particle board, MDF, press board (FEMA trailers that were condemned) all from off-gassing 10 years after
manufacturing when levels were about 1/2 of a percent of original off-gassing immediately after manufacture.
The carrier Propylene Glycol seems to be less of a health risk as it is heavily used in the pharmaceutical industry even in injectable drugs but can
cause upper respratory tract irritation (similar to pneumonia and bronchitis at same time) when vaporized and inhaled. Wiki states "According to a
2010 study by Karlstad University, the concentrations of PGEs (counted as the sum of propylene glycol and glycol ethers) in indoor air, particularly
bedroom air, has been linked to increased risk of developing numerous respiratory and immune disorders in children, including asthma, hay fever,
eczema, and allergies, with increased risk ranging from 50% to 180%" I was unable to find what the compound breaks down into when oxidized at high
temperatures and will return with answers when I find this.
It is ABSOLUTELY clear that all of the reports submitted to Congress have been created by the nicotine industry, just like they did 50+ years ago when
they said cigarettes did not cause cancer. There needs to be a MAJOR investigation into these products and methodology and those who popularize it
such as HOLLYWOOD need to be held accountable. Any company that allows for advertising of their products should be shunned/boycotted and people need
to write letters to them informing them of how dangerous these products are.
There is always a lag between the release of a product and the public becoming informed to the danger, and within this time period there are untold
profits reaped, and untold damaged inflicted upon the unsuspecting public. I suggest anyone who has any concern about these products to write their
congress person & senator and tell them they need to investigate this AS MUCH as they are into school security and gun issues. One is a
constitutional right while the other is a vice that has extremely negative health effects and I will guarantee the long term effect will be
sky-rocketing health care costs and insurance premiums due to people using these.
I propose that there be a ban on smoking these things in public or around children and it needs to be just as stringent as cigarette smoking. While
it may not have the 100's of chemicals of cigarettes (many of which are at levels so small they are basically negligible even over a decade of
use/smoking) the byproducts of vaping have been underestimated and hidden in order to allow their use and promotion in media and in public spaces,
including advertising to children (remember Joe camel cartoons - same story, just with the new angle - target children).
How do we get congress to look at this problem with seriousness?
