Serious question, are you the village idiot? Never mind, we know the answer.
You just posted a link to an abstract about a study that was conducted. You're
so stupid that you think that's "proof". It just says a study was done,
a little about the methodology and ABSOLUTELY NOTHING about the results. And you want to talk about my mental health and brains? If we didn't already know
you're the village idiot, that would go a long way to proving it.
I posted 4 links. Which one are you talking about? Care to discuss
what the article actually contained, or do you just enjoy being vague?
I already went through it with you. Once again, you're the village idiot.
Time to change your screen name again, to better troll, perhaps?
I like this article. Read the full article describing all the tech stuff
and results. IOW's, you'll ignore it because it proves you wrong.
"Formation of carcinogens indoors by surface-mediated reactions of
nicotine with nitrous acid, leading to potential third hand smoke hazards.
This study shows that residual nicotine from tobacco smoke sorbed
to indoor surfaces reacts with ambient nitrous acid (HONO) to
form carcinogenic tobacco-specific nitrosamines (TSNAs). Substan-
tial levels of TSNAs were measured on surfaces inside a smokers
vehicle. Laboratory experiments using cellulose as a model indoor
material yielded a10-fold increase of surface-bound TSNAs when
sorbed secondhand smoke was exposed to 60 ppbv HONO for 3 hours. In both
cases we identified
1-(N-methyl-N-nitrosamino)-1-(3-pyridinyl)-4-butanal, a TSNA absent in
freshly emitted tobaccosmoke, as the major product. The potent
carcinogens 4-(methy-lnitrosamino)-1-(3-pyridinyl)-1-butanone and
N-nitroso nornicotine were also detected. Time-course measurements
revealed fast TSNA formation, with up to 0.4% conversion of nicotine.
Given the rapid sorption and persistence of high levels of nicotine on
indoor surfaces€”including clothing and human skin€”this recently
identified process represents an unappreciated health hazard through
dermal exposure, dust inhalation, and ingestion. These findings raise
concerns about exposures to the tobacco smoke residue that has
been recently dubbed €śthirdhand smoke.€ť Our work highlights the
importance of reactions at indoor interfaces, particularly those
involving amines and NO x/HONO cycling, with potential health impacts."
