uh oh..
As if we didn't have enough exposure to this toxic substance from our food containers, water bottles, CD-Rs, etc..
Is it just me or does the entire thing stink of "Big Chem" covering this up as long as possible, allowing it to build up to toxic levels.
Problem now is that this stuff is everywhere and nearly impossible to clean up.

Needless to say, using epoxy or many amine based glues could cause additional exposure and should be avoided.

Discuss.

It doesn't surprise me that even the MacTill receipts are MacToxic.

Must resist... making joke... about... BPA making alligator dicks smaller. (Apparently Bisphenol A causes that too, atleast according to some documentary, I forget).

Yeah, everything today is either made of or covered in poison. It's troubling, but not to the extent of me worrying over that bottle of water I drank. Or the receipt I got for it, either. If anything, I find this quite funny.

Oh crud, there's BPA in my keyboard too, gotta stop typing.

I think the "big chem" scare and just the plain old chemistry scare is bad enough allready.

It seems that you wanna make it appear as its some "big" "chem" company who manufactorers BPA fault that people use it in products where it is not suitable in respect to the health of the user of said products.

Maybe the company who makes the receipt paper rolls just figured out it'd be a tad cheaper to use the BPA instead of something else, maybe the water-bottle factory thought the same. Totally indepentenly, they decided to save some cash. The problem then is, if that really is what happen, the lack of control of those receipt/water-bottle/etc companys, not the BPA manufactoreres.

If there were a company who just checked things like this, the diffrent companies wouldnt get away with it and then find another (safer) chemical to use, possiably a more expensive one. Oh yeah and the company checking the products out before they are shipped to the users, would sort of have to be paid by taxes or something similar, which noone wants to pay. So you end up with higher taxes and possibly a more expensive product.

And by the way I got 3 tubes of epoxy laying around waiting to be used, and I sure am gonna use them all asuming I dont get run over by a drunk driver or gunned/knifed by a lunatic, point being, plently of things to get killed by before the BPA builds up..

What's the safe alternative to epoxy?

last time i checked there was a battle going on to get it removed from baby bottles due to the endocrine disruption issue.
seems that it is possible for people who use epoxy/etc daily to become sensitive to BPA, there was an article a while back on some medical journal.
Best bet is to wear gloves, and use it outside to allow the fumes to dissipate.

Interestingly many boat finishers use epoxy based glues by the gallon to bond glass fibre, and effects have been documented including headaches, nausea, chronic fatigue, etc but until recently it was believed to be the styrene fumes that were solely responsible.

Shock news!
No actual deaths attributed to BPA!

The epoxy part of an epoxy resin is much more likely to cause hypersensitivity reactions than the BPA.

Since BPA is a practically involatile solid it hardly makes sense to worry about "fumes" from it. On the other hand, styrene is known to give rise to headaches, nausea etc.
Oh, and since BPA will be metabolised reasonably quickly, there's no way that it can " build up to toxic levels." in the body.

I'm not saying the risk is zero; I'm saying that you need to look at both sides of the equation.
Without BPA we wouldn't have shatter-proof lexan plastics. I wonder if the number of people saved by this sort of thing exceeds the number possibly damaged by BPA.

It's also interesting to note that this endocrine disruptor

gets praised " Equol may have beneficial effects on the incidence of prostate cancer[4] and physiological changes after menopause.[5] Other benefits may be realized in treating male pattern baldness, acne, and other problems because it functions as a DHT blocker.[6] "
but BPA , being artificial is viewed only as a problem.

interesting. that said, epoxy in components is considered stable right? i wonder if heating up boards to remove parts generates epoxy fumes?

someone did mention that burning polycarbonate is known to be toxic, something to consider if you dispose of rubbish this way (like anyone still does this, right?)

If you took plastics , (especially chlorine chemistry types)out of the
mix of materials used to support very high density habitation, it would not work. These are the economics that drives the development. Cl2 is in the top ten products produced today.
If human settlements could live without electricity, the density would drop, and organic chemistry would return to the fire-pits and middens.

But PubMed lists 244 peer reviewed papers on the association between bisphenol A and cancer.

Much of epidemiology is probabilistic. For example, the association between smoking and lung cancer was denied for decades by tobacco companies
using the very kind of frivolous rebuttal you have used here. The same may be said of leukaemia clusters around nuclear power stations. In no
single case can radiation be proven to be the causal agent.
