Asbestos is really useful and also not really that dangerous to people who don't work in construction (or asbestos mining/manufacturing). Every day I go to work I'm around asbestos because it's good at it's job and not dangerous when properly contained and labeled.

Most people are surprised how many uses of asbestos remain legal:quote:The manufacture, importation, processing and distribution in commerce of these products, as well as some others not listed, are not banned.

GWBBQ posted:Send a chunk of drywall from any house or commercial building built in the last 10 years out for testing and I would bet that at least 1 in 5 come back positive for asbestos. Just because you can't use sheets of it for insulation or fireproofing anymore doesn't mean it's gone. How much, though? Is it enough to become bad? Like asbestos is just a silicate-based rock that happens to turn into fibers that love to imbed themselves into flesh. That then the body doesn't know what to do because silicate doesn't react with poo poo and can't be broken down.

Asbestos fibres are literally thin enough to interact with chromosomes in the cell and introduce mutations. They can be as thin as 250nm across.

Dynemicin and compounds containing the same enediyne structure (the bit with the triple/double bonds that's sticking out) are potential antitumour drugs. They basically slide into DNA molecules then rip them in half when the bonds cyclise, killing the cells.

Hell test most 12 inch tile and about 30 percent will come back positive. Granted the amount of asbestos is the tile is miniscule and you'd literally have to turn the tile to dust and scarface it to get any real kind of exposure but its still there.

That's a big part of chemical safety along with my other posts here about concentration.

Maitotoxin  Palytoxin Those're some of the most toxic chemicals known to man, produced by coral/plankton type things. Apparently, the second one was aerosolised in sea spray and poisoned 200 people in Italy a few years ago.

There are mg/m^3 limits that are applied to exposure in the workplace etc. but whether a single fibre can cause sufficient damage to trigger a mutation, I'm not the guy to ask about it. I'm just a geologist who likes cool chemical stuffs.

Yeah that's definitely enough to be concerned with if you're the one messing with the drywall day in and day out. Pretty sure it's impossible to do anything with drywall without getting dust all over. Sadly you're going to see a lot of that sort of thing. So long as it's low enough to round down to zero it's low enough to be considered zero. See also non-stick food spray (Pam) and their claim of zero calories.

That is still insane to me, and it means that once the fibers are in you, they're going to cause damage for the rest of your life, and it can't be stopped. I also didn't know that chemistry had symbols for substances like that, although it makes sense.

fade5 posted:I also didn't know that chemistry had symbols for substances like that, although it makes sense. The diagram doesn't specify it, at least not in the sense of any of the symbols used there meaning "this is hazardous" or anything like that. The part of that dynemicin model above that's sort of jutting out weirdly is a ring of carbon molecules coming out of the plane the rest of the molecule is drawn in; the solid wedges indicate a bond pointing "toward" you, and the dashed wedges indicate a bond pointing "away" from you, from the perspective the molecule is drawn in. The long double or triple lines indicate, appropriately enough, double and triple bonds. Edit: this was the model I was referring to:

I think it's one of those toxins animals get from bacteria/their diet rather than synthesising themselves, like poison dart frog's poison. That might explain it being in a bunch of different animals. Batrachotoxin, a toxic alkaloid found in poison dart frogs.

GWBBQ posted:0.1-0.5% or so, enough to be a concern if you work with it but less than the 1% that gets it legally defined as Asbestos-Containing Material. If what you are working with drywall that contains that much asbestos and it has been tested for and come back positive as asbestos containing material you should be attempting to wet it and have some sort of vacuum suction applied while you're drilling/cutting. A good quality dust particle respirator always helps too.

Tunicate posted:Thomas Midgley Jr, yeah. Known as the man who had the single greatest impact upon Earth's environment. I know this is a little late, but I thought I'd point this out: "On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of TEL. In this demonstration, he poured TEL over his hands, then placed a bottle of the chemical under his nose and inhaled its vapor for sixty seconds, declaring that he could do this every day without succumbing to any problems whatsoever" Shockingly enough, "Midgley sought treatment for lead poisoning in Europe a few months after his demonstration at the press conference." Dude had a truly uncanny sense for bad ideas.

Platystemon posted:It’s capitalised, so we know that it doesn’t contain a certain planet or Roman god, but the element is still a possibility. More like a certainty! Mercury is hardly a super rare element, and while uncommon it's still ubiquitous in the environment in small amounts. In the soil in which crops are growing, in the crops themselves, in the chicken who are fed the grain. Not enough to cause a problem (probably), but it's inevitable there will be atoms of mercury in every food. As for mercury in soil, I remember hearing about areas of Mexico where the soil is so thick with mercury you can pick up a handful and squeeze it, and mercury drips out. Mine tailings from gold mining over hundreds of years. (I probably read about it in this thread!) Considering the lax environmental policies of the United States (and, honestly, almost every country in the world), there will be plenty of foods with decent amounts of mercury in them. Again, it probably won't be enough to cause your brain to melt, don't stop eating just because you're worried about mercury, malnutrition makes your brain melt even faster.
