Oxigen. Dont let them lie to you calling it natural death or that someone has died by its old age. The real cause is Oxigen.

Dimethyl mercury.

I thought it was sarin or something

smallest quantity?
fastest acting?

>Wetterhahn recalled that she had spilled several drops of dimethylmercury from the tip of the pipette onto her latex gloved hand. The exposure was later confirmed by hair testing, which showed a dramatic jump in mercury 17 days after exposure followed by a gradual decline. Tests later showed that dimethylmercury can rapidly permeate different kinds of latex gloves and enter the skin within about 15 seconds.[1][2]

>Five months after the exposure, it became evident that some initial serious neurological symptoms such as loss of balance and slurred speech were the result of a very serious debilitating mercury intoxication.[3][4][5] She was admitted to the hospital, where it was discovered that the single exposure to dimethylmercury had raised her blood mercury level to 4,000 micrograms per liter, or 80 times the toxic threshold. Her urinary mercury content had risen to 234 µg per liter; its normal range is from 1 to 5 and the toxic level is > 50 μg/L.[2]

>Despite aggressive chelation therapy, her condition rapidly deteriorated; three weeks after the first symptoms appeared, Wetterhan fell into a coma. One of her former students described it as not being "... the kind of coma I'd expected... She was thrashing about. Her husband saw tears rolling down her face. I asked if she was in pain. The doctors said it didn't appear that her brain could even register pain."[5] Wetterhahn died a few months later, less than a year after her initial exposure.

Nasty.

>most horrendous
that's not a meaningful descriptor

however, radioactive poisoning probably has a good mix of pain, death, potential disfigurement, no procreation (i.e. physical, mental, and social effects)

So what is it made of? Not chemicals?

>> No.5509868

Botulinum is the toxin created by the bacterium, idiot.

>> No.5509883

>>5509861
it's a protein that happens to be a neurotoxin

>> No.5509892

>>5509883
And amino-acids are made of...?

>> No.5509908

Osmium tetroxide is one of them (in terms of toxicity.)

Sarin, ricin, carbon monoxide, and cyanide rank up there as well.

Are we including proteins? They aren't technically molecules, just a chain of them.

It's super fucking dangerous.
Botox is injected into the skin though, not IV... unless you fuck it up.

>> No.5509940

>>5509922
even into skin, the dose in botox is microscopic

i mean literally microscopic. 1g of botulinum will make all the botox the world will need

Wow, that is nuts.

i actually got it wrong, that's mice of some shit

people is about 10 times that

still, you could kill everyone alive with a few grams

>> No.5509980

I'd say prions (mad cow etc) would be the deadliest, since it only takes one molecule in the right place to fuck things up.

it's not wholly wrong, there are structures we call proteins, where separate peptide chains have no chemical bond

Nickel carbonyl is pretty toxic, but I believe botulinum is the most deadly of all.
