When I was young my Dad bought me some mercury home from work.. I loved how it moved when I shook the bottle and the weight of it.
When I had my own kids I didn’t want it around, so our local council had set up a event where you could dispose of household liquids like old paints and solvents, so I took it down. When I drove up, the guy asked me what I was disposing of so I said mercury. It was bizarre. I was told to stay in the car and a guy came out of a shed in a full hazmat suit with one of those pairs of metal tongs to retrieve it from me.
I remember Dad telling me that miners used to collect gold pan tailings in mercury and then of a night they would hollow out a potato and put the mercury in, and then put that in the camp fire.. it would burn off the mercury and leave a little ingot of gold.
Probably because they didn't know WHICH type of mercury you had. Organic mercury can kill on touch with a single drop. Best not to take chances.
I had to search for "organic mercury", it's dimethylmercury and it doesn't look like mercury at all. Do people really call it "mercury" or "organic mercury"? It's on par with pounds as a measure of mass, weight, and force by the amount of confusion, I'd say 🤔
::: spoiler sad story
that was in the top of search results about dimethylmercury:
sad but also a bit ironic fate 🫡 that's why I prefer not to do dangerous things even when protection and/or safety is in place.

No, I doubt it. There aren't very many uses for dimethylmercury due to its potential lethality. I would assume the people who actually use it in a lab setting are going to call it dimethylmercury, especially considering organic mercury usually refers to methylmercury, or one of the other less harmful organomercury compounds.
I think the confusion probably stems from the original article about the scientist who passed. Dimethylmercury is made from a reaction of methylmercury, and they are both organomercuric compounds.
I think chubbyemu did a video about this lady. Absolutely tragic and heart breaking.
Source? I'm not sure who to believe. People on the internet who claim it's safe enough that you can pick it up or people on the internet who claim kills you if you touch it.
I'm not going to go swimming in a mercury pool any time soon either way.
Chemist (and biochemist) here. Organometallic compounds of Mercury are primarily dangerous because Mercury ions bond fairly strongly to soft ligands like sulfhydryl groups found near the active sites of enzymes. This can result in the displacement of the metal ions or otherwise disrupt the structure needed for enzyme functionality. Mercury metal OTOH is considerably less reactive. It is not safe to breathe in for prolonged periods of time but it is no where near as toxic as its organometallic derivatives are. Dimethyl Mercury for example, is extremely dangerous. A single drop has 100+ times the organomercury content needed to kill someone.
I think they are saying it depends what you mean by "mercury" because some compounds are both toxic and readily absorbed through the skin.
Exactly that. Elemental mercury (ie: the liquid metal form) doesn't readily absorb through the skin. It gives off vapors which are harmful with extended or repeated contact, but generally it's not super dangerous to be around.(Not totally safe though)
Organic mercury compounds (eg: methylmercury) are extremely toxic because they can be absorbed through the skin, and can traverse the blood brain barrier
Regular liquid mercury is relatively safe to handle, but I would still wear gloves. It won't get through undamaged skin, but is dangerous if you have even a small skin laceration it can get through.
you can always consult the Material Safety Data Sheet
For comparison, dimethyl mercury
Elemental mercury is not going to kill you if you touch it- wash hands and call a doctor. they'll probably be like, "Take two asprin and call me int he morning so I can bill you twice." you definitely don't want to inhale it, but outside of something like a fire or being heated, adequate ventilation is sufficient; if ventilation isn't possible a respirator is a good idea. Dimethyl on the other hand... is nasty.
Out in the edge of the lower mainland of BC by Hope, where there was a mini gold rush a long time ago you can find lots and lots of mercury sitting below the water levels when the streams dry out during the summer.
It is all left behind from the miners back in the day.
Mercury sitting below the ground level sitting underground, potentially poisoning the ground water if it gets disturbed enough is beautiful or just the area of nature where the gold panning happens?
It's a shitty situation, but that doesn't preclude it from possibly being beautiful to look at.
Its also harmless, generally, when ingested as the gastrointestinal absorption of elemental mercury is negligible. It is inhalation that is most concerning with elemental mercury.
Except eating paint chips with lead made a lot of kids dumb. Lead based paint held up awesome, but it was banned due to injection. Not inhalation. Even now, 40+ years later it's still the leading cause of lead poisoning in children.

We also had an innocent looking little (maybe 100ml or 200) bottle of mercury at school. Mostly for the startling weight when it was passed around to demonstrate density.
Nine out of ten hatters recommend that you don't do this. The tenth hatter purple monkey dishwasher.
(Victorian-era hat makers were notorious for going mad because they used mercury to treat felt cloth.)
I wondered what the Mercury actually did with the felt, as I couldn't think of anything from the top of my hat:
Mercury made the felting process in hat production more efficient. The compound used to moisten the fibers was Mercury Nitrate, a process known as carroting. It produced a superior-quality felt, which in turn, resulted in higher-quality hats
Mercury Nitrate
Which, should be noted, is not the mercury show in the picture. Mercuric nitrates are a white/yellow dry powder that is the result of mixing mercury with nitric acid. The process of making mercuric nitrates, and carroting itself, both result in rather toxic fumes that you really should not breathe in.
Handling liquid mercury is basically almost harmless as it absorbs through the skin really slowly and doesn't produce much vapours. Putting it in acid, heating it up, and putting the cloth treated with it in an oven is not.
Could have been. I know Lewis Carroll liked to lampoon issues of the day in his writing.
I think the original idiom was "mad as a hatter" which was eventually shortened to "mad hatter", possibly due to the Alice in Wonderland character.
I wonder what secondary compounds this was creating. Elemental mercury is pretty much fine, but if it was reacting with other things to create wacky fun times...
they chewed the leather to hides to soften them, IIRC. so it wasn't just getting on their hands, they were ingesting it.
It's so much harder believing in six impossible things before breakfast when you're allergic to quicksilver.
If anyone else was reminded of that video of a 110lb anvil floating in a tub of mercury, here you go. Don't try this at home.
didn't they use to use shitloads of mercury for floating the lenses on a lighthouse, letting it turn without too much in the way of friction?
Anyone who’s studied high school physics will also remember one of the biggest blunders of modern experimental physics: the Michelson-Morley Experiment which infamously attempted to prove the existence of the aether but rather gave them a pretty clear confirmation of a lack of the aether. It actually ended up helping form one of the basic tenets of Einstein’s Special Relativity, which is that the speed of light is constant within an inertial frame of reference.
They floated their interferometer setup on a sandstone slab measuring 1.5m x 1.5m x 0.3m in a giant circular trough of mercury in order to provide near-zero friction and reduce vibrations.

Not only is this technique still used to insulate large optical devices such as telescopes but liquid mercury is even spun around to create mirrors for telescopes: https://en.m.wikipedia.org/wiki/Liquid-mirror_telescope

Metallic murcury can't actually be absorbed through the skin, and it can theoretically be handled without protective equipment if you know what you're doing. Not that I would recommend it.
See the crazy stuff that Cody's Lab does on YouTube, and he hasn't gotten poisoned yet:
Mercury poisoning isn't all or nothing. I love love love Cody but also that boy probably has a little mercury poisoning at this point ngl.
My friends Dad showed us one time handling it in his hands, he said you just have to be absolutely certain you have no cuts or injuries that would let it get to your bloodstream. That was a long time ago now, today's parents would probably freak.
He's back and posting fairly regularly again, and better news is that he finally got paid by Google!

Mercury can absorb through the skin, but it takes a very long time. (Generally safe to touch it, but still wouldn't recommend it)
You could just.... not inhale liquids you're holding in your hands. Probably a good idea even when it's not mercury
/s
Nah, it's the vapor that's dangerous with elemental mercury. Touching it is basically fine. Just no open wounds and be in a well ventilated area
There are far more toxic forms of mercury you shouldn't mess with though
Is it more the inhalation than the skin absorption that would be toxic? Not too familar with mercury poisoning.
I've played with mercury when I was a kid. Hopefully it doesn't come back to bite me in the ass when I'm old.
Both my parents have told me playing with mercury like this was pretty common when they were kids. One's still alive. 🤷🏻♂️
My aunt even drank some and nothing happened.
Metallic mercury should be fine. Not the fumes though.
It was commonly used as medicine for quite some time.
It didn't work, but then nothing much did at the time.
Dads old mercury filled carburetor sinch worked much better than the oil filled one ever did.
