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

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.

And currency!

I think chubbyemu did a video about this lady. Absolutely tragic and heart breaking.

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.

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.

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?

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.
