Ever seen what mercury can do?

Neat



Lobster -> RE: Most interesting video i ever saw... (3/5/2021 4:07:39 PM)

I have to wonder about someone who would play with a substance as toxic as mercury. Maybe they've done it too often already? [:D]

Well saw another video of him, said something he mined that mercury from cinnabar on rocks, etc. There a video he was talking about it and showed a mine in the ground and forge of some kind to draw the mercury from it. It was interesting.

Mercury is toxic in theory, but then so is lead, copper, and several of other metals. Mercury gets it's bad reputation because of the well known effects on hatters in the 17th century, but they were heating up their mercury and so generating mercury vapour which they then breathed in. You would also need a lot of surface contact over a very long time to ingest a significant amount through the skin.

The Evaporation Rate of Mercury at room temperature is so low that it can't be measured so there is no mercury vapour in the local atmosphere, which means that there is none to inhale. But nowadays Health and Safety legislation is so all embracing that it's not PC to give the situation some thought rather than taking the Material Safety Data Sheet information at it's most literal extreme.

Lead is very deadly even more so than mercury, it does not matter if it is jacketed with steel or copper, what matters is the feet per second . . . [sm=00000054.gif]



DeepBlack -> RE: Most interesting video i ever saw... (3/5/2021 8:59:45 PM)


Mercury was the main treatment for Syphilis before antibiotics
were introduced. It was rubbed onto the skin as an ointment.
Another treatment had the person locked into a sauna so mercury
vapors could be introduced via sweating pores.

Many Syphilis patients died from mercury poisoning. But, it was
a known risk. They knew it was really dangerous but it
was the only known way to treat the ulcers/lesions. The
treatments were given on a continual basis.

This led to the wry adage, "A night with Venus, a lifetime with Mercury".

Makes me wonder where he got all that mercury. I would think it's hard to come by due to it's toxicity.
In this form it does not absorb real fast into tissues but it's still dangerous. Heck many of the minerals in my mineral collection I handle with gloves!




Well he mention that his dad or grandfather knew where they were, i assumed they were miners from the pass. Plus he got connection to people that do alot of this stuffs.

Its very dangerous, mining coals, leads even golds. Get too much into your lungs, then you are fried and cant be fatal in some situations.

Here the video i mention, Where did i get my mercury?

The evaporation rate has a lot to do with how much surface area is exposed regardless of what the subject is. One square centimeter would take an exceptionally long time at room temperature (`70F). The surface area in the plastic tub in the demonstration is considerably more than one square centimeter.

And regardless of, 'don't do this at home', you know how rampant stupidity is in the world.[:D]

Even before the advent of Youtube people did stupid things. A friend and a friend of his decided they would make an explosive. I think gunpowder. They gathered the ingredients and while the friend of a friend was mixing some ingredients together they exploded in a pestle he was holding. So, the friend of a friend has the honor of only one hand and a badly scared neck, chest and arms. It almost killed him.

So I do have reason to take exception when a knowledgeable individual shows stupid people how to do dangerous things. [;)]

Mercury isn't difficult to come by if you have an account with a supplier, but it's expensive. I dread to think how much that lot cost.

When the evaporation rate is negligibly small then the total amount in the atmosphere remains essentially zero, however much mercury is there and however long it is present.

When they tore up the original wooden block floor in one of the labs I used to work in, they found quite a large pool of mercury underneath which had obviously dripped through the gaps between the blocks sometime in the past. I'm sure it wasn't spilled during my time there so it must have been there for many years. But as it doesn't evaporate at room temperature, no problem. I just cleaned it up for the worried building contractors. [:)]

If you are still worried about him breathing in any harmful vapor that might magically have escaped into the atmosphere, well he was working in the open air, not in a confined space.

But it DOES evaporate at room temperature. [:D]
One square centimeter would take somewhere in the neighborhood of 8200 hours to evaporate. That's a one square centimeter globule. At room temperature. That's about a year. It's prolonged exposure that becomes a problem. Being in a class where you spend maybe four hours maximum for a handful of days a week for a few months, even if you are the prof, wouldn't be a problem. If you lived there for years and there was mercury present the whole time then you might have health issues.

This is how it happens:

In 1989, several pounds of liquid mercury spilled in a child's bedroom. The mercury was not cleaned up sufficiently. He and his two sisters continued to be exposed to high levels of evaporating mercury for a prolonged period, and they suffered serious health consequences. (Source: CDC.gov)

Stupid people do stupid things. Someone will try to do this very same thing without any knowledge of what they are doing. You can take that to the bank. [;)]



RangerJoe -> RE: Most interesting video i ever saw... (3/6/2021 4:41:43 PM)

How about when people use mercury to dissolve gold then use a blow torch to vaporize the mercury then the gold remains? That is done in some mining operations.

How about when the recycling items are sent to another country without pollution controls or one where the controls are not enforced, then mercury and other chemicals are used in the recycling then the mercury and other chemicals get released into the environment?

Where did you come by the information to calculate the time it takes to evaporate? The Material Safety Data Sheet states that no information is available for the Evaporation Rate. (Section 9 - Physical and Chemical properties). That means that even Fisher Scientific couldn't make that calculation.

It's tragic about the kids of course, but you can't take a domestic bedroom situation where the kids may be playing with spilled mercury, even putting it in their mouths because their parents don't know the hazards involved, and compare it with a laboratory spill or a You Tube demonstration where the people involved have the professional knowledge to know how much respect they have to give chemicals without going over the top.



Narisomo -> RE: Most interesting video i ever saw... (3/6/2021 5:39:16 PM)

I didn't know that mercury has such a high density. Learned something useless. [:D]



RangerJoe -> RE: Most interesting video i ever saw... (3/6/2021 7:27:48 PM)

Mercury has a density over 13 times that of water. Think of drilling a hole in the center of bullet, putting a drop of mercury in it, then capping the hole with lead. That is in the book The Day of the Jackal.



Lobster -> RE: Most interesting video i ever saw... (3/6/2021 7:46:42 PM)

Mercury is one of the most studied pollutants on the planet because it is one of the most common and toxic pollutants. It's everywhere which is why there is so much information on it. If you eat seafood you eat mercury. Even a normal everyday household can have at least one source. Maybe more depending on barometers, thermometers, lighting and other devices. I suspect the evaporation rate in the piece I copied did not account for the diminishing size of the mercury glob as it evaporated. My brother in law bought a wooden crate of stuff from a liquidator and in that crate were several vials of mercury. At least three liters. Glass vials in a wooden case with each having it's own secure space. Imagine if any had broken? Don't know how he disposed of them. Probably sold them since he had connections everywhere.

It does take a long time to evaporate. That merely means it's somewhat like radiation I guess. [:D]

For me it's bothersome to see someone use it in such a cavalier fashion especially considering there is no control over the viewing audience.

This is from only one page after a simple search:

-----------------------------------------------------------------------

I found this statement in a paper about Hg contamination from dental work:

The evaporation rate of elemental mercury at room temperature (20 ∘C) is approximately 50 μgcm−2h−1 (range of 40−60 μgcm−2h−1).

They cited the following work as a source for that number:

Gary N. Bigham, Wanyu R. Chan, Manuel Dekermenjian, Ali Reza, "Indoor Concentrations of Hg Vapor Following Various Spill Scenarios," Environmental Forensics 2008, 9(2-3), 187-196 (https://doi.org/10.1080/15275920802121975)

German regulations (as an example) say that 0.035 µg/l of metallic mercury vapour in air pose no risk under lifelong exposition, and 0.35µg/l can be harmful under long (months?) exposition for some people. The math is full of imponderables, esp. the actual amount that was spilled and size of drops.

Swiss officials https://www.toxinfo.ch/quecksilberhaltige-fieberthermometer say that a single broken fever thermometer can lead to intoxications, but the risk can usually be averted by collecting as much as possible and ensuring proper, regular ventilation.

The following publication suggests that a properly cleaned up spill from a fever thermometer should become undetectable within several weeks, but the airborne Hg concentration can be significant in that time, and regular ventilation is highly recommendable.

E. Martin Caravati et al. Elemental mercury exposure: An evidence-based consensus guideline for out-of-hospital management, Clinical Toxicology 2008, 46:1, 1-21, https://doi.org/10.1080/15563650701664731

But one thing is quite clear: A single, large blob that you miss (under furniture, wooden floorboard etc.) can stay for a very long time, and lead to potentially harmful concentrations in the air. There are a lot of reports about little mercury puddles that were found under floorboards during laboratory renovations, even decades after the last mercury instrument had been thrown out.



RangerJoe -> RE: Most interesting video i ever saw... (3/6/2021 9:16:05 PM)

That was not liquid metal mercury, that is the compound that causes problems with eating too many high level predatory piscines.



stuart3 -> RE: Most interesting video i ever saw... (3/6/2021 10:43:15 PM)

A lot of this is not really relevant to the original topic. Compounds of mercury are not metalic mercury and some can be very much more toxic and some less toxic but you are unlikely to come across the really hazardous ones in everyday life. The same goes for other toxic metals.

If you are worried about how to deal with spilled mercury from a broken thermometer, which is as much as you are ever likely to have to deal with at home, then scoop it up using a teaspoon (push the small globes on using a knife if necessary) and put it into a screw top jar, preferably a plastic one. The vapour won't escape from that. Then dust the area of the spill with flowers of sulfur. I don't know if high street chemists still sell that, but Amazon certainly does. Leave it for at least 24 hours to convert any remaining mercury to mercuric sulphide which is safe. Then hoover up the powder and dispose of it in the normal way.



Rising-Sun -> RE: Most interesting video i ever saw... (3/7/2021 12:59:12 AM)

Curious if mercury can be use in the military, imagine using this idea make a ship or floating platform that is nearly undestructible, like a floating island that can move around on water. But still gotta find a way to keep all that mercury in the same place.
