A Scientist Spilled 2 Drops Organic Mercury On Her Hand. This Is What Happened To Her Brain.

[@manolisgledsodakis873]

*NOTE:* This video is about *DIMETHYL MERCURY LIQUID* and *not* mercury metal. Comments about mercury metal are as irrelevant as comments about *mustard* would be to a video about "mustard gas"!

[@luckyalert5614]

This is very true. Can everyone please stop commenting about how "but they played with mercury in school and nothing happened". There is a massive difference. Also since my comment has caused so much confusion, dimethyl Mercury is an atom of elemental mercury joined to a dimethyl group (2 carbons and 6 hydrogens) meaning that it has significantly different priorities. Kinda like how hydrogen is a flammable gas, but attach 2 hydrogen atoms to an oxygen and you've got regular old water.

[@FelipeKana1]

WOW thanks for this. I was kinda worried because I'd seen this video a long time ago and yesterday at my class a student broke his mercury thermometer and I got really worried

[@OlOleander]

Her name was Karen Wetterhahn, and she was an extraordinary chemist. She worked at Dartmouth College, where she established the Women in Science Project, doubling the percentage of women pursuing science degrees. She was exposed to a lethal dose of dimethylmercury in 1996, and less than a year later, in 1997, the scientific world lost one of its brightest and most inquisitive minds. Her legacy lives on in both her efforts to involve more people, especially women, in the sciences, and her colleagues' efforts after her death to increase workplace safety and the regulation of harmful chemicals. Karen Wetterhahn: Oct 16, 1948 - Jun 8, 1997.

Due to bioethical reasons, you should not reveal the name of the patient. That is exactly why the presenter used her initials only to identify her. Those in the medical field will know that one should only be identified by their initials in presentations for privacy and confidentiality. Edit your comment and remove the name please. You can pay homage to her by other means but certainly not here.

@@hedayatsm553 Hi. I'm *in* the medical field, and have been for some time. Not only is the Wetterhahn case widely known and distributed in medical and safety literature, she's right there in the description. Perhaps condescend about bioethics to somebody else. I'm well aware of HIPAA, and have been since before my days treating patients in the Navy. Using initials is standard, but Wetterhahn's story outside her diagnosis and treatment are just as valuable to industrial hygiene and science education as her treatment was to medicine. Thank you, and have a lovely day.

This is a well-known story to us chemists. She's a hero too. Essentially okayed every form of experimental medicine and procedure that was known at the time, called medical teams super early in advance knowing she was basically going to die once it was found out that the glove type used was actually NOT good for the chemical used (contrary to what was understood at the time). A lot about mercury poisoning was learned from this case to be applied to future medical cases.

This is the first time I say it in public. I am a medical student myself and this happened to me in my first year of studying. 3 years ago I was exposed to mercury intoxication which was present in fish. I felt very bad after eating the meal and immediately after 20 minutes my body reacted by vomiting all that bad food. I did not even really think it could have been an intoxication. Without any thoughts I went to sleep and nothing happened in the next days. Exactly one week later I started to have really strange discomfort in my abdominal region such as pain and cramps. I left the lecture and went home. On my way home I experienced disorientation and difficulties in my balance or motoral functions. That day I couldn't move out of my couch. I was laying there straight with only being able to move my eyes for three hours. After this my most horrific time in my life started. I called ambulances every evening straight for 4 days. The doctors could not find anything in my blood, urine, organs, x-rays, CT's, MRI's and ultrasound. Pain started in my chest, which made no sense, because there can't be any type of pain in the areas and it was not caused by any organs or muscles. Finally, after very precise examination and diagnostic tests, my doctor was able to diagnose an intoxication with fish product which was mercury. He told me that he had already a patient with the same symptoms and it took him up to three years to get back to "normal" life and health. Exactly as he told, I gained slowly my health back over three years. During this time I had extreme pain and discomfort in my whole body, fatigue, decrease of concentration and the ability to memorize things and loss of weight due to loss of appetite. All this together also created a type of depression. For you guys, I really want to remind you to pay high attention to every food and product you buy. Always check for the date of production or preparation! I don't wish anyone to experience such a horrific time in their life. I can't even imagine how Karen Wetterhahn must have felt after her intoxication. Rest in peace.

[@xijinping4418]

What you went through sounds horrible, and I'm glad you made it through it. I don't think it's fair to say that you went through the same thing as KW though, what you were exposed to was not dimethylmercury. If it was, you almost certainly wouldn't still be with us today. Hope med school is going well for you though! Best of luck, from a random stranger on the internet.

@@ClaudiaM-f1y mercury comes up through the food chain in the ocean. The larger predatory fish like albacore tuna accumulate mercury in their flesh. If you eat enough, like me, your body will be unable to detoxify quickly enough and mercury gets into your cells. Conventional medicine doesn’t recognize you can get poisoned by eating too much fish. So there would be no use to pursue legal action as I couldn’t back it up with much medical research. It was also my ignorance to eat so much of their product.

I had a science teacher in my secondary school (located in a city in southwest England called Bristol). Amazing guy, Very, very smart and always adding to our learning by supplementing other general science facts which I and many others even minutely interested in the subject found utterly fascinating all the time. He told us this story about him as a young child getting a temprature reading, most of the thermometers at the time contained Mercury, this is probably sometime in the 60s/early 70s as he was in his late 50s teaching us in 2015. But he bit the thermometer too hard causing it to break releasing a few grams of pure mercury into his mouth, he was expected to pass away by most estimates or survive with severe neurological decline. Luckily he survived and amazingly even with that certain neurological decline he got a Degree in chemistry and became a teacher. Still one of my favourite teachers and I really hope he's doing well as I don't remember seeing him again after 2018. Thanks for reading, Rest in Peace KW

[@Sashazur]

In high school chem class someone asked the teacher what would happen if you ate a little mercury metal. He said it would come out the other end fast enough that it probably wouldn’t do much if any damage. He wasn’t a doctor so I’m not sure how correct he was, but considering the many decades we used mercury thermometers with kids, I doubt it was a death sentence. UPDATE: After googling a bit it seems my teacher was right. Of course you shouldn’t intentionally eat mercury, but a one time accidental exposure like swallowing a drop from a broken thermometer is unlikely to be harmful.

[@candicezinnick3449]

The most toxic aspect of metallic mercury is that it it can easily evaporate, and then be inhaled/breathed in.

metalic mercury is a lot less dangerous than organic compounds of it. Due to how comparatively badly its absorbed. Still toxic though.

And this is why you report all chemical spills and exposures to your lab manager, no matter how small or insignificant you think it is. I should make this mandatory watching for my lab.

That wouldn't work, since it would acclimate the lab manger to the idea that most reported to him/her are harmless, and may result in spills receiving less attention than they should. Unfortunately there is no solution here that is more simple than making sure all lab employees understand and regularly review the relevant chemistry and safety procedures.

Referring to iron monkey, I don't know if there would have been hope for rescue after the exposure, but the chances are better the sooner you treat it.

That doctor of chemistry was so accomplished and gave her life in pursuit of research. Terrible loss. When I worked in labs, way back in the 1980’s, a problem we had was finding gloves and other safety equipment which fit. The women omen wore XS or S, but very few were ordered in those sizes. We would request more of those and fewer Large and XLarge. The reply was that each lab was stocked with what the majority of employees used. The empty box of small gloves can lead to a snap decision to use a different type of glove. Each type of material has different properties. Some might absorb liquids you’re using and others would protect you. In my case, large gloves worn to protect up to the elbow were so loose, the liquid I needed to avoid splashed inside the opening and ran down my arm. I was working with HF acid solution. Luckily, I was barely injured, but I was rushed to the hospital just in case. (my boss also threw a bucket of dilute base on me, to help and surprise me) Glove protection was just part of the problem, but there were many problems regarding what was considered average size. I hope now that the women in the lab now can have more influence over lab design, equipment layout, and accessory sizes. We were advanced enough to start earning more science degrees, but still had much to prove to gain respect. Safety can make all the difference. The situation in the video really brings back so much.

[@ChevisPreston]

For those who are unaware - Karen was a(the) leading, and to this day, quite possibly the most, mercury compound researcher. This not only included mercury, but salts, organic and inorganic compounds as well. At that time we knew that organic mercury was extraordinarily dangerous - mostly thanks to her. People already wouldn’t work with the stuff, but she refused to let her findings deter her. We knew there were compounds like this, but because of her the entire lab safety and material awareness protocol changed. There’s only been a handful of deaths like this since - I entirely contribute that to her. Even as she was approaching death, she used the experience to allow others to learn from. I’ve worked with organic mercury and DMM. I would feel safer working with a hydrogen bomb. We would suit up and even then, only feel comfortable in a fume hood, with tongs, multiple layers of protection, specialized equipment, and a well in advance planned disposal. If it wasn’t for her, no doubt many many more would have died. Only her extreme expertise and focus could have been able to determine the cause - thank you Karen.

"At that time we knew that organic mercury was extraordinarily dangerous" It was known for decades before her. Organic compounds are generally more dangerous than inorganic.

He also told it's highly flammable and not to play with it. By this time i had already kept it aside in spatula and it spilled on my hand. I washed my hads immediately and my skin became pale. I showed to the chemistry teacher and told the phenolic compound fell on my hand, he scolded and opened a jar with a base chemical that can absorb the acidic compound that fell on my hand. He took the powder and held my hand inside that. After sometime he removed and told me to go take rest and observe if anything happens. I kept observing my fingers and i saw a burned dot forming on tip of my finger. He didn't put the base powder on my finger tips. Since it was just small burn the size of a mole i ignored it and everything went back to normal. If the chemistry teacher didn't act on time, i would have been handicapped.

This is a different compound is it not?

[@omelette4604]

this video is about a different compound. the symptoms aren’t even that similar to what hatters experienced; this chemical can basically cause dyspraxia - grossly impacting motor skills - as well as interrupting brain perception. the kind of mercury hatters were exposed to caused behavioural problems, it was much more psychological and the physical symptoms were painful but not extreme like the ones shown in this video (headaches, shaking. things you can really live with, as horrible as they must’ve been. jagged handwriting is a symptom but it usually comes in much later than this woman experienced, with prolonged exposure without any form of protection.)

I remember finding a pint sized bottle (completely full) of mercury in an abandoned paper factory when I was 13yrs old. I'll never forget how astonishingly heavy it was for the size. My friends and I thought it was coolest thing ever... We were pouring it in our hands, throwing it at each other, some of it even went the river... I don't remember what happened to that bottle. But I recall finding tiny beads of it in my bedroom carpet for VERY, very long time... This was almost 30 yrs ago, I sometimes wonder if I'll eventually pay the price for this... Then again, maybe I already am.

[@andrewmandrona7891]

A history tidbit for the few seeing this comment: Decades ago, NASA was trying to get higher thrust out of rocket engines, and this time they were looking for propellants with higher density than the usual kerosene or hydrazene. Dimethal Mercury is one of the densest combustible molecules, so they ordered several tons of the substance featured in this video for testing. Earlier, the lab producing Dimethal Mercury had this _exact same thing_ happen to one of their scientists, the one you mentioned. Understandably, they declined to provide the substance, and made sure that the engineers received a very, very detailed lecture on Mercury toxicity.

[@bmobmo6438]

Hmm, yes, let's burn an incredibly toxic organic mercury compound as rocket fuel, i'm sure this won't be the worst ecological decision humanity has ever made

[@eliz_scubavn]

Similar happened with chlorine trifluoride. Basically this chemical burns ridiculously easily, and the Nazis wanted to use it for flamethrowers and bombs. They made 30 tons of the stuff before realizing that it was far too dangerous. Aside from being required to store the chemical in specially fluorine treated metal tanks which stopped it from burning the metal, ClF3 was basically capable of burning anything on contact including concrete, asbestos and metal. In one later incident the chemical burned through 3 feet of concrete floor and then through gravel, spewing out hydrofluoric acid in the process which burned everything it touched. Fires set by using it can’t be extinguished with water or other materials either, which generally make it worse. Luckily for everyone it never saw combat use and was banned in international law.

[@davydiver]

Was this propellant called by the Russians Devils Venom?

[@andrewmandrona7891]

@@davydiver No. That was a combination of UDMH and nitric acid. Nitric acid is extremely corrosive to most metals (and humans). UDMH, or Unsymmetrical DiMethylHydrazine, is for once exactly as bad as it sounds. It's extremely reactive with many substances, and is both highly toxic and carcinogenic to humans. Nitric acid rockets have long since been replaced, but UDMH (and its cousins MMH and plain-old hydrazine) along with Nitrogen Tetroxide are still used as propellants because there really isn't anything to fill their niche. Fortunately, their combustion products are fairly safe, and they aren't toxic enough to kill with such little exposure.

There's no such thing as "better gloves," because with all the variety of chemicals out there, you'd make a glove that's impervious to one type of chemical but susceptible to another.
