    Speaking about the gas mask I once did a university placement studying Radon; and again it was found that activated charcoal made from coconut shell is the most efficient absorbent. Even more so when cooled by liquid nitrogen. A cryogenically cooled-gas-mask may function even more effectively than a standard one. Interesting stuff.

    • @goat9385
      @goat9385 8 років тому

      I would suppose that the reason it is more effective is because of thermal shrinking within the fine ground coconut carbon making the gaps between the carbon molecules even smaller.

    ***** I know this is a bit of an old video to be commenting on. But this was a great visual for me. We learned a lot of this chemistry during one of my paramedic classes. Mark I and Mark II kits used for field treatment of nerve agents, or organophosphate poisoning also included Atropine. We no longer carry Pralidoxime and our protocols change to an Atropine only treatment. Could you explain the chemistry behind how Atropine alone works to counteract nerve agents or how the combination of the two work together. I'd also love to see more videos about the chemistry behind more of the medications I use in the field. The way you format videos gives a visual and I feel helps immensely.

    • @BewilderedBird
      @BewilderedBird 6 років тому +5

      Miles McDonnell The end result of acetylcholinesterase inhibition is an excess of acetylcholine within the synapse. To counteract this, anticholinergic drugs lie atropine are used and it works by blocking the receptors that acetylcholine binds to. So while it doesn’t directly decrease the amount of actylcholine , it will lessen the negative effects by blocking its binding.

    I once heard that the antidote for a nerve agent ( I can't recall if it was sarin or VX ) was lethal if the user had not actually been exposed. Is this true? I started wondering about this when the explanation for the chemical interaction of the sarin antidote was given.

    • @DarkFire515
      @DarkFire515 8 років тому +17

      +Josh Bonds Partially true. Atropine - the common antidote to nerve agents (e.g. VX) - can be toxic if the dose is high enough. The auto-injectors issued to NATO troops is said to contain enough Atropine to cause an adverse reaction if the patient hasn't in fact been exposed to a nerve agent.

    Its main purpose is supposed to be smoke screening if I remember correctly. If you need a smoke screen now if not sooner a WP grenade will do that. Which is why tanks have white phosphorus launchers on them, so they can instantly have a means of hiding. I wasn't aware that it was flatly banned for use against combatants; I thought as an incendiary weapon it was only banned for aggressive use when civilians are nearby. (per the Geneva Convention on Certain Conventional Weapons).

    12:30 Indeed, considering that you combat troops ARE equipped and protected I would say that it is civilians, rather than solders, who are the INTENDED targets of chemical weapons. This is most likely why they were not used in WWII and their use, even in modern warfare is so limited.
    Now I can see the use of such weapons as a detraction, if the enemy troops are busy caring for civilian casualties they can't attack you. I think it's clear they are meany to harm civilians more than troops.

    It depends on the dosage of the gas, in a confined space nerve agents can kill within minutes if that, however you're correct that getting a small lethal dose in a ventilated area would lead to a very long drawn out death which I assume would be agonizing
    Nerve gas really is a terror weapon much like nuclear weapons and biological weapons, it's more effective against civilians than soldiers and works best in concentrated urban areas.

    All modern warfare is horrendous. Say what you want about Saddam Husseins evil in Iraq, but in the course of the most recent Iraq war, about a quarter of a million people died, and the few of them were soldiers, and that was a war waged by one of the most advanced militaries of the world, the US.
    There's one United Nations institution we are desperately lacking, and that is one that specializes in counselling warring parties to tame the effects of armed conflicts, and providing publicly accessible military research for how to avoid civilian deaths in military confrontations.
    We need a United Nations Institute for Civilian Safety.

    One little nitpick at 5:29. Without AChE your muscles stay in contraction I believe. Thus your arms and legs would always stay in flexion (foetal position) and your lungs would stay in inhalation (diaphragm contracted breathing in) and you couldn’t exhale. Hence convulsions. It is worse medically because you can’t do artificial respirations as well (without suction). Sorry if I’m wrong but I believe lack of acetylcholine would cause the described action (Botox). But closer at 8:35 in the description of the inability to hydrolyze. The other thing that happens is the immediate overproduction of fluid (saliva and watery sputum) so the lungs fill with fluid and gas exchange becomes impossible - and again, artificial resps don’t help.

      Not really, sure if you pluck out the sentence "luckily there was no chemical warfare what-so-ever in the second world war" that's incorrect. But given the context of him talking about "the allies" and "the Nazis" and how he's specifically talking about the development of chemical weapons by those powers, his statement was correct, as neither of those sides used chemical warfare what-so-ever in the second world war. Now, you are right about the japanese using chemical chemical weapons during ww2, but he wasn't talking about them.

    It isn't pointless, you just have to stay calm and keep to the point.
    If they insult you, ignore it. If they say something that is wrong, don't insult them, tell them why they're wrong.
    It's that simple. I've had many debates/conversations that have started ugly but ended happily simply because I stayed respectful towards the other person even if they insulted me.

    Not many UA-cam channels are cross-cutting in the professional manner that this channel is.
    Every unresolved cutaway makes me lean in more lol like its lord of the rings or something 😂
    The soundtrack is chosen well and perfectly mixed too. The only audio issue is the inconsistent dialogue levels. Only in some videos, not all. Could just be the on-site mixing, no much you can do if it isn't proper. The rest is seamless.
    Y'all got a real editor on your hands. Fantastic work. Are there film/television post-production students working on these?

    Pralidoxime is but one treatment, and its use is limited to admin within a certain time frame, depending on the cholinesterase inhibitor. Past a certain point, "ageing" occurs where the irreversible binding of ACheI to cholinesterase is too much, and only supportive treatment is sufficient. Atropine is used instead and is the first line treatment in emergencies until access to pralidoxime is available; because as an anticholinergic it can compete with ACh and reduce the excessive signalling.

    “Now that’s vinegar now” I liked that illustration. So many Americans don’t understand the way that chemistry actually changes the identity of substances, they mistake it for something like a cake recipe where the inputs remain.
    Though in the animation not sure why they didn’t just depict the sarin molecule as a Pie wedge filling acetylcholine pac-man’s mouth.

    I really like Rob Stockman. He explains things so simply and yet with great clarity. Those models are great to see too and he seems to know a lot about human biological/chemical processes and molecules. What is his specialisation?
    I'm also curious - It's obvious why it's illegal to produce, but is there any non-toxic use for this Sarin molecule? Are there any legal applications for it? Is it ever allowed for research? It seems odd that there would only be self-destructive uses.
    Thanks guys. :)

    The fluorine is considered a "leaving group". It leaves the sarin molecule so that spot can bind tightly to the active site on the cholinesterase molecule. I'm not sure what happens to it, it probably rebinds to a nearby hydrogen atom in a water molecule and makes HF. That bond is pretty strong, which is why HF is a weak acid (see recent Mythbusters episode).
    BTW, it doesn't have to be fluorine, it can be a pseudohalogen like CN- as in tabun.

    Forgive my chemistry errors beforehand:
    If you drank flouridated water like we have in the U.S. Would traces of that show up in a hair sample?
    Would it show up as the same element in the hair sample of a sarin gas victim? If the same, would the concentrations found allow one to conclude one way or another whether the source was flouridated water or sarin?

    Have you read the relevant law? As an incendiary, WP is banned for use in civilian areas or on civilians, but incendiaries ARE allowed for use on combatants in the field of battle. There is no regulation against large bullets (although the Hague Convention bans expanding or exploding bullets under 400g weight). WP's main use is as a smoke screen, not as an incendiary, however. There are much deadlier incendiaries out there.

    Not much details in public-domain but I did ask someone who works in a government chemical-weapons laboratory (they test gas masks and how to detect gas attacks like we've seen in Syria) and he confirmed being exposed to Nerve Agents like Sarin is LITERALLY the most painful thing as all your pain receptors are jammed "on" you literally feel the worst of every sort of pain, burning, freezing, tearing.
    And your suffocating, paralysed by seizures and totally blind.

  • @ApolloWasReal
    @ApolloWasReal 11 років тому

    I just think it's interesting to see how the route makes such an enormous difference in toxicity. Most of that seems as expected, e.g., the volatiles like sarin are most hazardous in inhalation while vx is hazardous on contact. Botulinum is fortunately a huge molecule that doesn't come through the skin, but if it does get inside a very little can cause a lot of damage.
    And plutonium seems nowhere near the top of the list...

    I'm having trouble finding updated articles, so thanks for the information. That's the Blue Grass Army Depot in Kentucky? What about the Pueblo Chemical Depot on Colorado? The destruction deadline was in 2012, wasn't it?
    They seem to have a good safety record destroying this stuff at other US sites so it's not like there are still a lot of unknowns left. At least it *can* be destroyed just with chemistry, unlike heavy metals and radwaste.
