15 Deadliest Toxins Known to ManJun 06, 2021
Oh fish, let's make one thing very clear, there is no shortage of things on this earth that can kill humans with relative ease, there are deadly substances in microscopic amounts and they can come from unexpected places or creatures, some are even present in almost every parts number 15 strychnine this alkaloid is twice as deadly as sodium cyanide and has an ld50 of 2 to 6 milligrams for unfortunate laboratory mice, which equates to an ld50 of around 100 milligrams for humans consuming strychnine can cause death by suffocation in as little as 30 minutes as the muscles of the body involuntarily clench strychnos nux-vomica is the tree that produces strychnine and is native to southern Asia and everything associated with the tree, from the bark to the leaves seeds, it is quite poisonous.
I would like to imagine that the strychnos nux-vomica is the tree that would be found in the sequel to the giving tree which follows our hero Nux vomica avenging his friend the giving tree from the first book by calling that selfish Doge of an old man who killed the tree that da and said hello i was best friends with a given tree take these orange fruits even though it revitalizes you completely to keep taking advantage of other talking trees and then the old man eats the fruit and dies because it is a tree fruit of strychnine not bad with strychnine trees folks ain't nobody number 14 aflatoxin b1 the ld50 of aflatoxin is 2 to 3 milligrams per kilogram which means it takes about 100 milligrams to kill most adult humans but it does exist a second danger when it comes to this toxin as it is also possibly the most potent carcinogen
knownthis sounds like a toxin straight out of science fiction but actually it comes in the form of a certain species of fungus that is usually found growing decaying. legumes like peanuts so if you come across a yellow green moldy peanut don't touch it eat it it can actually give you acute hepatitis and it will destroy your liver or make sure you gi get cancer even though the fact sheet Material Safety is littered with the word cancer and fatal when describing this poisonous crystal so avoid at all costs number 13 cantharidin cantharidin has an LD50 of 0.5 milligrams per kilogram with amounts as small as 10 50 reportedly milligrams are fatal to adult humans So far, we've seen a killer tree and a spiteful mushroom, so why not introduce an inflammatory beetle while we're at it?
No matter where you live, you've probably at least seen a blister beetle once and they've certainly earned their name as the can't Arden they carry will leave painful blisters on contact with skin, so make sure you don't crush one if falls on you, the blister beetles actually carry enough can't Arden be potentially fatal if only a few of them are eaten, which would be incredibly painful as cantharidin causes death through inflammation of the gastrointestinal and renal tracts number 12 tetrodotoxin the ld50 of TTX or also
knownas tetrodotoxin, is only point three three four milligrams per kilogram, so only 26 milligrams is fatal to most adult humans, making TTX 100 times more deadly than tetrodotoxin.
Sodium cyanide. suffocation and death usually within 20 minutes to 10 hours many different types of marine animal species carry this toxin, including newts, blue-ringed octopus, and puffer fish, it should be noted that TTX is not produced by marine species themselves, but by the symbiotic bacteria that live with them number 11 alpha amanitin alpha ammonite UNS ld50 is only point one milligrams for rats, meaning just a few milligrams is enough to be fatal to most adults humans. half a bowler hat is enough to be potentially fatal to someone left untreated. It's the lack of symptoms after consuming the mushrooms, as it takes 5-24 hours before symptoms appear, which usually equates to cramps and diarrhea, which eventually subsides, that doesn't sound too bad, oh wait , there is more at this point. it makes no sense and treatment options are limited Oh, after about 5-10 days, the liver and kidneys fail, leading to respiratory failure and eventually death.
Those who manage to survive usually suffer permanent liver damage, so don't go eating random mushrooms kids number 10 pH T X 3 the ld50 of the venom carried by the Brazilian wandering spider is 0.134 milligrams per kilogram, so it can kill most from humans in doses as low as 11 milligrams pH T X 3 or Phoneutria a nuclear event or toxin 3 is our neurotoxin found only in the Brazilian wandering spider z -- and leads to inability to control muscles paralysis and eventually death from suffocation PHT X 3 lethality makes the Brazilian wandering spider the most venomous spider in the world, however the doses of venom the spider releases are generally not fatal to adults as the fangs are our design to small prey, though when not hunting these spiders like to hide in dark places including banana trees sometimes landing aggressively. spiders on the counter of a family thousands of miles away at that point all bets are off and it's the spider vs world number nine the sea wasp now we have come to the
toxinswhich have ld50 measured in micrograms ie in millionths of a gram The tentacles of this species of box jellyfish have an ld50 of 40 micrograms per kilogram, making just 3 milligrams of its toxic sting enough to kill an adult human.
The sea wasp's tentacles can reach up to 3 meters in length and are covered with millions of tiny darts filled with microscopic amounts of venom known as cnidocytes, if large enough the sting can cause death after only two to five minutes. excruciating pain, usually due to cardiac arrest or suffocation although if you're ever in the area you'll be lucky to know that wearing pantyhose or scuba gear makes you invisible to jellyfish as the chemicals on your skin are what They activate their tentacles. I'm starting to think that a lot. from marine life dislikes company number 8 paradox n' i know this name is not a clever pun and is abbreviated as p DX wasting all the potential the name had in any case the ld50 for paradox is only 25 micrograms per kilogram, meaning that only 2 milligrams are needed to kill most adults, making it the
deadliesttoxin found in venomous reptiles.
Taipan paradox is another neurotoxin that works by destroying muscle control, leading to paralysis. The Inland Taipan lives only in the southeastern part of Australia and when it wants to kill something it will strike multiple times to poison its prey as much as possible as it does not want to back down from a fight in contrast to many herpetologists who work with the Inland Taipan. they say they are very docile snakes that have been handled correctly and have only gone rambo with their venom at meal number 7 Reisen here is a venom I am sure most of you have heard of ricin by now.
It is a toxin that comes in the form of a protein and therefore wreaks all sorts of havoc on very important functions in your body. of rice in the size of a salt crystal could kill a full grown male the castor bean plant is what produces the especially deadly poison and it is hard to digest rice seeds and it inhibits ribosomal function in the body which means it ceases the most fundamental functions of cell metabolism which obviously leads to death number six two three seven eight tetrachlor die benzo dioxin I'm going to go ahead and refer to it as TCDD from now on TCDD has an ld50 of only one to forty micrograms per kilogram however it is a bit different from all the other
toxinson the list the method of action through which TCDD kills a person is by cancer like lymphoma as it accumulates in the body and takes decades to finally break down it does not just cause cancer but it also causes developmental problems that can also result in birth defects. used in Vietnam and resulted in thousands of people being exposed to TCDD, leading to an increase in cancers and birth defects.
Batrachotoxin number five. Human eyebrow hair is not only BTX a neurotoxin, but it also acts as a cardiovascular toxin just to make things interesting. Now your body can have a race to see which suffocation dies of first. no cardiac arrest remember those blister beetles we talked about earlier in the video, well a different kind of beetle produces this toxin because it doesn't really want to interact with other living things for some reason that didn't stop some birds and frogs. although in fact the poison dart frog uses this toxin that it gets from those 90 beetles every time they prick it or feel pain, the poison dart frog releases a white liquid through the pores on its back that contained deadly toxin number four VX and sarin. why they both don't have exactly the same ld50 with VX being the deadlier of the two but considering they do essentially the same thing I thought it would be boring to list the two very similar compounds separately, VX's ld50 is 1 2 3 micrograms per kilogram and sarin 17 micrograms per kilogram which is pretty scary when you realize both gases are man-made and undetectable by any sense once again we are dealing with neurotoxins though th These are pretty fast acting when inhaled and result in paralysis of the lungs and death by suffocation.
Just 20 years ago a treaty was signed in which countries promised they would destroy their chemical weapons stocks and only fight with more civilized means nuclear warheads weapons and no scopez only number three can carry oxen well we have dealt with everything kinds of animals, insects and even fungi, why not move on to a creature that produces that
deadliesttoxin with an LD50 of only point one three micrograms per kilogram Gambier discus toxic like 'is a kind of dinoflagellate that for some reason, feel the need to make this monstrosity of a molecule hard to pronounce ekeus isn't technically an animal at all, he actually belongs to a large group of weird random organisms known as protists anyway. mate or toxin is not like the other toxins in this video, it not only causes paralysis, it actually triggers a cascade of cell death resulting in painful vomiting muscle spasm However, you will likely never have the misfortune of running into this tiny killer , since they live in temperate ocean waters and produce amounts of the toxin too small to be deadly when alone, number two polonium-210, the ld50 of this isotope is 10 nanograms per kilogram, that is, nanograms, which means that just ten billionth of a gram is enough to knock out 50% of mice, while for humans, an amount of 100 nanograms to 1 microgram is enough to kill the average person. more toxic than sodium cyanide, polonium 210 acts both as a source of lots of alpha radiation and a heavy metal that wreaks havoc in the human body causing DNA damage, today there is only one recorded poisoning with polonium 210 and that is the Interesting case of Alexander Litvinenko, a KGB spy who fled to the UK escaping persecution and sought political asylum before apparently working for MI6 in November 2006.
Alexander suddenly fell ill after a meeting with two former FSB agents. , one of whom likely spiked polonium in his tea and home while visiting Alexander, would later die, as there is no antidote for polonium-210 poisoning, the number one botulinum toxin with an incredible ld50 of 1.3 to 2.1 nanograms per kilogram of botulinum. by far the deadliest toxin known to man, as it takes only 100 to 164 nanograms to kill an adult human when injected or about ten times as much when inhaled. This makes botulinum toxin 5 to 10 million times more deadly than sodium cyanide. they are responsible for producing the deadliest toxin currently known to man along with three other toxins that are also deadly to humans.
Spores of these bacteria are found all over the world on floors and countertops, even after cleaning. by nature it is present everywhere, but why aren't we all dying due to the toxin of bacteria? Fortunately, Clostridium is not an anaerobic bacterium and cannot grow. in the presence of oxygen, not only that, but the bacteria that produced the toxin are 20 times smaller than our own cells and produce less than nanograms of toxin at a time, so we get botulism instead of just dying from it. get in contact. With them, fortunately for us, medical advances have reduced the death rate of people infected with botulism from 70% in the early 1900s to just one to two percent today.
There is still some concern that purified botulinum toxin could be used in abioterrorist attack in which case just a few grams could wipe out hundreds of millions of people have fun try not to be paranoid with that knowledge until the next video bye
