Poisons are available to people. The most poisonous animals on planet Earth - list, photos and characteristics

The Swiss physician and alchemist Paracelsus famously said: “All substances are poisons; there is not one that is not. The right dose makes the difference between the poison,” and he’s right. Even too much water will kill you. However, some substances require very small amounts to cause death - sometimes just enough for a drop to fall on a gloved hand - which is why they initially fell into the class of poisons. From flowers to heavy metals, from man-made gases to actual poison, here are the 25 most dangerous poisons known to mankind.

25. Cyanide can be in the form of a colorless gas or crystals, but in either case it is quite dangerous. It smells like bitter almonds, and once ingested, it can cause symptoms such as headache, nausea, rapid breathing and increased heart rate, and weakness in just a few minutes. If left untreated, cyanide kills because cells are deprived of oxygen. And yes, cyanide can be obtained from apple seeds, but don't worry if you eat a few. You will need to eat about ten kernels before you have enough cyanide in your body for it to have a negative effect. Please don't do this.

24. Hydrofluoric acid (Fluoric acid) is a poison used, among other things, in the production of Teflon. In its liquid state, this substance can easily seep through the skin into the bloodstream. In the body, it reacts with calcium and can even destroy the underlying bone. The scary thing is that the contact doesn't cause any pain at first, leaving more time and opportunity for serious damage to occur.

23. Arsenic is a naturally occurring crystalline semimetal and perhaps one of the best known and most common poisons used as a murder weapon in the late 19th century. However, its use for such purposes began in the mid-1700s. Arsenic poisoning can cause death within hours or days. Symptoms of poisoning include vomiting and diarrhea, which made it difficult to distinguish arsenic poisoning from dysentery or cholera 120 years ago.

22. Belladonna or Deadly Nightshade is a very poisonous herb (flower) with a very romantic story. What makes it poisonous is an alkaloid called atropine, and the entire plant is poisonous, with the root containing the most poison and the berries the least. However, even two eaten are enough to kill a child. Some people use belladonna for relaxation as a hallucinogen, and in Victorian times women would often drop belladonna tincture into their eyes to dilate their pupils and make their eyes sparkle. Before you die under the influence of belladonna, you may experience a seizure, increased heart rate, and confusion. Don't play with belladonna, kids.

21. Carbon monoxide (carbon monoxide) is an odorless, tasteless, colorless substance and slightly less dense than air. It will poison and then kill you. Part of what makes carbon monoxide so dangerous is that it is difficult to detect; sometimes called the "silent killer". This substance prevents the body from delivering oxygen to where it is needed, such as to cells, to keep them alive and functioning. Early symptoms of carbon monoxide poisoning are similar to the flu without fever: headache, weakness, drowsiness, lethargy, insomnia, nausea and confusion. Fortunately, you can purchase a carbon monoxide detector at almost any specialty store.

20. The deadliest tree in all of North America grows in Florida. Otherwise, where else would he grow? The Manchineel tree or Beach apple tree has small green fruits that look like apples and look like they would taste sweet. Don't eat them. And don't touch this tree. Don't sit next to it or under it, and pray you never end up in the wind under it. If the sap gets on your skin, it will blister, and if it gets in your eyes, you may go blind. The juice is contained in both the leaves and the bark, so do not touch them. Probably, the juice of this plant killed the conquistador Ponce de Leon, who discovered Florida.

19. Fluorine is a pale yellow gas that is highly poisonous, corrosive and will react with almost anything. For fluorine to be lethal, a concentration of 0.000025% is sufficient. It causes blindness and asphyxiates the victim like mustard gas, but its effects are much worse.

18. The pesticide used is Compound 1080, also known as sodium fluoroacetate. It is found naturally in several plant species in Africa, Brazil and Australia. The scary truth about this deadly, odorless and tasteless poison is that there is no antidote for it. Oddly enough, the bodies of those who die from ingesting this poison remain poisonous for a whole year.

17. The most dangerous man-made poison is called dioxin, and it only takes 50 micrograms to kill an adult. It is the third most toxic poison known to science, 60 times more toxic than cyanide.

16. Dimethylmercury (a neurotoxin) is a terrible poison because it can penetrate most standard protective equipment, such as thick latex gloves. This is exactly what happened to a female chemist named Karen Wetterhahn in 1996. A single drop of colorless liquid fell on my gloved hand, and that was it. Symptoms began to appear FOUR MONTHS later, and six months later she was dead.

15. Wolfsbane (Fighter) also known as "Monk's Hood", "Wolfsbane", "Leopard's Venom", "Women's Curse", "Devil's Helm", "Queen of Poisons" and "Blue Rocket". In fact, it is an entire genus of over 250 herbs, and most of them are extremely poisonous. The flowers can be either blue or yellow, and while some of the plants are used for traditional medicine, it has also been used as a murder weapon over the past decade.

14. The toxin found in poisonous mushrooms is called amatoxin. It attacks liver and kidney cells and kills them within a few days. Sometimes it also affects the heart and central nervous system. Treatment is available, but results are not guaranteed. The poison is temperature stable and cannot be removed by drying. So unless you are 100% sure they are safe, don't eat mushrooms.

13. Anthrax is actually caused by a bacterium called Bacillus anthracis. What makes you sick is not so much the bacteria, but the toxin they produce when they enter the body. Bacillus Anthracis can enter your system through the skin, mouth, or respiratory tract. The mortality rate from airborne anthrax reaches 75% even with treatment.

12. The hemlock plant is a classic poisonous plant that was regularly used for executions in ancient Greece, including the philosopher Socrates. There are several varieties, and in North America, water hemlock is the most common plant. You could die from eating it, but people still do it, thinking hemlock is a perfectly acceptable salad ingredient. Water hemlock causes painful and severe convulsions, cramps and tremors. Those who survive may subsequently suffer amnesia or other long-term problems. Water hemlock is considered the deadliest plant in North America. Serious note: Supervise your children, even older ones, when they are outside. Don't eat anything unless you are 100% sure it is safe.

11. Strychnine is commonly used to kill small mammals and birds, and is often the main ingredient in rat poison. In large doses, strychnine can also be fatal to humans. It can be swallowed, inhaled, or enter the body through the skin. The first symptoms: painful muscle cramps, nausea and vomiting. Muscle contractions ultimately lead to suffocation. Death can occur within half an hour. This is a very unpleasant way to die, for both humans and rats.

10. Most of those who understand such things consider maytotoxin to be the most powerful marine toxin. It's found in a dinoflagellate algae called Gambierdiscus toxicus, and if those words confuse you, just think of deadly plankton to get the idea. For mice, meiototoxin is the most toxic among non-protein toxins.

9. Mercury, the silvery liquid in old school thermometers, is a heavy metal that is quite toxic to humans if inhaled or touched. If you touch it, it can cause your skin to peel off, and if you inhale the mercury vapor, it will eventually shut down your central nervous system and you will die. Before then, you are likely to experience kidney failure, memory loss, brain damage and blindness.

8. Polonium is a radioactive chemical element and has been implicated in the deaths of everyone from Yasser Arafat to Russian dissidents. Its most common form is 250,000 times more toxic than hydrocyanic acid. It is radioactive and emits alpha particles (they are not compatible with organic tissues). Alpha particles cannot penetrate the skin, so polonium must be ingested or injected into the victim. However, if this happens, the result will not be long in coming. One theory is that a gram of polonium 210 could kill up to ten million people if injected or ingested, causing first radiation poisoning and then cancer.

7. Suicide tree or Cerbera odollam acts by disturbing the natural rhythm of the heart and often causing death. A member of the same family as Oleander, the plant was often used to perform the "innocence test" in Madagascar. An estimated 3,000 people a year died from drinking Cerberus poison before the practice was outlawed in 1861. (If you survived, you were found innocent. If you died, it didn't matter because you were dead).

6. Botulinum toxin is produced by the bacterium Clostridium Botulinum, and it is an incredibly powerful neurotoxin. It causes paralysis, which can lead to death. You may know botulinum toxin by its commercial name, Botox. Yes, that's what the doctor injects into your mom's forehead to make it less wrinkled (or into her neck to help with migraines) to cause muscle paralysis.

5. Pufferfish is considered a delicacy in some countries, where it is called Fugu; it's a dish that some would literally die for. Why? Because the insides of the fish contain tetrodotoxin, and in Japan, approximately 5 people a year die from eating puffer fish as a result of improper preparation technology. But gourmets continue to persist.

4. Sarin gas will give you the opportunity to survive the worst moments of your life. Your chest tightens, tighter, tighter, and then... it relaxes because you are dead. Although Sarin was outlawed in 1995, it has not stopped being used in terrorist attacks.

3. Golden Poison Arrow Frog - Tiny, adorable and quite dangerous. Just one frog the size of the end of your thumb contains enough neurotoxin to kill ten people! A dose equal to about two grains of salt is enough to kill an adult. This is why some Amazon tribes used poison to coat the tips of their hunting arrows. One touch of such an arrow will kill you within minutes! Here's a great rule: if you see a frog and it's yellow, blue, green or red, don't touch it.

2. Ricin is more lethal than anthrax. This substance is obtained from the castor bean, the same plant from which we obtain castor oil. This poison is especially toxic if inhaled, and a pinch of it will kill you very quickly.

1. Codenamed “Purple Possum”, a VX gas, is the most powerful nerve gas on Earth. It is entirely man-made and we can thank the United Kingdom for that. It was technically banned in 1993, and the US allegedly destroyed its stockpile. Other countries are “working on it.” Which we should trust completely because governments are known to be 100% honest about these things.

Let's start with the “king” of poisons – Arsenic. Until 1832, arsenic poisoning was extremely difficult to diagnose, since the symptoms of poisoning with this poison were similar to those of cholera. This similarity made it possible to mask the use of arsenic and its compounds as a deadly poison.

In acute arsenic poisoning, vomiting, abdominal pain, diarrhea, and depression of the central nervous system are observed.

Antidote: aqueous solution of sodium thiosulfate, dimercaprol.

Cyanide

Potassium cyanide, or potassium cyanide, is the most powerful inorganic poison. It looks like granulated sugar.

When it enters the body, the cells stop absorbing oxygen, resulting in the body dying from interstitial hypoxia. Potassium cyanide is absorbed very quickly and therefore death occurs within 15 minutes.

Sarin gas

Sarin gas is a poisonous substance with a nerve-paralytic effect.

The first signs of exposure to sarin include nasal discharge, chest congestion, and constriction of the pupils. Soon after this, the victim has difficulty breathing, nausea and increased salivation. The victim then completely loses control over bodily functions. This phase is accompanied by convulsions. Ultimately, the victim falls into a comatose state and suffocates in a fit of convulsive spasms followed by cardiac arrest.

Antidote: Atropine, Pralidoxime, Diazepam, Athens.

Diamphotoxin

Diamphotoxin is the most powerful poison of animal origin on our planet, contained in the blood of the larvae of the South African leaf beetle.

It is capable of reducing the hemoglobin content in the blood by 75% in a short period of time due to the massive destruction of red blood cells.

Antidote: There is no specific antidote.

Ricin

Ricin is the most powerful poison of plant origin, which is obtained from castor beans of the castor bean plant.

A few grains are enough to kill an adult. Ricin kills cells in the human body, preventing it from producing the proteins it needs, resulting in organ failure. A person can become poisoned by ricin through inhalation or ingestion.

If inhaled, symptoms of poisoning usually appear within 8 hours of exposure and include difficulty breathing, fever, cough, nausea, sweating and chest tightness.

If ingested, symptoms appear in less than 6 hours and include nausea, low blood pressure, hallucinations and seizures. Death can occur within 36-72 hours.

Antidote: There is no specific antidote.

The world-famous medieval physician and alchemist Paracelsus once said: “Everything is poison, everything is medicine; both are determined by the dose.” Even too much water can cause death. However, some substances will require a tiny amount - this will be enough to cause death. Sometimes just one drop is enough to fall on hands unprotected by gloves - these are the substances that are classified as very toxic. Deadly substances include organic plant substances, heavy metals, and man-synthesized gases. We have prepared for you a list of the most dangerous of them - the 25 most deadly toxic substances.

The most poisonous substance in the world for humans is cyanide.

The most common forms of cyanide are a colorless gas or crystals, but regardless of the form, the substance is deadly. To some people, cyanide smells like bitter almonds.

Cyanide poisoning is accompanied by characteristic symptoms: headache, nausea, rapid breathing, rapid heartbeat, and a feeling of general malaise. Without timely medical intervention, cyanide will kill the body, causing oxygen starvation of cells. Vial of cyanide

Cyanide is contained in apple seeds, but do not rush to rinse your stomach after eating a few seeds - the concentration of the dangerous substance in them is extremely insignificant. You would have to eat more than ten whole apple stalks before you feel the effects of cyanide poisoning. But, of course, you shouldn’t do this.

Hydrofluoric acid, or hydrofluoric acid, is a chemical required to produce polytetrafluoroethylene, more commonly known as Teflon. It is also an extremely toxic poison.
Container with hydrofluoric acid

If a liquid containing even a small amount of hydrofluoric acid gets on the skin, there is a high probability that the poison will enter the circulatory system through the capillaries. When it reacts with calcium, it will begin to break down your bones.

Fortunately, getting this substance on the skin is painless, and the process of penetration through the skin is not instantaneous, so you will have enough time to wash this dangerous substance off yourself.

Arsenic has been known since ancient times. It occurs naturally in pure form and in the form of sulfides. It is a crystalline semimetal in form. Medieval alchemists, including the already mentioned Paracelsus, were involved in the synthesis of arsenic.
Glass vial of arsenic

This substance, until the end of the 19th century, was the most common poison used to commit murders. A victim poisoned with arsenic dies from several hours to several days. This practice dates back to the Late Middle Ages and the Renaissance. The characteristic symptoms of arsenic poisoning were severe vomiting and diarrhea, which at the time could easily be confused with symptoms of cholera or dysentery.

Belladonna

This plant has also been known since ancient times, and it was used both in Europe and in Rus'. All parts of belladonna are very toxic, especially the roots. The least poisonous are the berries, and yet two berries will be enough to kill a one-year-old child.
Belladonna berries, flowers and leaves

In medieval Italy, the juice of this plant was dropped into the eyes of local fashionistas - thanks to the atropine content in it, the pupils dilated, and the gaze acquired an alluring shine. At the same time, it is atropine alkaloids that lead to poisoning - they actively affect the nervous system, first provoking an excited state, and then leading to rage and cardiac arrest. It’s not for nothing that one of the names of this plant is Crazy Berry.

Carbon monoxide or carbon monoxide is a silent killer. The physical form of this substance is a gas without taste, color or smell. This gas is released when coal is burned, for example - it is the cause of many deaths in fires.
Clipping from an old magazine warning about the dangers of carbon monoxide

This substance disrupts the process of oxygen transfer, which causes oxygen starvation in cells. Symptoms of poisoning are general physical weakness, dizziness and headache, nausea, drowsiness. Fortunately, carbon monoxide poisoning is reversible - timely resuscitation measures can “bring back to life” a person who has inhaled carbon monoxide.

The fruits of the Manchineel tree, also called manchinella, look like green apples, but don’t rush to taste them. It's best to stay away from this tree altogether - it is one of the most poisonous plants on Earth and certainly the most poisonous in North America.

Manchinella grows in Florida, but you need to be wary of the sap of this tree. Even the wind blowing on you from the direction of this terrible plant can lead to severe itching, and contact with the milky juice on the skin will cause painful blisters, dermatitis and severe burns. Smoke from burning branches of this tree can cause blindness if it comes into contact with the eyes. Well, it’s not worth talking about the fruits.
Manchineel tree danger warning

Interesting fact: local Indians, during the Spanish conquest of these lands, used an extract from manchinella root as one of the components of a terrible poison, which was used to smear arrowheads. The famous Spanish conquistador Juan Ponce de Leon died long and painfully from one such arrow that hit him in the leg.

This substance is the most active non-metal, interacting with literally anything. If it comes into contact with the skin, such gas will cause a severe chemical burn. It can also contribute to eye damage, including blindness. If you are interested in organic chemistry, remember that fluorine is not to be trifled with.

This compound is found both in industrial pesticides and in the sap of some plants in Australia and South Africa (Dichapetalum cymosum). Consumption of the latter leads to the death of about 8% of livestock grazing in the areas where it grows. What is characteristic is that there is no antidote for this substance. For humans, the lethal dose is 5 mg per 1 kg.
Fluoroacetic acid warning

The most dangerous poison created by man is called dioxin - only 50 micrograms are required for an adult. This is the third most toxic poison known to science - it is 60 times more toxic than cyanide!
Warning about contamination of the area with dioxins

This substance, or rather a whole group of substances, denoted by a single term for ease of perception, belongs to the group of xenobiotics, that is, substances alien to the natural biotic substances of the Earth. This is a consequence of the chemical industry and waste recycling. Dioxins are also a cumulative poison, that is, they gradually accumulate both in the environment and in the bodies of living beings, leading to terrible changes.

Dimethylmercury

This colorless liquid is a powerful neurotoxin. Even thick latex gloves will not save you from its effects. This fact was confirmed by the tragic death of inorganic chemist Karen Wetterhahn in 1996. A few drops of the substance that fell on the scientist’s glove led to death - after 4 months, symptoms of poisoning began to appear, and six months later the woman died.

Aconite, also known as Fighter, is a whole family of plants, many of which are prized for their beautiful flowers. However, all of them are extremely toxic, however, this only applies to juice. The most poisonous parts of plants are the tubers; the active substance is the aconitine alkaloid.
Aconite plant containing aconitine

According to legend, these plants sprouted from the saliva of Cerberus, whom Hercules brought from the underground kingdom of Hades. What does this legend indicate? The fact that the plant was widely known already in Ancient Greece.

Some modern “healers” promote the idea of ​​treating cancer and many other diseases with tincture of aconite. The clinical effectiveness of this treatment has not been proven and is associated with risks to your health.

Substances of this group are found in poisonous mushrooms, including toadstool, among others. The effect of this poison on the body is extremely destructive - the work of the gastrointestinal tract, kidneys and heart is paralyzed. Necrosis of liver tissue occurs.
Pale toadstools containing amatoxin

In case of poisoning, the first symptoms appear very sharply after 5 hours or more - depending on the degree of poisoning, its active phase can begin even after a day. The condition is rapidly deteriorating - bloody diarrhea, terrible pain in the abdominal cavity, severe vomiting. Mushroom poisoning with amatoxin in most cases is severe and requires immediate medical intervention.

Three out of four people who contract this bacterium die, even if they are hospitalized and treated. You can become infected from livestock used in agriculture. However, the disease is very acute, so that foci of infection, if they occur, can be promptly identified and destroyed, along with the carriers.

Hemlock

You may know this plant under the name Hemlock, or Omega. It is a distant relative of celery and is the carrier of one of the most powerful poisons in the plant kingdom. According to legend, the ancient Greek thinker Socrates was once poisoned with it.

This plant is popular as a murder weapon. Most often it is added to the victim's food under the guise of salad. Poisoning leads to severe convulsions, pain and death. Even if the poisoned person survives, the consequences in the form of amnesia, severe tremors and clouding of reason can haunt him for the rest of his life.
Hemlock plant containing hemlock

At the beginning of the 19th century, medicines based on hemlock were used as an anesthetic.

This is the main ingredient of rat poison, a powerful pesticide. It was synthesized from the seeds of the tropical chilibuha tree, also known as the vomit nut. Strychnine will have no less effective effect on humans than on pests - death from a dose of 50 mg can occur for an adult half an hour after poisoning.
Strychnine bottle

You can become poisoned by strychnine by inhaling its fumes, applying it to the skin, or inadvertently taking it orally. Symptoms appear almost immediately - vomiting and painful convulsions.

Strychnine is one of the most popular poisons, often appearing in literary works, cinema and even comics.

A powerful paralytic poison produced by dinophyte algae. The most potent non-protein toxin, having the most complex cell structure for a non-protein compound produced by a living organism.
Dinoflagellates - plankton that produce maytotoxin

In addition, it is the most terrible “sea” poison. Its source is essentially plankton. Fortunately, poisoning requires an extremely high concentration of these microorganisms, so the risk of accidental poisoning is virtually zero.

Previously, mercury was actively used in thermometers and medical thermometers. Moreover, mercury is the only volatile metal whose vapor poisoning can be fatal. Mercury can cause tissue necrosis, blindness, kidney failure, amnesia and central nervous system paralysis.
This is what liquid mercury looks like

Interesting fact: after analyzing the remains of Tsar Ivan the Terrible, scientists came to the conclusion that the last representative of the Rurik family was poisoned with mercury for a long time, from which he eventually died.

Another deadly metal, but this time it is radioactive. In the last 50 years it has been a popular weapon for demonstrative murder. Alexander Litvinenko, Yasser Arafat, Alexander Goldfarb and others died from polonium poisoning.
Polonium in its natural state

Polonium-210 is 250 thousand times more toxic than hydrocyanic acid. For the death of an adult male, 10 mcg of this isotope entering his body will be sufficient. So, to kill ten million people you would need about a gram of polonium. Typically, the alpha particles of this substance are not able to penetrate the skin, so for polonium poisoning it is necessary to enter the body, for example, through the respiratory tract or oral cavity.

This poison is found in all parts of Cerberus trees, named after the guardian of the gates of the kingdom of Hades. Even the smoke from this tree can cause serious poisoning. The effect of the poison leads to cardiac arrest.
Fruits of the Cerberus tree

In Madagascar, until 1861, eating Cerberus fruits was used in trials and was a kind of analogue of the “witch bath” of medieval Europe. If the accused survived after taking it, he was considered innocent, but if he did not survive, it is obvious that guilt can be considered proven.

Botulinum toxin

The most powerful organic poison, neurotoxin. For an adult, the lethal dose will be approximately 0.05 mcg. Entering the body leads to paralysis and further death.
In this form, butulinum toxin is used in aesthetic medicine.

Botox, used in aesthetic medicine, is butulinum toxin, albeit slightly modified.

The bacteria Clostridium botulinum, which produces butulinum toxin, prefer an airless environment. That is why, when spores penetrate canned twists, they activate vital processes, releasing a deadly poison.

Tetrodotoxin

This is the world-famous poison of fugu fish, considered a delicacy in Japan. Once in the body, tetrodotoxin causes respiratory arrest. There is no antidote, but the poisoned person can be saved by supporting the functioning of the respiratory system artificially for some time. However, every year in Japan, several people die from fugu fish poisoning. Several dozen more people are saved.
Fugu fish contains deadly tetrodotoxin

Fugu fish does not produce tetrodotoxin, but only accumulates it from the plankton it consumes, the toxicity of some species of which we have already discussed earlier.

Chemical weapons, military nerve gas. It was created in the mid-30s and was used on the battlefields of World War II and in wars of recent history and major terrorist attacks. It was recognized as a weapon of mass destruction.
US Honest John missile demonstration warhead, showing M139 sarin canisters (circa 1960s photo)

This gas is colorless, tasteless and odorless. Death from sarin poisoning is terrible and very fast. Antidotes exist, but comprehensive treatment of those poisoned by sarin on the battlefield is virtually impossible. Sarin is one of the substances prohibited from production and stockpiling under the Chemical Weapons Convention adopted by the UN in 1997.

This poison is produced by a small yellow frog that lives in the tropical forests of southwestern Colombia - the Terrible Leaf Climber. The poison secreted by the skin glands of the frog and serving as its protection from predators is one of the strongest organic non-protein poisons.
A terrible leaf climber that produces batrachotoxin

The action of the poison paralyzes the respiratory system, muscles and heart, causing it to stop. Local Indians use this poison by running a blowpipe dart across the frog's back. After being wounded by such a dart, a person dies in less than 10 minutes. There is no effective antidote, but scientists have now developed synthetic analogs of batrachotoxin that are twice as toxic.

One of the strongest phytotoxins. It is especially dangerous in aerosol form. Found naturally in castor beans and castor beans. You probably know another derivative of this plant - castor oil.
Castor beans containing ricin

The toxicity of ricin is 6 times higher than that of potassium cyanide. Of course, this substance is used as a weapon. The most resonant case of its use is the murder of the Bulgarian dissident Georgiy Markov.

VI-gas

Chemical warfare agent VX is the most powerful man-made poison ever synthesized by man. Weapons based on this gas are still in service with the armies of the United States and Russia, although according to official data, in 2017 the Russian army completely destroyed its stockpiles of chemical weapons, including VX and its analogues.
This is what the storage facility for the most terrible chemical weapons on Earth looks like

It was this poison that killed the half-brother of Kim Jong-un, the leader of North Korea, at Kuala Lumpur International Airport in 2017.

As you can see, there are enough dangerous substances of organic origin in the world. But the most powerful poisons are created by man. Today there are several international agreements prohibiting the production and condemning the use of chemical weapons. But its reserves are still large and cases of its use continue to be recorded. How to avoid becoming a victim of poisoning with the substances described in this article? Be vigilant when working with various chemical reagents, do not eat puffer fish meat, do not pet toads, and hope that the “powers that be” will have enough prudence to never use any of the arsenal of weapons of mass destruction that they have at their disposal.

There are many poisons of various natures in the world. Some of them act almost instantly, others can torment the victim of poisoning for years, slowly destroying him from the inside. True, the concept of poison has no clear boundaries. It all depends on concentration. And often the same substance can act both as a deadly poison and as one of the most necessary components for maintaining life. A striking example of such duality are vitamins - even a slight excess of their concentration can completely destroy health or kill on the spot.

Here we propose to take a look at 10 substances that are classified as pure poisons, and are among the most dangerous and fast-acting.

Cyanide

Cyanides are a fairly large group of hydrocyanic acid salts. They are all, like the acid itself, extremely poisonous. In the last century, both hydrocyanic acid and cyanogen chloride were used as chemical warfare agents and were responsible for tens of thousands of deaths.
Potassium cyanide is also famous for its extreme toxicity. Just 200-300 mg of this white powder, which resembles granulated sugar in appearance, is enough to kill an adult in just a few seconds. Thanks to such a small dosage and incredibly quick death, this poison was chosen to kill Adolf Hitler, Joseph Goebbels, Hermann Goering and other Nazis.
They tried to poison Grigory Rasputin with this poison. True, the senders mixed cyanide into sweet wine and cakes, not knowing that sugar is one of the most powerful antidotes for this poison. So in the end they had to use the gun.

Bacillus anthrax

Anthrax is a very serious, rapidly developing disease caused by the bacteria Bacillus anthracis. There are several forms of anthrax. The most “harmless” one is the skin one. Even without treatment, the mortality rate from this form does not exceed 20%. The intestinal form kills about half of those sick, but the pulmonary form is almost certain death. Even with the help of the latest treatment methods, modern doctors manage to save no more than 5% of patients.

Sarin

Sarin was created by German scientists trying to synthesize a powerful pesticide. But this deadly poison, which causes quick but very painful death, acquired its dark fame not in agricultural fields, but as a chemical weapon. Sarin was produced by the ton for military purposes for decades, and it was only in 1993 that its production was banned. But despite calls for the complete destruction of all stocks of this substance, both terrorists and the military still use it in our time.

Amatoxins

Amatoxins are a whole group of protein poisons contained in poisonous mushrooms of the amanita family, including the deadly toadstool. The particular danger of these poisons lies in their “slowness”. Once they enter the human body, they immediately begin their destructive activity, but the victim begins to feel the first discomfort no earlier than 10 hours later, and sometimes several days later, when it is already very difficult for doctors to do anything. Even if such a patient can be saved, he will still suffer for the rest of his life from painful dysfunctions of the liver, kidneys and lungs.

Strychnine

Strychnine is found in large quantities in the nuts of the tropical chilibuha tree. It was from them that it was obtained in 1818 by the French chemists Pelletier and Cavantou. In small doses, strychnine can be used as a medicine that increases metabolic processes, improves heart function and treats paralysis. It was even actively used as an antidote for barbiturate poisoning.
However, it is one of the most powerful poisons. Its lethal dose is even less than the famous potassium cyanide, but it acts much more slowly. Death from strychnine poisoning occurs after about half an hour of terrible agony and severe convulsions.

Mercury

Mercury is extremely dangerous in all its manifestations, but its vapors and soluble compounds cause especially great harm. Even small amounts of mercury entering the body cause severe damage to the nervous system, liver, kidneys and the entire gastrointestinal tract.

When small amounts of mercury enter the body, the process of poisoning occurs gradually, but inevitably, since this poison is not eliminated, but rather accumulates. In ancient times, mercury was widely used for the production of mirrors, as well as felt for hats. Chronic poisoning with mercury vapor, expressed in behavioral disorders up to complete insanity, was at that time called “the old hatter’s disease.”

Tetrodotoxin

This extremely strong poison is found in the liver, milk and caviar of the famous puffer fish, as well as in the skin and caviar of some species of tropical frogs, octopuses, crabs and in the caviar of the Californian newt. Europeans first became acquainted with the effects of this poison in 1774, when the crew on James Cook's ship ate an unknown tropical fish, and the slops from the dinner were given to the ship's pigs. By morning, all the people were seriously ill, and the pigs died.
Tetrodotoxin poisoning is very serious, and even today doctors manage to save less than half of all those poisoned.

It is interesting to note that the famous Japanese delicacy fugu fish is prepared from fish in which the content of the most dangerous toxin exceeds lethal doses for humans. Lovers of this treat literally entrust their lives to the art of the cook. But no matter how hard the chefs try, accidents cannot be avoided, and every year several gourmets die after feasting on a delicious dish.

Ricin

Ricin is an extremely powerful poison of plant origin. The greatest danger is inhaling its smallest grains. Ricin is about 6 times more powerful a poison than potassium cyanide, but it has not been used as a weapon of mass destruction due to purely technical difficulties. But various intelligence services and terrorists “love” this substance very much. Politicians and public figures receive letters filled with ricin with enviable regularity. True, the case quite rarely ends in death, since the penetration of ricin through the lungs is quite low in efficiency. For a 100% result, it is necessary to inject ricin directly into the blood.

Vi-Ex (VX)

VX, or, as it is also called, VI gas, belongs to the category of chemical warfare gases that have a nerve-paralytic effect. It was also born as a new pesticide, but soon the military began to use it for their own purposes. Symptoms of poisoning with this gas appear within 1 minute after inhalation or contact with skin, and death occurs within 10-15 minutes.

Botulism toxin

Botulinum toxin is produced by Clostridium botulinum bacteria, which are the causative agents of the most dangerous disease - botulism. This is the most powerful poison of organic nature and one of the strongest poisons in the world. In the last century, botulinum toxin was part of the arsenals of chemical weapons, but at the same time, active research was conducted regarding its use in medicine. And today, a huge number of people who want to at least temporarily restore the smoothness of their skin are experiencing the influence of this terrible poison, which is part of the popular drug Botox, which once again confirms the validity of the famous saying of the great Paracelsus: “Everything is poison, everything - medicine; both are determined by the dose.”

Poisonous substances lie in wait for us everywhere. Some of them have an almost immediate effect, while others can act slowly. The degree of intoxication in each specific case is different. It depends on the characteristics of the body and the amount of poison that has entered the body. Therefore, determining the most powerful poison in the world is problematic. Nevertheless, we can highlight a list of toxic substances that pose the greatest danger.

The most powerful poisonous chemicals

Potent poisons have been synthesized by scientists for military purposes. But sometimes toxic substances can be found in everyday conditions. Among the most dangerous of them are:

1. Mercury. It is contained in ordinary thermometers. If the integrity of the flask is not compromised, then mercury does not pose any health hazard. Mercury vapor from a broken thermometer can cause irreparable harm. The evaporation process begins even at room temperature. It is prohibited to collect spilled mercury yourself. You must immediately seek help from a specialized service.
2. Methanol. This substance is often confused with food grade ethyl alcohol, which leads to serious poisoning. Methanol is colorless and odorless, so it is impossible to identify it without laboratory testing. Consumption of even a small amount of this substance can be fatal. a person loses his sight.
3. Potassium cyanide. This is the most powerful poison for humans. It is widely used in plastic products, photography, gold mining and some other fields. Poisoning occurs even from inhaling cyanide vapor. In the shortest possible time, respiratory failure develops and convulsions appear. In case of severe intoxication, death occurs.
4. Sarin. This is a substance that was synthesized by German scientists. They pursued the goal of creating the world's strongest pesticide. The resulting gas has gained fame as a poison that causes a long and painful death. Today, the deadly poison sarin is officially banned, but terrorists are trying to use it as a chemical weapon.
5. Arsenic. This element of the periodic table has long been used as a poison. Many political figures were poisoned with it. Symptoms of poisoning are similar to cholera. First of all, cramps and severe pain appear in the abdominal area. After large amounts of arsenic enter the body, heart disease, diabetes or cancer develop.

These substances are extremely dangerous for humans. Therefore, their features must be remembered.

The most dangerous poisons for humans are also found in plants. Such poisonings often await inexperienced mushroom pickers and other flora lovers. The following substances deserve special attention:

1. Amatoxin is the most powerful protein poison. It is found in some mushrooms, including toadstool. Once in the human body, the toxin immediately begins to destroy internal organs. The first signs of intoxication may appear only after a few days. In this case, valuable time to save a person is lost, and doctors cannot guarantee a favorable prognosis. Even if the patient’s life can be saved, his health will be severely compromised. Most likely, a person will suffer from kidney or liver failure and problems with the respiratory system all his life. People often wonder what is more toxic: toadstool or potassium cyanide. In fact, these poisons can be placed on the same level in terms of toxicity.
2. Strychnine. This poison is found in the nuts of the chilibuha tree. In microscopic dosages it is used for medical purposes. If the permissible amount is exceeded, death occurs, but before this the person experiences severe suffering.
3. Ricin. Contained in castor beans. Inhalation of small grains of this substance is dangerous. Its poisoning ability is several times higher than that of potassium cyanide. Human death occurs if ricin is injected directly into the blood.
4. Curare. It is a poison that is produced from a mixture of plants in South America. Its main component is an alkaloid, which, when ingested, leads to paralysis and cardiac arrest. Death from curare is painful.

To avoid poisoning from such poisons, never eat unknown plants. Teach children about safety precautions when traveling outdoors.

If you notice the first symptoms of poisoning, consult a doctor immediately. Chances of salvation remain only if the problem is identified in a timely manner.

Animal poisons

Poison can kill a person instantly. Such toxic substances are often carried by animals. Among them are:

1. Toads chirp. The skin of these amphibians secretes chiriquitotoxin. This neurotoxin has a toxic effect on the human nervous system. After intoxication, a person experiences severe convulsions, coordination of movements is impaired, and complete paralysis of the limbs may develop. The poison has a strong effect when administered intramuscularly.
2. Puffer fish. The milk, caviar and liver of this fish contain tetrodotoxin. This substance causes severe poisoning, which is accompanied by severe itching, drooling, convulsions, and difficulty swallowing. The poison is fast, so paralysis of the respiratory system develops in the shortest possible time and a person’s death occurs.
3. Australian Taipan. The venom of this snake contains thaipotoxin. Its entry into the human blood leads to paralysis of the respiratory muscles and impaired blood clotting. This kind of snake venom is the most poisonous. In terms of poisoning ability, it is several times greater than cobra venom.
4. Karakurt. During the bite, the spider injects alpha-latrotoxin into the victim's blood. It leads to severe pain that spreads throughout the body in a matter of minutes. At the same time, severe shortness of breath, dizziness, increased heart rate, and bouts of vomiting occur.
5. Central Asian cobra. This snake's saliva contains a powerful neurotoxin. Its entry into the human blood provokes convulsions, breathing problems, and paralysis. If left untreated, death occurs. Such poisonings are rare, since the cobra attacks a person only in exceptional cases.

Poison can be contained in the biological material of any animal. Therefore, it is best to minimize contact with it, especially for wild fauna.

If you are bitten by a poisonous snake or spider, try to immediately suck the poison out of the wound. Remember that this can only be done if there is no damage to the oral cavity. Seek medical help as soon as possible.

Bacteriological poisoning

Not only animals and plants, but also bacteria can pose a danger to humans. Their vital activity in the human body leads to the formation of strong toxins. Among them, the following can be particularly highlighted:

1. Botulinum toxin. It is produced by the bacterium Clostridium botulinum. Its vital activity leads to the development of botulism in humans. This is a disease that can only be treated in its earliest stages. In other cases, the probability of death is extremely high. The bacterium multiplies quickly in the absence of oxygen, so poor quality canned food often becomes a source of poisoning.
2. Anthrax bacillus. Its entry into the body leads to the development of anthrax. This disease develops rapidly. There are cutaneous and intestinal forms. In the first case, death occurs in 20% of cases. With the intestinal form of the disease, no more than 5% of victims can be saved.
3. Tetanus toxin. This substance is produced by rods of the genus Clostridium. Infection most often occurs through open wounds on the body. Infection manifests itself in the form of convulsions, impaired swallowing reflex, damage to the respiratory center and cardiovascular system. The likelihood of death is extremely high.

Determining the fastest-acting poison is quite difficult. Everything will depend on a combination of many factors. Try to avoid contact with hazardous substances as little as possible. If infection does occur, do not try to cure it yourself. Only timely seeking medical help will save your life.
