The most powerful poison. What are the types of human poisoning? Anthrax poison

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. Among the deadly substances there are also organic matter plant nature, and heavy metals, and gases synthesized by man. 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 through the capillaries. circulatory system. 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, up to late XIX centuries, was the most common poison used to commit murder. A victim poisoned with arsenic dies from several hours to several days. This practice dates back to the Late Middle Ages and 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. No wonder one of the names of this plant- Crazy berry.

Carbon monoxide or carbon monoxide is a silent killer. Physical form This substance is a gas without taste, color or odor. 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, poisoning carbon monoxide reversible - timely resuscitation measures can “bring back to life” a person who has inhaled carbon monoxide.

The fruits of the Manchinella tree, also called manchinella, look like green apples, but don’t rush to taste them. It is better 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 ingredients terrible poison, which lubricated arrowheads. From one such arrow that hit the leg, a famous man died for a long time and painfully. spanish conquistador Juan Ponce de Leon.

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're addicted organic chemistry- remember, fluoride is not to be trifled with.

This compound is found both in industrial pesticides and in the sap of some Australian plants 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. It 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 chemical industry and waste recycling. Also, dioxins are a cumulative poison, that is, they gradually accumulate both in environment, and in the organisms 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 confirmed tragic death 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 alkaloid aconitine.
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 get infected from livestock used for 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 a carrier of one of the strongest poisons among 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 mental confusion 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 Rurikovich family for a long time they poisoned him with mercury, 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” 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, used on the battlefields of World War II and in wars modern history and major terrorist attacks. Was recognized as a weapon mass destruction.

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 tropical forests in the southwest of 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 effect of the poison paralyzes work respiratory system, muscles and heart, leading to its 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 reserves 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 “ strong of the world This is enough prudence to never use any of the arsenal of weapons of mass destruction that they have at their disposal.

Foods and drinks that are very familiar to us can turn out to be deadly. And the simplest objects contain poison. It turns out that the most powerful poisons are sometimes close to us, and we don’t even suspect it.

Dangerous poisons

- Methanol, or methyl alcohol is very dangerous poison. This is explained by the fact that it is easy to confuse it with ordinary wine alcohol, since they are indistinguishable in taste and smell. Counterfeit alcoholic drinks are sometimes made from methyl alcohol, but without an examination it is impossible to determine the presence of methanol. Unfortunately, the consequences of consuming such drinks are irreversible; at best, a person becomes blind.

Mercury. Everyone at home has the most common item - mercury thermometer. It turns out that if you spill mercury from two or three thermometers in a medium-sized room, this will be enough to cause serious poisoning. True, elemental mercury itself is not dangerous, its vapors are dangerous, and it begins to evaporate already at room temperature. In addition to thermometers, the same type of mercury is found in fluorescent lamps. So be careful with them.

Snake venom. There are more than two and a half thousand species of reptiles, but only about 250 species are poisonous. The most famous - common vipers, cobras, rattlesnakes, black mambas, small snakes - sand ephs.

People have long found out that snake venom is dangerous only when it enters the human bloodstream. And, since humanity has been dealing with snakes for many millennia, it is not surprising that it was while studying the effects of snake venom on the bodies of animals and people that the first antidote was created in 1895 - anti-snake serum. By the way, there is no universal antidote even in case of poisoning snake venom, for each type of snake, its own antitoxin is created - for the king cobra - one, for vipers - another, for rattlesnakes - a third.

The fastest poison

There are many poisons, but potassium cyanide is still considered one of the fastest-acting. It has been used since ancient times and is probably the most famous "spy" poison: many agents in films and books use cyanide in ampoules or tablets. And everyone probably read about such a sign as the smell of “bitter almonds” in Agatha Christie’s wonderful detective stories.

You can be poisoned by cyanide not only by ingestion, but also by inhalation or touching. Potassium cyanide is found in some plants and foods, as well as cigarettes. It is used in the extraction of gold from ore. Cyanide kills by binding iron in blood cells, thereby preventing them from delivering oxygen to vital organs.

Cyanide can be determined using a solution of ferric salts

By the way, they tried to poison Grigory Rasputin with potassium cyanide, but they couldn’t because they added the poison to a sweet pie. Glucose is an antidote to potassium cyanide.

The most accessible poisons

In summer and autumn, the time comes for seasonal mushroom poisoning - by the way, these are the most accessible poisonous substances today. The most famous poisonous mushrooms are false honey mushrooms, pale grebe, lines and fly agarics. The most poisoned one is the pale grebe, since it has many varieties, sometimes indistinguishable from edible mushrooms, and one such mushroom can lead to the death of several people.

Although the Germans have learned to prepare fly agarics in such a way that they are not poisoned by them, it is true that it takes them a lot of time to prepare these mushrooms - they boil them for days. True, the question arises - why do they need fly agarics when they can simply take other mushrooms for food? And of course, we must remember the rules for storing cooked mushrooms; even edible mushrooms can become poisonous if the shelf life is violated.

Regular potatoes or bread can also be poisonous. When stored improperly, potatoes accumulate the substance solanine, which causes poisoning to the body. And bread becomes poisonous if flour was used to make it and contained cereals contaminated with ergot. We are not talking about fatal poisoning, but it is quite possible to ruin your health with such products.

In addition, there are many household chemicals and fertilizers, which can also cause poisoning. For example, potassium chloride is the most common fertilizer, but if it gets into the blood it becomes deadly, since potassium ions block the activity of the heart.

The most famous poison

In South America, the most famous poison is curare, a poison of plant origin; there are several subspecies of this poison. It causes paralysis of the respiratory system. Initially it was used for hunting animals, but in the 20th century it was successfully used in medicine.

There is also strychnine, a white powder that is sometimes used in some drugs (such as heroin and cocaine). Although it is much more often used in the manufacture of pesticides. To obtain this powder, the seeds of the chilibuhi tree, which is native to Southeast Asia and India, are taken.

But the most famous poison is, of course, arsenic; it can be called the “royal poison”. It has been used since ancient times (its use is also attributed to Caligula) to eliminate their enemies and competitors in the struggle for the throne, no matter the papal or royal one. It was the favorite poison of European nobility in the Middle Ages.

The most famous poisoners

The story of the Italian Borgia dynasty of poisoners, who elevated poisoning almost to the level of art, is unique. Everyone without exception was afraid of their invitation to the feast. The most famous representatives of this family for their treachery are Pope Alexander VI Borgia and his children: son Cesare, who became a cardinal, and daughter Lucrezia. This family had their own poison, "cantarella", supposedly containing arsenic, phosphorus and copper salts. It is known that the head of the family himself ultimately paid with his life for his treachery, having mistakenly drunk a cup of poison that he had prepared for another.

In France, arsenic was used by women, the most famous of them was Catherine de Medici, who became Queen of France. There were also poisoners of lower rank - favorites of kings, marquises, baronesses and wives of jewelers. It is believed that Napoleon was poisoned with arsenic.

The most powerful poison in the world

And now scientists will not answer the question of what poison is the most powerful in the world. Some of the most strong poisons- These are botulism and tetanus toxins.

Among natural poisons, batrachotoxin is very dangerous; it is secreted by the skin of small but dangerous amphibians - dart frogs, fortunately, they can only be found in Colombia. One such frog contains so much poisonous substance that it is enough to destroy several elephants.

In addition, there are radioactive poisons, such as polonium. It acts slowly, but only 1 gram of this substance is needed to destroy one and a half million people. Snake venom, curare, potassium cyanide - they are all inferior to the above poisons.

It's not just snakes that are poisonous. As the editors of the site found out, the most poisonous creature on Earth is the jellyfish.

In nature, there are a huge number of substances that, on the one hand, are dangerous to health, and on the other hand, help to cure various diseases. It all depends on their quantity and concentration. When exposed to poisons in sufficiently small quantities, some of them help to recover from the most dangerous diseases, without any pathologies or consequences.

The most powerful poison

Poisons are quite diverse: some kill a person instantly, while the effects of others are very slow, gradually leading to death for the body. Some even cause severe pain and terrible suffering. There are a huge variety of them; the article lists the most dangerous ones. So dangerous that it is difficult to even determine which poison is the strongest.

Cyanide

Hydrocyanic acid and its derivatives are very dangerous substance for the human body. A very small amount of it can instantly kill a living organism. However, sugar can resist it; it is an antidote.

Anthrax poison

The bacteria that cause this life-threatening disease belong to the Bacillus anthracis family. They attack healthy cells, leading to their death. If a person has a skin form of the disease, then in 20% it leads to death. When affected by the intestinal form of anthrax, 50% of victims die. The pulmonary form leaves virtually no chance for the patient to survive; doctors manage to save only 5%.

Sarin

This substance was obtained as a result of attempts to synthesize pesticides. It is very dangerous; when it enters the body, a person experiences severe suffering, which ultimately leads to death. This poison was used as a chemical weapon for a long time, until its production was stopped in the 90s. But at present it is still used by terrorists and the military.

Amatoxins

These substances are contained in fly agaric mushrooms. A person may only feel symptoms after poison enters the body after 10 hours or even the next day. Amatoxins have a detrimental effect on all organs, so in most cases poisoning is fatal. If a person managed to survive, then for the rest of his life he will be tormented by pain that arises due to internal organs damaged by these substances.

Mercury

This poison penetrates everything internal organs person. tends to accumulate, so with a small amount of it it very slowly poisons the body. When a person is poisoned by this substance, the normal activity of the nervous system is disrupted and severe mental disorder occurs.

Strychnine

It was discovered by chemists back in the 19th century. This toxic substance is obtained from chilibuha nuts. A large amount of it leads to severe poisoning. Subsequently, a slow death occurs, while the person suffers greatly and begins to have convulsions. If used in small quantities, strychnine is an excellent remedy for treating paralysis. Another useful property is that this substance speeds up metabolism.

Tetrodotoxin

This poison is found in a Japanese fish called fugu. Its content has also been noted in the caviar and skin of animals that live in water in tropical zone, and its presence has also been recorded in the eggs of the Californian newt. Doctors are not always able to cure a person after ingesting this poison, and the mortality rate is high. However, most people still prefer to try this delicacy - fugu dishes. But even the most experienced chef is not immune to the fact that the fish he cooks will poison his visitors.

V-Ex

This poison is used by the military as a chemical weapon. It paralyzes the human body and also causes nervous breakdown. If a person inhales its vapors, or the substance gets on the skin, then painful death occurs in less than an hour.

Ricin

Obtained from plants. Its grains are very dangerous; if they enter the respiratory tract, they endanger human life. He dies if this substance enters the blood. Very powerful, stronger than even cyanide, and only due to technical problems it was not possible to use it as a chemical weapon of mass destruction. But still, this poison is used by the military and terrorists.

Botulism toxin

Produced bacterial cells Clostridium botulinum, which are very dangerous to human health and life. When exposed to them, the body develops botulism. This poison is widely used in medicine: it is small quantities added to medical supplies and also he received wide application during operations in which Botox is used. Perhaps botulinum toxin is the most powerful poison for humans.

The poisons described in the article have a detrimental effect on the body, causing death in most cases. And if the victim is able to be saved from intoxication with these substances, then for the rest of his life he will experience various consequences and health problems.

Immense physical strength powerful fangs and razor-sharp teeth are not the only weapons used in the animal kingdom. Thousands of animals use highly toxic poisons for attack or defense.

We present to your attention the ten most poisonous creatures in the world.

(Total 14 photos)

1. Box jellyfish

Main prize Our top spot goes to the Box Jellyfish (Chironex fleckeri), which received this name because of its cubic shape. Over the past 60 years, this handsome man has claimed about 6 thousand lives. Its venom is considered the deadliest in the world, with toxins affecting the heart, nervous system and skin cells.

And, even worse, all this is accompanied by such hellish pain that the victims go into a state of shock and either drown or die from cardiac arrest. If you immediately treat the wound with vinegar or a solution of acetic acid, the victim has a chance, but, as a rule, vinegar cannot be found in water 😉

Box jellyfish can be found in sea waters Asia and Australia.

2. King Cobra(Ophiophagus hannah)

The king cobra (Ophiophagus hannah) is the longest poisonous snake in the world, reaching 5.6 meters in length. Ophiophagus literally translates to "snake eater" as it eats other snakes. A single bite from this deadly snake can easily kill a person. It can kill even an adult Asian elephant within 3 hours if the animal is bitten in a vulnerable area such as the trunk.

Among the representatives of snakes there are also more poisonous ones than the King Cobra, but it is capable of releasing much more poison than others. For example, 5 times more than the Black Mamba.
The king cobra is widespread in the dense mountain forests of the South and Southeast Asia.

3. Scorpio Leius quincestriatus

Contrary to popular belief, most scorpions are relatively safe for humans, since the stings only cause local effects (pain, anemia, swelling). However, Leiruses are very dangerous look scorpions because their venom is a powerful cocktail of neurotoxins that causes intense and unbearable pain, followed by fever, followed by coma, convulsions, paralysis and death.
Leiruses are common in North Africa and in the Middle East.

4. Taipan or Fierce Snake (Oxyuranus microlepidotus)

Just one taipan bite contains enough venom to kill 100 adult humans or an army of 250,000 mice. Its extremely neurotoxic venom is at least 200-400 times more poisonous than that of a common cobra. In just 45 minutes after a bite, an adult can die. But fortunately, there is an antidote, and besides, this snake is very timid and immediately crawls away at the slightest danger.
Lives in Australia.

5. Tree frogs or Poisonous frogs

If you ever manage to visit the rain forests of Central and South America, never touch the little ones beautiful frogs- they can be extremely poisonous. For example, the size of the Golden Dart frog is only 5 cm, and the poison in it is enough to kill 10 adults.
In the old days, local tribes used the poison of these frogs to lubricate the tips of their arrows.

6. Blue Ringed Octopus (Australian Octopus)

The Blue Ringed Octopus is a small, golf ball-sized, but extremely poisonous creature that lives in coastal waters around Australia and a little further north towards Japan. The blue-ringed octopus is usually light in color, with dark brown bands along its eight legs and body, with blue circles, added on top of these dark brown groups. When an octopus is disturbed or taken out of the water, it darkens and the rings become shiny and electric blue, and it is this color change that gives the animal its name.

Its poison is strong enough to kill a person. In fact, the octopus carries enough venom to kill 26 adults within a couple of minutes, and there is no antidote. If measures are not taken and treatment is not started, then the person begins to feel numbness, difficulty speaking, seeing, breathing problems arise, then complete paralysis and death occurs due to cardiac arrest and lack of oxygen.

7. Brazilian Wandering Spider (Phoneutria) or banana spider

This abomination was included in the Guinness Book of Records in 2007 for being guilty of the greatest number human deaths caused by spider bites. What is important is that these spiders are dangerous not only for their poison, but also for their behavior: they do not sit still and do not weave webs, they wander the earth, hiding in buildings, clothes, shoes, cars, anywhere; which significantly increases the risk of unexpectedly meeting them and being bitten.

8. Ball Fish or Puffer

Ball fish is the second most poisonous vertebrate animal on earth (the first is the Golden Dart frog from point 5). The meat of some subspecies, for example Fugu, is a delicacy in Japan and Korea, but the problem is that the surface of the fish and certain of its organs are very poisonous. The venom of fugu causes paralysis, resulting in suffocation and death from lack of oxygen.
Therefore, only licensed chefs are allowed to cook such fish in Japan.

9. Marbled Cone Snail

The marbled cone snail looks beautiful and very cute, but it can be just as deadly as any other animal on this list. A drop of its poison can kill 20 people. Signs of a bite: severe pain, swelling, numbness, and in serious cases, paralysis and respiratory failure. There is no antidote.

However, over the entire period, about 30 cases of human deaths from the poison of this snail have been recorded, which is not very much compared to other representatives of our list.

10. Stone fish

The stonefish may never win a beauty contest, but it will definitely win the "Most Beautiful" award. poisonous fish" The poison causes such unbearable pain that in search of salvation from suffering, victims wish to amputate the affected area. It is believed that the bite of a stone fish provokes severe pain, known to man. The pain is accompanied by shock, paralysis, and tissue death.

If you don't get an ambulance medical care, the outcome can be fatal.

Stonefish store their toxins in hideous dorsal ridges, which are designed to protect them from predators.
It is widespread in the tropical waters of the Pacific and Indian Oceans, from the Red Sea to the Great Barrier Reef.

Any type of poison is dangerous for humans: chemical, food or natural. There are hundreds of poisons that lead to death, and they are used for the purpose of murder, during war or terrorist acts, as a means of genocide against other peoples. Regardless of whether the poison is natural or obtained in a laboratory by chemical synthesis, it is capable of killing a person, and most often it is painful.

The most dangerous poisons

Since ancient times, poisons have served as killing weapons, antidotes, and, in small doses, medicine. We are surrounded toxic substances: they are found in blood, household items, drinking water. Even medicine taken not according to instructions or without a doctor's prescription can become poisonous. It causes irreversible changes in the body, which leads to poisoning and death.

Here are the most dangerous and deadly poisons:

Cyanide. Acts on the nervous and cardiac systems. It blocks the flow of oxygen to cells, paralyzing blood flow. Death occurs very quickly, in one minute. The most deadly cyanide poison is considered to be hydrogen (hydrocyanic acid with the smell of bitter almonds). It was used as a chemical weapon during wars and was subsequently phased out. Today it is used as the fastest method of murder or suicide.
Sarin. They are considered weapons of mass destruction and are used during wars or terrorist acts. It is a nerve gas that causes asphyxiation. Sarin can kill a person quickly; it will take an excruciating 60 seconds.
Mercury. It's toxic liquid metal, which is contained in a home thermometer. Even if it gets on the skin, mercury causes irritation. The most dangerous thing is inhaling its vapors. The person experiences blurred vision, memory loss, possible changes in the brain and kidney failure. The result is damage to the central nervous system and death occurs when a significant amount of vapor is inhaled.
Vi-Ex (VX). Nerve gas is considered a weapon of mass destruction around the world. Previously it was used as a pesticide. Contact of just a drop on the skin can cause death. More often it affects the respiratory system (inhalation). Signs of poisoning are similar to the flu, possible respiratory failure and paralysis.
Arsenic. For a long time, the words: arsenic and poison were inseparable. It is associated with murder for political purposes, as the symptoms of poisoning are similar to those of cholera. The properties of this metal are similar to mercury and lead. The disease manifests itself in the form of abdominal pain, seizures, coma and fatal outcome. In small concentrations it causes diseases such as cancer, diabetes, and heart disease.

For a long time active poisons lead to death not immediately, but after a long period of time. They are convenient to use, since it is difficult to suspect the death of a person who used this poison to kill for his own purposes.

An interesting fact from history. At one of the feasts, the Pontic king Mithridates was poisoned. The son, who sat on the throne, began to take small doses of poisons from his youth so that the body would gradually get used to them. When in fact he wanted to take his own life with poison, it did not work. He asked the guard to kill him with a sword.

Poisons of natural origin

Since ancient times, people have used it for hunting, war or food. natural poisons. Swords and arrows were stuffed with poison from snakes, insects or plant poisons. African tribes used substances that acted on the heart, in America they more often used paralyzing substances, and in Asia they used compounds that caused suffocation.

One of the most poisonous inhabitants the seas are gastropods family of cones. They shoot their prey with their harpoon-like teeth. Some release a mixture of toxins into the water, rendering the victim immobile. Toxins are similar in composition to the hormone insulin, which regulates blood sugar levels. When the fish receives hypoglycemic shock, it stops moving.

It is impossible to list all toxic substances; there are a huge number of them in nature. Let's name just a few poisons that are deadly to humans:

Tetrodotoxin. I natural origin, isolated from fugu fish. This is poison for humans, because specially trained chefs can cook fish correctly. Its meat is a Japanese delicacy. If prepared incorrectly, the oral cavity is paralyzed, the swallowing process is disrupted, and problems with speech and coordination of movement arise. Death occurs 6 hours after prolonged convulsions.
Botulism toxin. Refers to the most deadly poisons on the ground. A test tube with botulinum toxin can destroy many people, affecting the central nervous system. The mortality rate is 50%; the rest experience complications that require long-term recovery. It is volatile and easily accessible, and therefore dangerous. Although it is used as an injection for cosmetic purposes, as well as in the treatment of migraines.
Strychnine. Refers to poisons natural origin, found in a number of Asian trees. It can also be produced artificially. Usually used to poison small animals. Its action causes muscle contraction, nausea, convulsions, and suffocation. Death occurs within half an hour.
Anthrax. This is a disease caused by anthrax bacteria. The poison spreads through spores released into the air. Inhaling them is enough to become infected. There was a sensational story when anthrax spores were spread in letters. Panic arose, for which there were serious reasons. Once infected, a person experiences a cold, then breathing becomes impaired and stops. The deadly bacteria kills in 90% of cases within a week.
Amatoxin. Poison isolated from poisonous mushrooms. Once in the bloodstream, it affects the liver and kidneys. The person falls into a coma and dies from kidney or liver failure as the cells in these organs die within a few days. Amatoxin can also affect cardiac activity. The antidote is penicillin, which must be taken in fairly large doses.
Ricin. It is obtained from the castor beans of the castor bean plant. It has a lethal effect because it blocks the formation of protein in the body. Capable of killing when inhaled, so it is very convenient for sending in a letter, such cases have occurred. One pinch is enough to kill an entire organism. I use it in wars as a chemical weapon.

In the USA, there are grasshopper hamsters that love to hunt poisonous scorpions. Rodents have special cells, and after a bite they do not feel pain at all. Most likely, this ability arose due to a mutation that made scorpions a food source for hamsters.

How to determine a lethal dose of poison

To predict poisoning, you need to know the lethal dose of each poison. There is a table lethal doses for each substance, but it is very conditional, since every organism is individual. For some, this dose will be truly fatal, while others will survive with serious complications. Therefore, the dose numbers are approximate.

You should not try unknown berries in the forest or chew the leaves of a plant that is unfamiliar to you. This can be dangerous, as nature is rich in toxic compounds.

The effect of the poison can be affected by:

presence of individual characteristics;
pathology of organs or their functions, which reduces the body’s resistance to the action of a toxic substance;
vomiting, which can reduce the amount of poison ingested;
endurance of the body as a result of physical activity.

If you feel signs of poisoning, call an ambulance immediately. And in the case where the poisonous substance is known, it is possible to use antidotes that will reduce the effects of the poison and save from death. Be vigilant and take care of yourself!
