Which poison to choose. Deadly substances. Most poisonous turtle: Bissa

There are a lot of poisons in the world, some of them act for a long time, others cause instant poisoning. When exposed to the body, each toxic substance causes specific symptoms, the most common of which should be known to every person.

Plant and chemical poisons are very dangerous not only for health, but also for life. Today, there are hundreds of types of potent substances, some of which are used far from good intentions - genocide, terrorism, etc. However, our ancestors, even with the help of the most powerful poison, treated many ailments. One way or another, experts are actively studying this issue today.

The toxicity of toxic substances from the group is caused by an immediate effect on the respiratory properties of cells, which aggravates its work. The work of cells stops, the internal organs begin to collapse. This leads a person to a very difficult condition, often ending in death. In fact, cyanide is a derivative of hydrocyanic acid.

It looks like a snow-white powder of small crystals. It dissolves quickly in water and is very unstable. Such a poison, in addition to laboratory methods, can be obtained from certain plants (fruit pits, almonds, etc.). However, poisoning is caused by a significant accumulation of a substance in the body.

Potassium cyanide is often used in industry:

  • production of paper, plastics and some types of fabrics;
  • in reagents for developing photographs;
  • in the metal industry, metal alloys are cleaned of impurities with the help of cyanide;
  • in granaries, products based on it protect products from rodents.

It is a fast-acting poison that can paralyze within minutes. The lethal dosage is only 0.1 mg / l. The person dies within one hour. First he loses consciousness, then his breathing and heart stop. Therefore, it is considered the fastest poison for humans.

Anthrax spores

This chemical compound provokes a very dangerous infection, which often ends in death. The disease is most susceptible to people who interact with farm animals. Spores are highly resistant and can be stored in the soil for a long time, so they are among the most dangerous poisons.

This terrible disease has been killing people for centuries. Only in the nineteenth century did the scientist Louis Pasteur succeed in making a vaccine. The specialist studied the resistance of animals to the effects of poisons by introducing a weakened strain of the virus into their bodies. A few years ago, American scientists developed a more effective vaccine.

Anthrax spores feel great in the secretions of an infected individual, getting through them into the soil and water. So they are carried over great distances. In African states, bloodsucking insects can become carriers of poison. The incubation period lasts from several hours to a week. The poison damages blood vessels, leads to swelling, loss of sensation and inflammation. Boils form on the skin, which develop into carbuncles. After some time, other very unpleasant symptoms may appear, from diarrhea to diarrhea. Often the patient is waiting for death.

The danger of sarin

Many Russians are familiar with this substance from school desks and life safety lessons. It is known to be one of the most powerful poisons in the world. Since the end of the last century, it has been used to create WMD (weapons of mass destruction). Sarin was discovered by one of the German chemical companies. At first, the substance was used only by the military.

Sarin is a highly volatile, odorless liquid. Therefore, patients begin to think about poisoning only after the onset of symptoms.

Intoxication is possible in several ways:

  • when poison enters the oral cavity;
  • through contact with the skin;
  • through inhalation of fumes (gas).

The organic poison damages the nerve endings, making it impossible for the proteins to keep them going. The mild stage of poisoning is accompanied by general weakness and shortness of breath. Medium - the pupils narrow, the head starts to hurt, tearing, nausea, trembling in the arms and legs appear.

If a person is not given first aid, then death is inevitable. The severe stage has similar symptoms, but they are more pronounced. Vomiting appears, involuntary excretion of urine and feces, headache intensifies. A few minutes later, the person loses consciousness and quickly dies.

Amatoxin is a strong natural poison

This is the strongest of the entire list of natural poisons on planet Earth. Experts have proven that amatoxin is much more dangerous than any snake venom. It is contained in the composition of pale grebes. Once in the human body, the toxin affects the liver and kidneys, after which all cells die.

Amatoxin is extremely insidious: manifestations are observed only after ten to twelve hours. In this case, it is already too late to wash the stomach, so you must definitely call a medical team. In the early stages, the patient may be helped by Cephalosporin or activated charcoal. The most severe cases of poisoning with this biological poison require a liver transplant.

Strychnine and its scope

It is a plant toxin that is often used to kill mice, rats, and other rodent pests. Get it in the laboratory from the seeds of chilibukha (an African plant). Such a poison is often mentioned in detective stories, where characters die from it.

It is used in the creation of some drugs that are prescribed in exceptional cases. Indications for the use of such drugs are neurological diseases, impotence, loss of appetite, alcoholism, etc.

Liquid metal - mercury

This substance is mentioned in treatises of 400 BC. But archaeologists also talk about more ancient traces. Mercury is often used in industry, art, medicine and other fields. Mercury vapor is highly toxic. Intoxication can be both cumulative and instant. First, the central nervous system is affected, and then other systems and organs.

The first signs of poisoning are trembling of the eyelids and fingers. After some time, there are problems with the stomach, vomiting, deterioration of sleep and memory. If poisoning with mercury vapor occurs, then at first there is damage to the respiratory system. Late or incorrect medical care can lead to death.

Often people encounter this liquid metal from a thermometer when it is broken. However, not everyone knows what to do in such a situation. First you need to collect all the mercury balls and fragments. This should be done with protective rubber gloves. The rest of the thermometer must be placed in an airtight container.

After all this, the room must be carefully treated with a solution of potassium permanganate of a strong concentration, and all existing surfaces should be wiped with a rag. After a day, the room should be well ventilated.


Poison of any origin, chemical, food or natural, has always been a subject of interest from the media, chemical safety and popular writers. Mankind knows hundreds of deadly poisons, many of which have been practically used as a means of murder, genocide and acts of terrorism. Some of them are presented in our review.


The well-known cyanide is a deadly poison that affects the central nervous system and the heart. Even a small dose, getting into the blood, binds iron molecules and blocks the supply of oxygen to vital organs, resulting in death in a matter of minutes. There are different forms of cyanide, such as hydrogen cyanide, which is considered the most poisonous. This gas kills a person in about 10 minutes. The gas was used during the First World War as a chemical weapon and was banned by the Geneva Convention. Today, cyanide is used as a means of murder, suicide, and in the plots of books.


This is the protagonist of the events of September 2011, when reports that people in envelopes received anthrax spores appeared in the news almost every day. As a result, five people died and 17 suffered from the effects of the poison, which caused panic among US citizens. This fear is understandable, as anthrax spores are easily airborne. After infection, numbness of the respiratory organs occurs and the person begins to suffocate. Out of 10 people, 9 die a week after infection.

Sarin is viewed as a mass murder agent that causes death by asphyxia in 60 seconds. A minute of terrible torment and the person dies. Since 1993, this substance has been banned from production, but despite this, in 1995, a massive terrorist attack was carried out in Japan on the subway, as well as in Iraq and Syria, as a result of which 330 to 1800 people died.


Amatoxin is a substance found in the world's deadliest mushrooms. When it enters the bloodstream, it affects the cells of the kidneys and liver, as a result, the organs fail after a few days. Amatoxin also affects the heart. If you do not enter a large dose of penicillin, then the person may fall into a coma or die from heart and liver failure.


Strychnine has been used as a pesticide to kill pests, but it can also kill humans. It was discovered in Asia, it was contained in special varieties of trees, but it can also be obtained in the laboratory (whoever managed to do this received a Nobel Prize). Strychnine can enter the body in different ways: injection, inhalation and absorption. After entering the body, muscle convulsions and spasms begin, leading to asphyxia. After an injection, a person dies in half an hour.

Even at school, everyone was warned to be careful with a thermometer. And this is not just because, but because of the heavy metal called mercury. It is an incredibly toxic metal that enters the body either by inhalation or skin contact. If it comes into contact with the skin, mercury causes itching, burning, and the skin may even peel off. Mercury can cause memory loss, vision loss, kidney failure, and destruction of brain cells. The result is death.


An infamous poison found in puffer fish, popular with sushi connoisseurs who are willing to pay a hefty price in the hope that the fish is cooked right. The first symptoms appear as early as 30 minutes after eating poisonous fish. At first, a person feels like his mouth is paralyzed, it becomes difficult to swallow. Soon there is a violation of coordination of movements and speech. Attacks, convulsions begin, as a result, a person can fall into a coma and die. Death occurs after about 6 hours, but cases of death after 17 minutes are known. This poison is considered one of the deadliest on earth.

Ricin is another poison that has become popular, along with anthrax, due to its mailing. The actress who starred in the movie "Walking Dead" was convicted of just such a crime. Ricin has been found in the seeds of the castor bean. Ricin is an incredibly lethal poison, it binds protein in the body, resulting in death. It was considered as a chemical weapon by the US military and members of al-Qaeda.


The most dangerous nerve gas on the planet, a former pesticide, has become an excellent target for military forces around the world, despite the ban on the use of weapons of mass destruction. There is no other use for gas, except in times of war. The gas is so poisonous that one drop of it on the skin kills a person. When inhaled, the first symptoms of poisoning are similar to the onset of the flu, then respiratory paralysis occurs, which leads to death.


It is the deadliest poison on earth. A cup of the toxin can kill hundreds of thousands of people by causing the disease botulism, a disease that affects the central nervous system. Surprisingly, this poison has important practical uses, from Botox injections to treating migraines. It is known that some patients after procedures with the use of botulinum toxin died. Of those affected by this poison, 50% die without medical attention, and those who survive suffer serious complications for many years. Due to its unstable state and easy availability in nature, botulinum toxin is the most deadly poison in the world. However, the cosmetics industry often uses

Many inquisitive people, most likely, wondered which creature is the most poisonous on earth. Interestingly, for a long time it was believed that these were snakes and spiders. But research scientists have painted us a different picture. And now we will consider what, in their opinion, is the most poisonous creature in the world. The top 10 suggested below may surprise some nature lovers.

First place - box jellyfish

The box jellyfish has another name - "sea wasp", because after it stings, the victim experiences unbearable pain. Many will agree that this is the most poisonous creature in the world. The Guinness Book of Records also shares this view. This jellyfish is reported to kill a human in a short time, 1 to 3 minutes. But not only this makes her a terrible enemy. The deadly tentacles can simultaneously hit up to 60 people if they are within a radius of 8 meters. Extremely fast and irreversible. Toxins attack the heart muscle and nervous system, causing hellish pain. If the touch of the tentacles was superficial, severe burns remain.

There is an antidote. If you immediately treat the bite with a solution of acetic acid, there is a chance to survive, but this usually fails. Jellyfish victims drowned because they went into shock or died from cardiac arrest. Every year, about 6,000 vacationers die from the poison of the sea wasp. Only a few people survived the bite, and they even felt pain a few weeks later.

This most poisonous creature in the world (photo shown above) lives in the waters of Northern Australia, but sometimes the "wasp" is found near South Asia. At the same time, it is quite difficult to see an object in the water, since the jellyfish merges. But there is a creature that is not afraid of box jellyfish - this is a sea turtle.

Second place - king cobra

Some are ready to argue that the most poisonous creature on earth is, after all, there are snakes with more toxic poison. But in the Guinness book, she takes an honorable second place due to how much poison she spits out at a time. It reaches 4 meters in length, but since these cobras grow all their lives (and they can live 30 years), some individuals reach 6 meters.

The amount of venom squirted depends on the size of its prey, but the dose is usually slightly more than what is needed to kill.

A case has been recorded when an Indian elephant died within three hours, as it was struck by a king cobra. With a large amount of poison, a person dies in 15 minutes from the onset of paralysis and respiratory arrest. But even more terrible is the fact that the cobra is able to rise to a third of its height. If its length is 5 meters, then it is extended by 1.6 meters. But it can please the fact that they do not attack first (if not disturbed).

Its range is the forests of South Asia, but since there is active logging, the cobras are forced to move closer to the human habitat.

Third place - scorpion Leyurus

Another most poisonous creature in the world is the Leyurus scorpion, which is found in North Africa, as well as in the Middle East. Although these scorpions are not aggressive and will not attack unless they sense danger, their venom can kill a person. Although there are many dangerous scorpions in nature, this subspecies is the most deadly. Leiruses carry a "cocktail" of neuroleptics, if it gets into the bloodstream, the victim will die.

Initially, the stung place swells and the person feels incredible pain, after which comes a fever that develops into convulsions. The end result is paralysis and death. Interestingly, before committing a deadly attack, the "baby" begins to move, as if dancing, and this warns of its intention.

Fourth place - taipan

Among the world's creature is the taipan. The danger lies in the huge amount of poison that is released during the attack. This land snake is capable of fatally injuring 100 people. Its poisonous mixture is about 400 times more toxic than the venom of an ordinary cobra. After being bitten by an adult, death occurs in an average of 45 minutes. About 90% of attacks for a person are fatal, even though the antidote exists and many people know about it.

This snake is very aggressive and can attack suddenly at a speed of 4 m/sec. But at the same time, taipans are quite shy and, sensing danger, can crawl away. This creature lives in Australia on arid plains, but often creeps up to the water.

Fifth place - dart frog

Some believe that the most poisonous creature on the planet is the poison dart frog because of its deceptive appearance. She looks very attractive and completely defenseless, but this is a hoax. Her skin of a bright saturated color is covered with poison (batrachotoxin), which, when it enters a person through microscopic damage, freely enters the body. A gram of its poison can kill 10 people. This toxic substance consists of hundreds of components that have a nerve-paralytic effect. The scary thing is that the antidote has not yet been created and it is practically impossible to escape from the effects of the poison that has got on the skin.

Scientists know 179 species of these "deceptive" creatures. They are divided into nocturnal (harmless) and daytime (toxic).

These poisonous amphibians can grow up to 8 cm. But the smallest ones (1.5 - 2.5 cm) are considered the most poisonous. They can be found in Central and South America in the rainforests. They are also called "dart frogs" because in the past the natives used their venom to grease their arrowheads.

It is noteworthy that these creatures do not produce poison on their own, they get it from poisonous insects.

Sixth place - blue-ringed octopus

This ring-shaped octopus has also received a place in the ranking of "the most poisonous creature on the planet." Although this creature is small in size, no larger than a baseball (weight 100 gr.), It has a toxic and dangerous poison. One portion, which the octopus excretes at a time, is enough to poison 25 people. Death can come within minutes. During this time, the victim will begin to experience problems with vision and speech, and numbness will occur. Then it becomes difficult for the person to breathe. The next fatal symptom is complete paralysis. Lack of oxygen and cardiac arrest will lead to death. It is impossible to neutralize the action of the poison, since the antidote has not been created.

This "cute" creature lives near the Australian and South Asian coasts. It is widely distributed and prefers shallow depths. But fortunately, he leads a night life, so it is not easy to stumble upon him. In addition, the creature has a calm disposition and attacks only if it is "pissed off". Its ability to change color sometimes leads to incidents, because the octopus is confused with other harmless coastal inhabitants.

Seventh place - wandering spider

Another most venomous creature in the world that is feared without even knowing its toxicity is the wandering spider. He has a rather aggressive disposition. In addition, it is terrifying in that it is the largest of all spiders in the world.

It can be found in Central and South America in the tropical region, especially on banana plantations, but sometimes this creature climbs into houses. He does not weave webs and travels on his own to find food, which is what makes him very dangerous. He can stop to rest in a residential building, hide in a car or clothes. As a result, the percentage of cases of spider attacks is very high. This arthropod is not shy and is immediately ready to attack, so if you had to meet him, do not try to scare him, because he will not retreat, you better run.

Spider venom causes lung spasm and loss of muscle control. The person may become suffocated. Also, toxins affect the lymphatic system and cardiac arrest can occur. The still alive victim feels how the body gradually stiffens. The poison is 20 times more toxic than the "black widow".

Interestingly, in the Guinness book, this is the most poisonous creature in the world among spiders. It is also noted that more deaths occurred through his fault than from other arthropods.

Eighth place - fugu

Of the vertebrates, this is the most poisonous creature in the world. Many people know him by the name of the ball fish. The entire surface of the fish is considered poisonous, and some puffer organs are also dangerous. A set of toxins causes paralysis and suffocation in the affected person, which in turn leads to death from insufficient oxygen. But despite this, in Korea and Japan, this fish is a first-class delicacy. Given its dangerous composition, only those professionals who have received a special license can cook fugu.

Ninth place - cone snail

Some, when they see this marble snail, do not understand that it belongs to dangerous creatures, since its appearance is very attractive. But you can’t judge by appearance, because she is just as dangerous as the rest of the representatives of this list. Just one drop of poison can kill 20 people. After the snail stings, the victim begins to experience excruciating pain, then numbness sets in and the bite site becomes inflamed. The next stage is paralysis and suffocation. There is no cure for such poisoning.

But if you look at the statistics, only 30 deaths were recorded due to the fault of this snail.

Tenth place - stone fish

This unsightly creature occupies the last place in the ranking of "the most poisonous creature in the world." The bite of this underwater inhabitant provokes the most acute pain known to man. The sensations are so strong that in search of relief, the victim is ready for suicide or amputation of the bitten place. Such pain causes shock, then paralysis inevitably sets in, and the tissues at the site of the lesion begin to die, without medical assistance a person is threatened with death.

This dangerous "beast" is found in the waters of the Red Sea and in the tropical regions of the Indian and Pacific Oceans.

Omega is a highly toxic substance that is part of the hemlock. Just 100 milligrams of it (8 leaves) will be enough to kill a person. Principle of operation: all systems of the body gradually fail, except for the brain. In total, you, being in your right mind, begin to slowly and painfully die until you suffocate.

The most popular hemlock was among the Greeks. Interesting fact: this plant caused the death of Socrates in 399 BC. The Greeks thus executed him for disrespect for the gods.

№9 - Aconite

This poison is obtained from the wrestler plant. It causes an arrhythmia that ends in suffocation. They say that even touching this plant without gloves can end in death. It is almost impossible to detect traces of poison in the body. The most famous case of application - Emperor Claudius poisoned his wife Agrippina by adding aconite to her mushroom dish.

No. 8 - Belladonna

In the Middle Ages, belladonna was used as a cosmetic for women (cheek blush). They even received special drops from the plant - to dilate the pupils (at that time it was considered fashionable). And you could also swallow the leaves of belladonna - one is just enough for a person to die. Berries are also not a miss: for death it is enough to eat only 10 pieces. From the latter in those days they made a special poisonous solution, which was used to lubricate arrowheads.

No. 7 - Dimethylmercury

This is the slowest and most insidious killer. This is because even 0.1 milliliters that accidentally get on your skin will be enough for a fatal outcome. The most high-profile case: in 1996, a chemistry teacher from Dartmouth College in New Hampshire dropped a drop of poison on her hand. Dimethylmercury burned through a latex glove, symptoms of poisoning appeared after 4 months. And 10 months later, the scientist died.

#6 - Tetrodotoxin

This poison is found in blue-ringed octopuses and pufferfish (fugu). Things are very bad with the first ones: octopuses deliberately attack their prey with tetrodotoxin, imperceptibly pricking it with special needles. Death occurs in a few minutes, but symptoms do not appear immediately - after paralysis sets in. The venom of one blue-ringed octopus is enough to kill 26 healthy men.

Fugu is easier: their poison is dangerous only when it is about to eat a fish. It all depends on the correctness of the preparation: if the cook is not mistaken, the tetrodoxin will all evaporate. And you will eat the dish without any consequences, except for the incredible adrenaline rush ...


Source: wikipedia.org

No. 5 - Polonium

Polonium is a radioactive poison for which there is no antidote. The substance is so dangerous that just 1 gram of it can kill 1.5 million people in a few months. The most sensational case of the use of polonium is the death of Alexander Litvinenko, an employee of the KGB-FSB. He died in 3 weeks, the reason - 200 grams of poison was found in his body.

No. 4 - Mercury

  1. elemental mercury - found in thermometers. Instant death occurs if it is breathed in;
  2. inorganic mercury - used in the manufacture of batteries. Deadly if swallowed;
  3. organic mercury. Sources are tuna and swordfish. It is recommended to eat them no more than 170 grams per month. Otherwise, organic mercury will begin to accumulate in the body.

The most famous use case is the poisoning of Amadeus Mozart. He was given mercury tablets to treat syphilis.

How to poison a person with poison is asked not only by potential attackers, but also by ordinary Internet users. Today, the pharmaceutical market offers consumers a variety of drugs, some of which are available for purchase without a prescription.

And there are also toxic substances that allow you to quickly eliminate an opponent or, conversely, provoke a chronic disease. Age-old knowledge and modern technologies become dangerous weapons in the hands of competent people.

Potassium cyanide is known to almost everyone; at the beginning of the 20th century, a dangerous powder was a common way to get rid of unwanted faces.

The poison belongs to the group of hydrocyanic acid derivatives and is highly soluble in water. Some sources point to the specific smell of this substance, however, not all people are able to feel it. Potassium cyanide causes poisoning if ingested, and it is also dangerous to inhale powder particles and solution vapors. The lethal dose of poison is only a few grams, but in most cases it depends on the weight and individual characteristics of the organism.

With the help of potassium cyanide, you can quickly poison a person. Death is affected by the way the substance enters the body, so when particles are inhaled, the action of the toxin manifests itself instantly, and when it enters the stomach, the poison begins to cause irreversible consequences after 15 minutes.

The victim goes through several stages of intoxication. At first, a sore throat is felt, then nausea and vomiting begin, and numbness of the pharynx is possible. Over time, general weakness increases, a feeling of fear arises, and the pulse slows down. Subsequently, signs such as convulsions and loss of consciousness are noted. As a rule, if a sufficient dose of poison is ingested, a person dies within 4 hours.

With the advent of new drugs on the pharmaceutical market, people are interested in how to poison a person with pills. The list of dangerous poisons, if used incorrectly, includes the following drugs:

  • sleeping pills "Phenazepam";
  • hellebore water;
  • drops "Corvalol".

The medicine "Phenazepam" is prescribed by doctors as a remedy for insomnia, panic attacks and stress. It refers to psychotropic drugs, and offenders use this drug in order to poison a person in a dream.

Like many other drugs, "Phenazepam" is incompatible with alcohol - this is what criminals use, since the joint use of these pills and alcoholic beverages leads to respiratory arrest and death. But it is not easy to get the described drug, since it is dispensed exclusively by medical prescription.

Hellebore water is freely sold in pharmacies and is used not only in traditional medicine, but also as a remedy for alcohol addiction. However, some cases of intentional intoxication are not taken into account, therefore such a remedy is suitable for those who want to poison a person without determining the poison.

Fatal outcome occurs when ingested 2 years. raw materials, hellebore water adversely affects the functioning of the heart and blood pressure. Thus, the supply of oxygen to the brain gradually decreases.

As a rule, alcohol accelerates the absorption of poison and signs of intoxication with hellebore water develop within 20 minutes after taking the remedy. Vomiting begins, and symptoms such as intense thirst, slow heart rate, and mental disorder are noted. Death occurs on average after 8 hours, such a medicine allows criminals to poison a person without determining the exact cause of death.

Drops of "Corvalol" can be purchased at any pharmacy, which makes them an affordable and effective medicine for poisoning. The lethal dose of the drug depends on the weight and age of the person, on average it is 150 drops.

Intoxication is characterized by prolonged sleep, lowering blood pressure and dilated pupils. The joint use of this drug with alcohol is especially dangerous, in which case tachycardia appears, the skin turns blue. Most likely, it will not work to poison a person slowly with the help of Corvalol drops, a fatal outcome occurs within a day, which is used by various asocial elements of society.
