Poisons symptoms. The most dangerous poison in the world. What are the poisons?

Any toxic substances, be they chemical or plant, pose a serious danger to the body. Science knows dozens and hundreds of the strongest poisons, many of which are used by man himself, and not for good deeds - this includes terrorism, genocide, and much more. But there were also times when poisons were considered medicines. One way or another, toxic substances are still undergoing active research in laboratories. What is the most powerful poison in the world?

Cyanide

Cyanides are a class of harmful, potent substances that are dangerous to humans. Their toxicity is explained by their immediate effect on the respiratory functions of cells, which, in turn, stops the work of the entire body. Cells stop functioning, organs fail. All this leads to a very serious condition, fraught with death. Cyanide itself is a derivative of hydrocyanic acid.

Externally, cyanide is a white powder with a crystalline structure. It is quite unstable and dissolves well in water. We are talking about the most famous type - potassium cyanide, and there is also sodium cyanide, which is also quite toxic. The poison is obtained not only in the laboratory, but also extracted from plants. It is important to know that some foods may contain this substance in small quantities. Almonds and fruit seeds are dangerous. But the poisoning is cumulative.

Cyanide is often used in industrial production - in particular, the production of paper, some fabrics, plastics, as well as in reagents for photo development. In metallurgy, cyanide is used to purify metals from impurities; and in grain storage facilities rodents are destroyed using means based on this poison. The lethal dose of the most dangerous poison in the world is 0.1 mg/l, and death occurs within an hour. If the quantity is greater, then in ten minutes. First, the person loses consciousness, then stops breathing, and then the heart stops.

This substance was first isolated by the German chemist Bunsen, and in 1845 methods of production on an industrial scale were developed.

Anthrax spores

These substances are the causative agents of an extremely dangerous infectious disease, most often ending in death. People who come into contact with livestock are at risk of contracting Bacillus Anthracis. Spores can be stored in the soil of a cattle burial ground for a very long time.

The disease has been killing people for centuries, especially during the Middle Ages. And only in the 19th century Louis Pasteur managed to create a vaccine against it. He studied the resistance of animals to poisons by injecting them with a weakened strain of ulcer, which resulted in the development of immunity. In 2010, US scientists created an even more effective vaccine against the disease.

Anthrax spores are found in all secretions of a sick animal, ending up with them in water and soil. Thus, they can spread hundreds of kilometers from the source of infection. In African countries, insects that drink blood can also become infected with poison. Incubation ranges from several hours to seven days. The poison causes irreparable damage to blood vessels, causing swelling, loss of sensitivity, and inflammation. Carbuncles begin to appear on the skin; It is especially dangerous if they occur on the face. Subsequently, a host of other unpleasant symptoms may occur, from diarrhea to bloody vomiting. Often the patient will die at the end.


The disease caused by anthrax spores develops extremely quickly and causes terrible external and internal damage.

Many residents of Russia remember this name from school life lessons. One of the most toxic substances on Earth since 1991 has been classified as a weapon of mass destruction. And it was discovered in 1938 by a chemical company in Germany and from the very beginning was intended for military purposes.

Under normal conditions, sarin is an odorless liquid that evaporates quickly. Since it cannot be smelled, poisoning can only be known when symptoms appear.

Moreover, poisoning occurs through inhalation of steam, and through contact with skin or entry into the oral cavity.

Sarin binds certain enzymes, in particular protein, as a result of which it can no longer support nerve fibers.

Mild poisoning results in shortness of breath and weakness. In moderate cases, constriction of the pupils, lacrimation, severe headache, nausea, and trembling of the limbs occurs. If timely assistance is not provided, death occurs in 100% of cases, but even if assistance is provided, every second poisoned person dies. Severe degree is characterized by the same symptoms as moderate, but they are more pronounced and progress faster. Vomiting occurs, spontaneous excretion of feces and urine occurs, and an incredible headache appears. A minute later the person faints, and five minutes later he dies from damage to the respiratory center.


Sarin was not used in World War II due to Hitler's prejudice against poisonous gases.

Amatoxin

This is the most powerful venom that is independently produced in nature, it is more powerful than the venom of any snake. It is mainly found in white toadstools and when ingested, it affects the kidneys and liver, and then gradually kills all cells over the course of several days.

The poison is very insidious: the first symptoms appear only after 12 hours, and sometimes up to a day. Of course, it’s already too late to do gastric lavage; you need to call an ambulance. Within two days, traces of amatoxin can be detected in a urine test. Activated charcoal and the drug cephalosporin can also help the patient, and in particularly difficult cases it is necessary to resort to a liver transplant. But even after recovery, the patient may suffer from heart, kidney and liver failure for a long time.


A large dose of penicillin is used as an antidote; if it is not introduced, then a person dies on average within a week

This is a poison of plant origin, most often used in baiting small rodents. It has been produced in the laboratory since 1818, extracting it from the seeds of the African chilibuha plant. Strychnine is mentioned in many detective novels, where characters die from exposure to this substance. One of the properties of strychnine is also played out: at the very beginning, it causes a sharp and powerful surge of strength by blocking some neurotransmitters.

The substance is used in the production of medicines, but drugs containing strychnine nitrate are prescribed only in the most extreme cases. Indirect indications for use may be neurological diseases in which nerve impulses are inhibited; poor appetite; impotence; severe forms of alcoholism that cannot be cured by other methods.

Symptoms of poisoning with this poison are similar to the primary symptoms of tetanus. These include difficulty breathing, chewing and swallowing, fear of light and convulsions.


A dose of 1 milligram per 1 kilogram of body weight is fatal.

The first information about mercury has reached us from the depths of time; it is mentioned in documents dating back to 350 BC, and archaeological excavations have also found more ancient traces. The metal was widely used and continues to be used in medicine, art, and industry. Its vapors are extremely toxic, and poisoning can be either immediate or cumulative. First of all, harm is done to the nervous system, and then to other systems of the body.

The initial symptoms of mercury poisoning are trembling of the fingers and eyelids, and later - of all parts of the body. Then there are problems with the gastrointestinal tract, insomnia, headache, vomiting, and memory impairment. In case of poisoning by vapors, rather than mercury compounds, damage to the respiratory tract is initially noticed. If exposure to the substance is not stopped promptly, it can be fatal.


The effects of mercury poisoning can be inherited

Most often, a person encounters mercury from a thermometer, especially if it breaks. But not everyone knows exactly how to act in this situation. First you need to quickly collect all the parts of the thermometer and the mercury balls. This must be done as carefully as possible, because the remaining particles can cause irreparable harm to residents, especially children and animals. This is done with rubber gloves. In hard-to-reach places, you can collect mercury using a syringe or patch. Place everything collected in a tightly closed container.

The next step is a thorough cleaning of the room, also done with gloves (already new) and a medical mask. A highly concentrated solution of potassium permanganate is suitable for processing. Wipe absolutely all surfaces in the house with this solution using a rag. Fill any gaps, cracks and other depressions with mortar. It is advisable to leave everything in this form for at least a day. For the next few days, ventilate the room daily.


You can call specialists who will make sure that there is no mercury or its vapor in the house if the thermometer breaks

Tetrodotoxin

The most effective defense mechanisms that nature has endowed living beings with are neurotoxins. These are substances that specifically damage the nervous system. Tetrodotoxin is perhaps the most dangerous and unusual of them. It is found in a variety of both terrestrial and aquatic animals. The substance tightly blocks the channels of nerve cells, which causes muscle paralysis.

The most common source of poisoning in Japan was eating fugu fish. It is surprising that today this fish is still used in cooking and is considered a delicacy - however, you need to know which parts to eat and in what season to catch the fish. Poisoning occurs extremely quickly, in some cases within six hours. It begins with a slight tingling of the lips and tongue, followed by vomiting and weakness, after which the patient falls into a coma. Effective emergency assistance measures have not yet been developed. Only artificial respiration can prolong life, because before death, breathing first stops, and only after a while does the heart stop beating.


Tetrodotoxin has been studied for many years, but not all details about it have yet been discovered.

The poisons described above have an extremely harmful effect on animal organisms, so extreme care must be taken when handling them. It is better if professionals do this.

Not only potential attackers, but also ordinary Internet users ask about how to poison a person with poison. Today, the pharmaceutical market offers consumers a variety of medications, some of which are available for purchase without a prescription.

There are also toxic substances that can 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, the dangerous powder was a common way to get rid of unwanted persons.

The poison belongs to the group of hydrocyanic acid derivatives and is highly soluble in water. Some sources indicate a specific smell of this substance, however, not all people are able to smell 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 body.

Potassium cyanide can quickly poison a person. Death is affected by the route of entry of the substance into the body, so when particles are inhaled, the effect 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 begins, and possible numbness of the throat. 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 arrival 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 medications:

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

The medicine "Phenazepam" is prescribed by doctors as a remedy against insomnia, panic attacks and stress. It refers to psychotropic medications, and offenders use this drug to poison a person in their sleep.

Like many other drugs, Phenazepam is incompatible with alcohol - this is what criminals take advantage of, since the combined use of these tablets and alcohol leads to respiratory arrest and death. But it is not easy to get the described drug, since it is sold only with a doctor’s prescription.

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

Lethal outcome occurs when ingested for 2 years. raw materials, hellebore water negatively affects heart function and blood pressure. Thus, the oxygen supply 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 product. Vomiting begins, and symptoms such as extreme thirst, slow heart rate, and mental disturbances are also noted. Death occurs on average after 8 hours; this medicine allows criminals to poison a person without determining the exact cause of death.

Corvalol drops 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, decreased blood pressure and dilated pupils. The combined use of this drug with alcohol is especially dangerous; in this case, tachycardia appears and the skin turns blue. Poisoning a person slowly using Corvalol drops will most likely not work; death occurs within 24 hours, which is taken advantage of by various asocial elements of society.

There are a sufficient number of natural and artificially produced poisons in the world. The effects of all toxic substances are different. Some can instantly take life, while others destroy the body gradually, forcing a person to suffer for a long time. There are potent substances that in small doses poison a person asymptomatically, but there are also the most dangerous poisons that cause severe pain, which even in small quantities can be fatal.

Chemical compounds and gases

Cyanide

Hydrocyanic acid salts are an extremely dangerous poison. Many lives have been taken using this potent substance. On the battlefield, they poisoned the enemy with cyanide, spraying poison that instantly killed soldiers, getting on the mucous membranes and affecting the respiratory system. Currently, cyanide is used in analytical chemistry, in the mining of gold and silver, in electrochemistry, and in organic synthesis.

One of the salts of hydrocyanic acid, the potassium salt, known as potassium cyanide, is a powerful inorganic poison. It looks like granulated sugar, and can easily be classified as an instant poison. Entering the human body through the gastrointestinal tract, death occurs instantly; only 1.7 mg per 1 kg of weight is enough. Potassium cyanide prevents oxygen from entering tissues and cells, resulting in death from oxygen starvation. Antidotes for this poison are compounds containing hydrocarbons, sulfur and ammonia. Glucose is considered the strongest anticyanide, so in case of poisoning, its solution is administered intravenously to the victim.

Apparently, in order to avoid prolonged death throes, this poison was chosen by some famous Nazis to commit suicide, since it acts instantly. According to one version, Adolf Hitler himself was among them.

The vapors of this poisonous element are extremely toxic and insidious, because they have no odor. Mercury affects the body through the lungs, kidneys, skin and mucous membranes. Soluble compounds of this substance are more dangerous than pure metal, but it tends to gradually evaporate and poison a person.

It is especially harmful for the population when mercury compounds enter a body of water. In the aquatic environment, the metal is converted into methylmercury, and then this powerful organic poison accumulates in the organisms of the inhabitants of the reservoir. If people use this water for domestic needs and go fishing in such places, then this is fraught with mass poisoning. Regular inhalation of mercury vapor is a slow-acting poison. Toxins accumulate in the body, which leads to nervous disorders, up to the onset of schizophrenia or complete insanity.

Exposure of a pregnant woman to mercury can lead to irreversible consequences, as it spreads quickly through the blood and easily penetrates the placenta. Even a seemingly harmless broken thermometer, which contains a small amount of this potent toxic substance, can provoke the development of defects in a child inside the womb.

Sarin

The extremely poisonous sarin gas, which was developed by two German scientists, kills a person in one minute. It was used as a chemical weapon in World War II and the Civil Wars, after which both the United States and the Soviet Union began producing sarin and stockpiling it in case of war. Following an experimental incident that resulted in death, production of this poison was discontinued. Nevertheless, Japanese terrorists managed to obtain this poison in the mid-nineties - the terrorist attack on the Tokyo subway, during which about 6,000 people were poisoned with sarin, received wide attention.

Sarin affects the body both through the skin and through the respiratory system, affecting the nervous system. Severe intoxication is observed due to ingestion of this substance by inhalation. This nerve gas kills a person quickly, but at the same time brings hellish torment. First of all, the gas affects the mucous membranes, a person begins to have a runny nose and blurred eyes, then vomiting and severe pain behind the sternum appear, and the last stage is death from suffocation.

Ingestion of this poison in large quantities is fatal. It is a white fine powder, which can be purchased even at a pharmacy, only with a prescription. With constant poisoning in small doses, arsenic can provoke the occurrence of diseases such as cancer and diabetes. This poison is often used in dentistry - arsenic is used to destroy the inflamed dental nerve.

Formaldehyde and phenols

Literally everyone has encountered these household poisons that are dangerous to humans.

Phenols are contained in varnishes and paints, without which no cosmetic repair can be done. Formaldehyde can be found in plastics, fiberboard and chipboard.

With prolonged inhalation of these potent toxic substances, breathing is impaired, various types of allergic reactions, dizziness and nausea appear. Constant contact with these poisons can result in malfunctions of the reproductive system, and with severe intoxication, a person can die from swelling of the larynx.

Poisons of plant and animal origin

Amatoxin

Amatoxin is a poison that affects the gastrointestinal tract. The source of poisoning is some types of mushrooms, for example, toadstool and white toadstool. Even in acute poisoning, amatoxin has a slow effect on an adult, which makes it possible to classify this potent substance as a delayed-action poison. In case of poisoning, severe vomiting, pain in the stomach and intestines, and continuous bloody diarrhea are observed. On the second day, the victim’s liver enlarges and the kidneys fail, after which coma and death occur.

A positive prognosis is observed with timely treatment. Despite the fact that amatoxin, like all slow-acting poisons, causes irreparable harm gradually, there have also been lightning deaths, mainly among children.

Batrachotoxin is a powerful poison that belongs to the alkaloid family. It is almost impossible to meet him in everyday life. It is secreted through the glands of leaf frogs. This substance, like other instant-acting poisons, instantly affects the nervous system, causes heart failure and leads to death.

Ricin

This plant poison is six times more toxic than the instant killer cyanide. One pinch is enough to kill an adult.

Ricin was actively used as a weapon in war; with its help, intelligence services got rid of individuals posing a threat to the state. They found out about it quite quickly, since lethal doses of this potent substance were deliberately sent to recipients along with letters.

Bacillus anthrax

This is the causative agent of an infectious disease that poses a huge danger to domestic animals and humans. Anthrax is very acute and, as a rule, the infected person dies. The incubation period lasts up to four days. Infection most often occurs through damaged areas of the skin, and less often through the respiratory tract.

With the pulmonary form of infection, the prognosis is unfavorable and mortality rates reach 95%. Most often, the bacillus is localized in certain areas of the skin, so anthrax is one of the most dangerous contact poisons, fatal to humans. With adequate and timely treatment, a person is on the path to recovery. The infection can affect the intestines and affect internal organs, leading to sepsis. Another severe form, which is cured only in very rare cases, is anthrax meningitis.

Despite the fact that mass infection with this poison in everyday life, fortunately, has not been observed for a long time, cases of this terrible disease are still being recorded in Russia.

The Sanitary and Epidemiological Service regularly conducts veterinary surveillance on the territory of pig farms and agricultural enterprises that keep cattle.

You should not assume that potent toxic substances are only the hard-to-reach poisons listed above. Any chemical in large quantities can be a deadly poison for humans in everyday life. This includes chlorine, which is used for disinfection, and various detergents, and even vinegar essence. To be wary of toxic substances, to take precautions when handling them and to hide them from children is the strict responsibility of every conscious adult.

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 a 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 all internal organs of a 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 was also noted in the caviar and skin of animals that live in water in the tropical zone, and its presence was also recorded in the caviar 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

It is produced by 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 added in small quantities to medications, and it is also widely used in 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.
