Arguing about poisons, it is impossible not to mention the famousParacelsus's phrase "everything is poison, everything is medicine." Indeed, even the usual product in excessive amounts can adversely affect the body. But there are substances that can also have a toxic effect in an insignificant dose. To determine their toxicity introduced the concept of "MLD". This is the minimum lethal dose, capable of causing death of a person weighing 70 kg. According to this concept, you can determine the strongest poison.
Since poisons, by their origin, are organic and inorganic, then comparing them among themselves in strength would be wrong. In each of these groups there are the most toxic representatives.
To organic poisons are all those thatare isolated by animals, plants or bacteria. By the strength of the action they surpass the inorganic and often do not have antidotes. One must be extremely cautious in those areas where the possibility of collision with sources of organic poisons is inevitable. To date, the list of leaders that emit strong poison, are:
- Pale toadstool is the most dangerous fungus of the genusfly agarics. For severe poisoning, it is enough to eat ¼ mushroom. The insidiousness of its toxins lies in the fact that poisoning does not appear immediately, but at this time there is irreparable destruction of the body, often leading to death.
- Kleshchevina - a plant from the family of euphorbia,cultivated as medicinal in the countries of Asia and Africa. Seeds contain a toxic substance, even in small doses dissolving erythrocytes. Survivors after poisoning do not restore their former health, since the poison irreversibly destroys the proteins of the tissues.
- Botulinum toxin is produced by bacteriaClostridium botulinum. The most dangerous toxin has no taste, color, odor and multiplies in canned foods. Causes death from paralysis of the respiratory and cardiac system.
Many believe that the strongest poison isroyal cobra, living in the forests of Southeast Asia. Usually the amount of poison in one bite is twice the death dose. 15 minutes after the attack of the cobra, paralysis of the respiratory muscles and respiratory arrest occurs.
Toxicologists and those who are familiar with marineinhabitants know that the strongest poison is at the blue-ringed octopus, the inhabitant of the Australian waters. Its toxins outweigh the strength of the cobra venom and cause death by a bite within a minute. In the salivary glands of this octopus contains just two toxins, acting on the nervous and muscular system. Death occurs as a result of paralysis of the respiratory muscles.
A similar poison is possessed by a fish-dog, living inthe seas of Southeast Asia. In spite of toxicity, dishes are prepared from it. When fish are improperly processed, the poison of nerve agent enters the human body, leads to convulsions and then to death.
Inorganic poisons are metal salts, alkalis, acids and their derivatives. Poisoning them is weaker, moreover, the most powerful poisons of inorganic origin are antidotes.
Pesticide parathion by inhalation and even ingestionon the skin causes severe poisoning, leading to excessive stimulation of the nervous system. Symptoms - copious flow and salivation, headache, vomiting, lacrimation.
Carbon tetrachloride is a corrosive liquid used as a cleaner. When inhaled, it affects the heart, kidneys and liver.
Cyanide potassium is the strongest poison in its group. When it enters the body, the cells stop absorbing oxygen, and interstitial hypoxia leads to death.
