Top 5 deadliest Food Poisons on Earth

Zak Ben - Monday, August 04, 2014
To classify the toxicity of a poison often use the LD50. In this term indicates the "lethal Dose 50". Refers to a dose of substance, administered only once, that is capable of killing a 50% sample of Guinea Pigs. Today this parameter is no longer used, for ethical reasons and economical. The toxicologists, are increasingly aware of the limitations of LD50.

The administration of toxic substances experimented with LD50, cause severe symptoms that can lead to death. Wonder how highly toxic substances are also used in cosmetics, and notwithstanding the contraindications, the use is increasingly common. These are the five most poisonous toxins on Earth.

The Top 5 deadliest Food Poisons on Earth 

5. Mercury

The harmful effects of mercury are perhaps the most famous. This compound occurs in organic and inorganic form. The organic form of mercury is more toxic than the inorganic form. Mercury is used as a mould in paints and used by dentists as dental amalgam. In the context of food, grains and fish, most foods are exposed to mercury. Between the effects of mercury toxicity are tremors, forms of hallucinations, kidney damage, damage to the cerebral cortex and the cerebellum, vision loss, hearing loss and death. There are several types of mercury, the lethal dose of the substance range from 1 mg to 100 mg.

4. Polonium 210

Polonium is a radioactive metalloid, which lies in the uranium. It was discovered in the late 19th century by Marie Curie, then used for the creation of the atomic bomb during the Manhattan project. Polonium 210 is highly radioactive, to manipulate it requires appropriate equipment and places. Inhalation of just one milligram can be lethal. Even small amounts of Polonium can damage irreversibly the tissues and organs of the body. Once the venom has entered the bloodstream, it is difficult to detect its traces in the body. For this is believed to be an effective weapon for the murders. In 2006 the death of Russian intelligence agent, Alexander Litvinenko, did discuss. Among the causes of death uncertain, there is the hypothesis of poisoning from polonium, the agent would have ingested by eating sushi.

3. Arsenic

Elemental arsenic has an LD50 of about 13 mg, a highly toxic level superior to some of the substances in this list. It is used in alloys and in the manufacture of glass. Although the lethal dose is high, the compounds of arsenic are generally considered short form. In the event that these compounds are absorbed are disposable through feces and urine. Nevertheless, the Agency for toxic substances and Disease Registry appointed him among the most dangerous substances.

2. snake venom

Most snake poisons are formed from a mixture of many toxic proteins, often with LD50 of less than 1 mg. A key complication, however, is the speed of poison in the bloodstream. A powerful poison, but with a slow action could leave sufficient time to intervene. While a fast-acting poison with a lower LD50 might kill you before being able to get help.

1. Botuliniche Toxins

Although they are used in cosmetics, neurotoxic proteins of BOTOX are considered the most toxic substances known up to now. Experiments on mice have shown that non-lethal quantities, be able to paralyze the limbs concerned. Studies confirm that the symptoms caused by botulin toxin are flaccid paralysis, muscle weakness, difficulty of movement, decoupling of the muscles of the pharynx and voluntary muscles, and in fatal cases, paralysis of the respiratory muscles. On the basis of a few hundred grams LD50 of the toxic substance, are deadly. Between 1932 and 1945, the Japanese Unit 731 did experiments on humans by administering the Botox to prisoners during the occupation of Manchuria.
