It was opened in 1830 by the Swedish chemist N. Sefstrom.This element is capable of forming a compound with a beautiful color, and so his name is associated with the name of the Scandinavian goddess of beauty Vanadis.The human body is contained in small quantities, therefore it ultramicroelements chemists call (content in the body is not more than 0.000001%).But despite this, he is involved in many chemical reactions and is important for our health.

Properties



In appearance resembles steel but at the same time is a ductile metal.The melting point is 1920, point - 3400 degrees.

Interaction: is resistant to dilute nitric acid, hydrochloric acid, sulfuric acid, and the sea water, alkalis.With halogens forming halides or oxohalides, with oxygen - several oxides.

In humans interact with proteins and chlorine - so they reduce its toxic effects.Contribute to increase toxicity of vanadium and iron, an aluminum compound, ascorbic acid.For removing high content in the body prescribers chromium EDTA aimed at
eliminating toxic substances.

The water falls from vanadium and iron ores, production waste: oil refining, heavy industry enterprises.The soil is maintained long enough, and the plants in it a little.

Vanadium in humans



Its content is approximately 100 g is located in the muscle tissue and bone, thyroid, lungs, kidneys, heart muscle, and spleen.

Like other elements, vanadium has many functions:
  1. Increases the body's defenses (helps cells-phagocytes to destroy all foreign substances), which helps cleanse the blood, tissue and improve immunity.

  2. exhibit antioxidant properties, controls the level of glucose in the blood and prevents atherosclerosis.

  3. Supports healthy structure of the tooth and bone tissue (helps to be distributed calcium salts).

  4. reduces the amount of cholesterol in the blood, normalize lipid metabolism, lowers blood pressure and maintains in good condition the vessels of the heart and brain.

  5. Supports carbon metabolism, regulates the balance of sodium and potassium.

  6. Relieves swelling of tissues, prevents the development of cancer cells.

  7. In conjunction with zirconium well affects the lungs, liver, spleen, thyroid and pancreas, urinary and pituitary.

Which foods contain vanadium



Which foods contain vanadium

brown rice, barley, buckwheat, peas, beans, oats, potatoes, radishes, peppers, lettuce, beets, parsley (read about harm parsley), fennel, carrots, strawberries, cherries, cereals, animal fats, vegetable oils, mushrooms, soy, fatty meat, liver, fish and some seafood.

source of vanadium, safe for health, found in royal jelly of bees and honey in the comb.

deficit



Lack of vanadium may increase the risk of diabetes and, conversely, when diabetes develops its deficit.

also a shortage in the body of this element is associated a specific vanadium-deficient schizophrenia, atherosclerosis.Lack detected by biochemical analysis of blood, where there are changes in indicators such as phospholipids (raised), triglycerides (increased), cholesterol (reduced).

Overdose



High concentration of vanadium can be found in workers engaged in the production of asphalt, glass and fuel.They often suffer from asthma, eczema, inflammatory skin diseases, respiratory and vision.

poisoning occurs when the total dose of 0, 25 mg, and 2-4 mg can be fatal.The excess of the victims have manifested in the form of acute or chronic intoxication.

Acute intoxication is accompanied by inflammation of the mucous membranes of the throat, lungs and eyes, allergic reactions on the skin.In an analysis of blood marked decrease in white blood cells (leukopenia) and the level of hemoglobin (anemia).

Chronic intoxication reduced the concentration of ascorbic acid decreases the amount of cysteine ​​in hair, increased risk of cancer pathology and respiratory diseases.
