Vanadium is grey metal of Vb of Periodic table of the elements. Vanadium as clean element does not find in nature. It is using in nuclear production, production of alloys, glass and photography. Vanadium and its compounds are very famous in chemical industry because of vanadium toxic (respiratory problems).
Origin in water
It can find in small quantities in underground waters. In Earth crust vanadium occurs in minerals like vandinite, decloasite, carnotite, corvusite, rhoscoelite and patronite. Beside this, vanadium as ingredient occurs in organic products like naphtha, bitumen and mineral coal.
Absorption in human body is very low. Vanadium in drinking water can be significant in view of total input with nutrition and small content in food.
There are suspicions in vanadium part in protection against arteriosclerosis. It prevents cholesterol making in capillaries. Vanadium is necessary for bones and teeth forming. It supports effect of insulin hormone. It helps in prevention of heart attack.
Acute toxicities at people are primary respiratory and there are not evidences about chronic oral toxicities.
