Vanadium can enter the body via the lungs or, more commonly, the stomach. Most of the dietary vanadium is excreted. The amount of vanadium resorbed in the gastrointestinal tract is a function of its oxidation state (V(V) or V(IV)) and the coordination environment. Vanadium compounds that enter the blood stream are subjected to speciation.

The name means V Gold 10, meaning Gold quality or Gold standard. It is a stainless steel with a fine grain, capable of a very fine, sharp edge - much finer than many other steels. It was originally marketed to Japanese Chefs, but it has become a favorite in the knife community abroad. Most VG-10 steel knives are made in Japan.
In 1966, Union Carbide began mining operations and stockpiling vanadium ore in Garland County. Construction of the vanadium processing mill was completed in 1967, and vanadium oxide was produced for the first time in Arkansas in 1968. By 1970, Arkansas was a major vanadium-producing state in the nation.
