Toxicology
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Vanadium is absorbed mainly via inhalation, though small amounts can be absorbed through the skin and gastrointestional tract. It is rapidly distributed in the plasma, mainly to the kidney, liver, lungs, heart, bone, where it tends to accumulate. With the help of cytochrome P-450 enzymes, it can interconvert between its two oxidation states, vanadyl (V+4) and vanadate (V+5). Both states of vanadium can reversibly bind to transferrin protein in the blood and then be taken up into erythrocytes. Vanadium is excreted mainly in the urine. (L837)
Uses & manufacturing
UsesVanadium(IV) oxide, especially in its nanocrystalline form, may find use in glazing applications, extremely fast optical shutters, optical modulators, infrared modulators for missile guidance systems, cameras, and data storage. (L848)
