Skin diseases caused by vanadium and its compounds

Industrial application: Vanadium is a rare metal with a high melting point (1710 ° C), which is mainly used in the manufacture of iron-vanadium alloys in industry. Vanadium-containing ore can be exposed to vanadium dust during mining, crushing and packaging; using vanadium pentoxide (V2O5) as a catalyst, there is also the opportunity to contact its dust. The heavy oil after petroleum fractionation contains a large amount of vanadium. Oil burners can come into contact with vanadium oxides during cleaning.
