Biological Activity
Vanadium(V) oxide exhibits modest toxicity to humans, with an LD50 of about 470 mg/kg. The greater problem is with inhalation of the dust, where the LD50 ranges from 4-11mg/kg for a 14 day exposure. Vanadate (VO43−), formed by hydrolysis of V2O5 at high pH, appears to inhibit enzymes that process phosphate (PO43−). However the exact mode of action remains elusive.

Famous quotes containing the words biological and/or activity:
“If the most significant characteristic of man is the complex of biological needs he shares with all members of his species, then the best lives for the writer to observe are those in which the role of natural necessity is clearest, namely, the lives of the very poor.”
—W.H. (Wystan Hugh)
“In communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.”
—Karl Marx (1818–1883)
