Elimination - Uranium (U)
The elimination of U is influenced by its chemical species.
Uranyl-bicarbonate and uranyl-citrate complexes are ultrafiltrable in
blood, therefore cleared by the glomeruli. Their clearance in animals is
5 to 10 plasma volumes daily, in contrast to the low clearance of U(IV)
because it is mostly protein bound
Excretion of the less soluble U(IV) is less than U(VI) (10 and 50% in 24
(Voegtlin and Hodge, 1953).
