Time-dependent distribution of selenate and selenite selenium in male C57L/J mice.
The distribution and retention of selenate and selenite in C57L/J mice was investigated using 75Se radioisotope. The comparison is made with the normal distribution of the element determined by using radioisotope-induced x-ray fluorescence, RIXRF methods. The distribution of the two oxidation states measured as activity of 75Se was almost identical but differed from the normal trace elemental profile, TEP. The excretion rates of the two selenium species in the initial phase are different with more selenate being excreted than selenite in the first 2 days. It was found that the wholebody excretion rates followed a pure first-order pattern this was not true for the individual organs of the animals.
