This report measured bioaccessibility of Zirconium carbide as a
surrogate for bioavailability. Thus, the soluble zirconium was measured
by using EPA Method #200.8 (ICP/MS) after incubation of Zirconium
carbide in different simulated body fluids (simulated gastric fluid,
simulated interstitial fluid, simulated lysosomal fluid, and artificial
perspiration). Results were reported as µg Zr/g sample, % Zr release/Zr
content. The release of zirconium ions from Zirconium carbide was very
low in artificial body fluids. The results of the study are summarized
in the table below:
