Table 1.
Average metal and phosphorus concentrations in blood plasma from the portal vein and either the caudal or cranial vein. Values reported for each pig are the average of time points before and after 57Fe injection. Values are the average of n = 4–10 independent samples collected at different times during the experiment. Concentrations of Mn and Co were below detection. Corresponding 57Fe values are in Figure 2. *In P4, the high concentration of 56Fe is due to ferric gluconate infusion. The significant uncertainty in iron concentrations may be due to variable levels of hemolysis.
