Elimination Cobalt (Co)

  • Fecal excretion, the major route of Co excretion in humans, was effected by the species of Co given. Fecal clearance increased with increasing particle size and decreasing solubility. Fecal excretion of Co from the insoluble cobaltic-cobaltous oxide (Co3O4) was > 96% whereas it was 70-83% of the more soluble Co chloride (Ayala-Fierro et al., 1999; Bailey et al., 1989). Dogs excreted 90% of the Co from Co3O4 in the feces whereas 70% of the Co from Co nitrate.  

  • Co chloride was eliminated more rapidly then Co protoporphyrin.
