WebStudy Design and Methods: In addition to capillary and venous hemoglobin, the iron status of 99 frequent blood donors was assessed by various venous blood parameters and zinc protoporphyrin IX (ZnPP). WebZinc protoporphyrin (ZPP) concentrations are widely used as biomarkers for lead toxicity. Ferrochelatase is another crucial enzyme that catalyzes the insertion of iron into protoporphyrin IX. However, in the cases of Pb toxicity, this enzyme is inhibited and the pathway is interrupted.
