Identification
Common NameIron
ClassSmall Molecule
DescriptionA metallic element found in certain minerals, in nearly all soils, and in mineral waters. It is an essential constituent of hemoglobin, cytochrome, and other components of respiratory enzyme systems. Its chief functions are in the transport of oxygen to tissue (hemoglobin) and in cellular oxidation mechanisms. Depletion of iron stores may result in iron-deficiency anemia. Iron is used to build up the blood in anemia.

Toxicity Profile
Route of ExposureThe efficiency of absorption depends on the salt form, the amount administered, the dosing regimen and the size of iron stores. Subjects with normal iron stores absorb 10% to 35% of an iron dose. Those who are iron deficient may absorb up to 95% of an iron dose.
Mechanism of ToxicityIron is necessary for the production of hemoglobin. Iron-deficiency can lead to decreased production of hemoglobin and a microcytic, hypochromic anemia.
MetabolismNot Available
Toxicity ValuesIn a young child, 75 milligrams per kilogram is considered extremely dangerous. A dose of 30 milligrams per kilogram can lead to symptoms of toxicity. A peak serum iron concentration of five micrograms or more per ml is associated with moderate to severe poisoning in many.
Lethal DoseEstimates of a lethal dosage range from 180 milligrams per kilogram and upwards.
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesUsed in preventing and treating iron-deficiency anemia.
