Iron
formula: Fe; CAS Registry Number: 7439-89-6
Naturally occurring transition metal
Iron is a widespread metal which is used by man in numerous applications. Most important is its role in iron and metal working industries but it is also used in chemical and pharmaceutical industries.
For animals, plants and most bacteria iron is an essential trace element. Plants and animals are thus capable of regulating their body concentrations to avoid iron deficiency.
To animals and plants iron is only slightly toxic. Since it is regulated by organisms, its bioaccumulation potential is low.
