Ecological Information

Environmental toxicity, biodegradation, and bioaccumulation data

12.1 Toxicity

Data are experimentally not accessible. Under standard test conditions, the ferrous ion, Fe2+, is unstable and is oxidised to the ferric, Fe3+, ion. Ferric iron salts have a high rate of conversion to insoluble ferric hydroxide, in consequence, Fe2+ is to a great extent removed from the test system. Furthermore, iron plays an important role in biological processes, with iron homeostasis being under strict control. In conclusion, iron is not considered to be toxic to the aquatic environment under normal conditions.

Iron is not considered to be toxic to the aquatic environment under normal conditions.

12.2 Persistence and degradability

Not relevant for inorganic substances.

12.3 Bioaccumulative potential

Iron is a bioessential trace element for organisms and plays an important role in biological processes. The uptake of iron is strictly controlled by homeostatic process. In conclusion, bioaccumulation poses no concern.

Bioaccumulation poses no concern.
