Description of key information

In accordance with section 1 of REACH Annex XI, the study on long-term toxicity to fish does not need to be conducted. Natural baseline iron concentrations in the aquatic environment are already much higher than the reported saturation concentrations of iron oxides in the environment (Arche 2010). As such it is unlikely that iron ions released from iron oxides would inhibit growth and proliferation of aquatic plants, animals or microorganisms.
