Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

This endpoint is covered by the category approach for soluble iron salts (please see the section for physical and chemical properties for the category justification/report format). Testing for this endpoint has been waived in accordance with column 2 and Annex XI, part 3, restrictions.
There are no standard terrestrial toxicity tests reported in the literature, but data on effects of soluble iron salts in irrelevantly high concentrations in food are known from the literature. Thus these experiments are not relevant as this exposure path is irrelevant assessment.
Efroymson et al. (1997) provide some information on the toxicity of iron to terrestrial arthropods. The reviewed study (Nottrot et al 1987) evaluates the effects of iron in the diet of a springtail (Orchesella cincta) fed green algae (Pleurococcus spp.) containing various concentrations of iron for 21 days. Percent growth, feeding activity, and molting were determined. Growth of the springtails was reduced 42 % by a diet containing 7'533 mg/kg of iron, but a diet containing 3'515 mg/kg of iron had no effect. The publication of Nottrot et al (1987) does not provide sufficient details (e.g. with regard to soil organic matter and pH) and was thus rejected for the assessment. Nonetheless the data may indicate the level of effects and may be used in a weight of evidence approach.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
