Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
Based on the physico-chemical properties of EDDHMA-Fe, it is not expected that adsorption to soils or sediments will be of significance.
However, the ability of EDDHMA-Fe to generate acute toxic effects in Eisenia foetida foetida was investigated during an exposure period of 14 days and, if possible, to determine the LC50 and the NOEC at the observation times. The procedures used were according to the OECD Guideline 207 on Earthworm Acute Toxicity Test. EDDHMA-Fe did not induce significant acute mortality of Eisenia foetida foetida at >= 1600 mg/kg dry soil (i.e. 1000 mg a.i./kg dry soil) after 14 days of exposure (NOEC).
No further testing to soil organisms seems warranted, in addition, the application of the substance is as fertiliser for plants, hence negative effects to plants are not directly anticipated.
For the structurally very similar substance EDDHA-FeNa, data are available for three species of birds, indicating low acute oral or dietary toxicity (LC/LD50 values > 6000 mg/kg bw) .
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.
