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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
PNEC values for the aquatic compartment have been derived using read-across from structurally related substances (see IUCLID section 13 for read-across document).
For sediment and soil, no PNECs can be derived as not sufficient data is available. Based on the properties no adsorption of EDTA-FeNH4(NH4)OH onto the sediment and soil has to be expected, thus the assessment of this compartment will be covered by the aquatic assessment and can be based on the pore water concentration only.
Conclusion on classification
The dataset based on read-across reveals many LC50 and EC50 values >100 mg/l but also reveals one EC50 value (converted to the submission substance) below 100 mg/l, i.e. a 48h-EC50 for Daphnia magna of 95 mg/l. However, the chronic NOECs available are all (far) above 1 mg/l. Therefore classification as hazardous to the aquatic environment is not required.
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.
