Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There is no data available for the target substance on toxicity towards aquatic organisms and microorganisms. However, there is data available for the source substances (manganese salts and Fe(Na)EDDHA). With regard to the data for manganese the hazard values were converted to the registered substance under consideration of the maximum percentage of manganese included in the substance. This data is used within the concept of a weight-of-evidence approach to assess the toxicity of the target substance.
Fish
LC50 (96h) = 64 mg/L for Oncorhynchus mykiss (test item: MnCl2) (WHO, 2004)

Additional information
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.
