Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (zinc salts and Fe(Na)EDDHA). With regard to the data for zinc the hazard values were converted to the registered substance under consideration of the maximum percentage of zinc 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.
