Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Information on the short-term toxicity to aquatic invertebrates is available for two category members: metal chelates with copper and zinc. The result is in line with the expectations i.e. that the aquatic toxicity is the result of the free (metal) ion that is complexed and that this ion is much less bioavailable and thus less toxic to aquatic life when complexed with chelating agents. As expected, the order of aquatic toxicity of the metal chelates follows the order of toxicity of the metal ions: copper chelate is more toxic than zinc chelate. Therefore, it is reasonable to assume that the aquatic toxicity of the reaction mass of Mg-EDTA, Mg-DTPA and Mg-HEDTA will be lower than that of the zinc chelate.
The EC50 for Daphnia magna (OECD 202) was determined to exceed 1118 mg/L for the zinc chelate.
Considering that the aquatic toxicity is determined by the metal ion and that Mg is orders of magnitude less toxic than Zn, the substance is not considered toxic to aquatic invertebrates.

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.
