Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The EC50 for Daphnia magna was determined to be 35.19 µg Pd L-1
Key value for chemical safety assessment
Additional information
Pd(IV) will not remain in biological and environmental systems due to its inherent instability, ease of reduction to Pd(II) and its ability to reductively form strong complexes with organic nitrogen and sulphur-containing moieties. Therefore, ecotoxicity results are read across from palladium(II) to palladium(IV) substances. For palladium substances, the available ecotoxicity data indicates that substances with a chloro ligand are more toxic than those with no chloro ligand. As this substance has a chloro ligand, it is appropriate to read across ecotoxicity results from diamminedichloropalladium. The EC50 for Daphnia magna determined for diamminedichloropalladium is 35.19 µg Pd L-1 (Schlechtriem 2012). The result was determined in a study following OECD guideline 202, with five test concentrations. Test solutions were analysed by ICP-MS and the results based on mean measured concentrations.
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.
