Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 72-hour EC50 (growth rate) was determined to be 0.063 mg L-1. The NOEC (growth rate) was 0.05 mg L-1.
Key value for chemical safety assessment
Additional information
An algal study Is available following OECD guideline 201 (Enste-Diefenbach 2003). Eight test concentrations were used and these were analysed using ICP-OES. Results were based on geometric mean values of analytically determined concentrations at test start and after 72 hours. The 72-hour EC50 (growth rate) was determined to be 0.063 mg L-1. The NOEC (growth rate) was 0.05 mg L-1.
For palladium a single, worst case PNEC value has been derived for each environmental compartment, to cover all palladium substances. The PNEC has been derived based on the most toxic palladium substance, diamminedichloropalladium. Therefore, although toxicity results for diamminedicloropalladium are likely to overestimate the toxicity of palladium substances that do not contain a chloro ligand, this data is included in the dossiers for all palladium substance as it was taken into account in PNEC derivation.
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.
