Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
A 24h TDp screening test showed only partial dissolution of the test item. As such, a potential contribution of non-dissolved and/or non-dissociated Palladium (II) acetate to the ecotoxic potential of this substance can not be excluded, and a grouping with and read-across from other soluble inorganic palladium substances is not performed. Instead, substance specific ecotoxicological information is generated and the environmental classification is assessed based on the lowest acute and chronic values from substance specific ecotoxicity test data.
The lowest acute value is an EC50 of 2.64 µg palladium (II) acetate/L for algae tox (growth rate). The lowest chronic value is an EC10 of 1.32 µg palladium (II) acetate/L for algae tox (growth rate).
These threshold values are used for classification purposes. The corresponding environmental classification is:
Acute Category 1 (M-factor 100)
Chronic Category 1 (M-factor 10).
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.
