Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Additional information
Information on adsorption / desorption is relevant to estimate where a substance will be found in the environment and how it may partition between environmental compartments.
Cerium metal can be expected to have a low potential for adsorption based on its very low solubility in water and therefore, its dependence on a particular metal-specific mechanism to be bounded.
For the estimation of the adsorption / desorption properties of cerium metal read-across to cerium-soluble compounds (Ce3+) was done, according to the read-across strategy explained for ecotoxicological properties. This corresponds to a worst-case scenario, because there is no relevant exposure of cerium metal in the environment according to the uses identified and, additionally, only a very small fraction may become soluble.
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.
