Description of key information
Data waiving (other justification):
The studies (simulation testing on ultimate degradation in surface water and sediment simulation testing) do not need to be conducted because the substance is inorganic.
Key value for chemical safety assessment
Additional information
These assays of biotic degradation are needed if the screening test performed in the lower annex reveals further need of investigation. As cerium dioxide is an inorganic substance, the biodegradation screening is not applicable. By deduction, the biodegradation tests in the higher annexes are not applicable too.
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.
