Description of key information
Data waiving (other justification):
In accordance with column 2 of REACH annex X, long-term toxicity testing on sediment shall be proposed by the registrant if the results of the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The choice of the appropriate test(s) depends on the results of the chemical safety assessment. Cerium dioxide does not meet the criteria to be classified as a dangerous substance. In particular, the results from the ecotoxicity tests performed on the different environmental compartments do not reveal any adverse effect. As a non classified substance, cerium dioxide does not required an exposure assessment and a risk characterization. In the absence of risk characterization, no refinement is necessary, especially for the PNECs. As a result, there is no need to launch a test for the sedimentary compartment.

Additional information
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.
