Description of key information
Additional information
Short-term toxicity
The short-term toxicity to aquatic organisms studies that have been entered to assess the aquatic toxicity of cerium trifluoride, have all been read across from the structurally similar substance dicerium tricarbonate. Both substances additionally have similar toxicological and environmental profiles and therefore this read across is considered acceptable.
The results are as follows:
96 hour LL50 to Oncorhynchus mykiss > 100 mg/L
48 hour LL50 to Daphnia magna > 100 mg/L
72 hour EL50 to Scenedesmus subspicatus > 100 mg/L
Long-term toxicity
In accordance with Column 2, specific rules for adaptation from Column 1, of REACH Annex IX, the long-term testing on daphnia and fish studies, listed under standard information requirements 9.1.5 and 9.1.6 respectively, do not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment is not applicable for inorganic substances, so no further testing is required.
Classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material does not require classification for aquatic toxicity.
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.
