Description of key information
Key value for chemical safety assessment
Additional information
Read across from NaBr to CaBr2 is possible due to the full dissociation of both compounds in water. Na+ and Ca2+ are not toxic in the concentration ranges where Br- is toxic. Therefore only the Br- is responsible for the toxicity effects.
The acute toxicity to calcium bromide to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 of greater than 100mg ai/l. Correspondingly, the No Observed Effect Concentration was greater than or equal to 100 mg ai/l.
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.
