Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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.
A study was performed to assess the acute toxicity of sodium bromide to the earthworm (Eisenia foetida) in an artificial soil. Earthworms were exposed to a range of concentrations of bromide/kg of soil for a period of 14 days. The number of mortalities was determined after 7 and 14 days exposure. The No Observed Effect Concentration (NOEC) was 10 mg bromide/kg on the basis that no mortalities were observed after 14 days exposure and additionally no sub-lethal effects on weight or behavior were observed at 10 mg bromide/kg.
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.
