Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.
The acute toxicity of sodium bromide solution to Juvenile turbot (Scophthalmus maximus), a marine water fish, over 96 h under semi-static conditions with 5 concentrations of test substance was assessed according to OECD Guideline 203. No mortality or other adverse effects were noted due to the administration of the test substance. LC50(48h) >342 mg (Br-)/Land LC50(96h) >342 mg (Br-)/L for the bromide ion.
The acute toxicity of sodium bromide to Bluegill sunfish (Lepomis macrochirus), a fresh water fish, over 96 h under static conditions with 5 concentrations of test substance was assessed according to US EPA-FIFRA, guideline 72-1. No mortalities or other abnormal effects were observed in any of the dose groups. Therefore the LC50 >776 mg(Br-)/L for the bromide ion.
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.
