Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The effect of acute and chronic exposure to sodium bromide on aquatic organisms was observed in the studies reported here. Sodium bromide was found to be non-toxic to the aquatic environment.
The short term toxicity to fish studies showed that the LD50 to the most sensitive species, Juvenile turbot, is >440 mg/L, according to OECD guideline 203.
A number of chronic studies were performed with Poecilia reticulata and Oryzias latipes. The NOEC ranged from 10 to 3219 mg/L and 32 to 320 mg/L respectively. None of the validity criteria of the tests with the two species can be considered as fulfilled, as individual mortality and effect data were not given. The studies were not performed according to GLP.
A considered number of studies with Daphnia magna are available. The toxicity data show that the sensitivity of Daphnia magna to the test substance is variable, with NOECs ranging from 2.8 to >117 mg/L sodium bromide.
NOEC values were derived from acute and (semi) chronic toxicity tests with freshwater green algae, (cyano)bacteria and duckweed (Lemna minor). The test results show that the organisms have a similar toxicity to sodium bromide as the NOEC values ranged from 3200 mg/L to 4200 mg/L. For most tests no guidelines were specified.
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).
