Description of key information
Key study: Test method according to the Dutch Standardization Organization Guidelines (1980, NEN 6504: Determination of acute toxicity with Poecilia reticulata). Test performed following a method equivalent or similar to the OECD Guideline 203 (Fish, Acute Toxicity Test). The 96h-LC50 and the 96h-NOEC, based on mortality and abnormal behaviour, in Poecilia reticulata were determined to be 16 g Br-/L (20.6 g NaBr/L) and 0.025 g Br-/L (0.032 g NaBr/L), respectively.
Key study: Test performed following a method equivalent or similar to the OECD Guideline 203 (Fish, Acute Toxicity Test). The 96h-LC50 and the 96h-NOEC, based on mortality and abnormal behaviour, in Oryzias latipes were determined to be 24 g Br-/l (30.9 g NaBr/l) and 0.25 g Br-/l (0.32 g NaBr/l), respectively.

Additional information
Key study: An acute toxicity test with sodium bromide on Poecilia reticulata was performed following a method equivalent or similar to the OECD Guideline 203 and in accordance with the Dutch Standardization Organization method (1980; NEN 6504). The test organisms were exposed for 96 hours to different concentrations of the test substance and they were observed for mortality and abnormal behaviour. The 96h-LC50 (based on mortality) and the 96h-NOEC (based on mortality and abnormal behaviour) were determined to be 16 g Br-/litre (20.6 g NaBr/L) and 0.025 g Br-/litre (0.032 g/L), respectively.

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.
