Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A study to assess the long-term effects of sodium bromide after a single exposure on nitrogen transformation activity of soil microorganisms was performed in accordance with OECD No 216. The test material showed no significant effect on the nitrogen transformation activity of soil microorganisms at a test concentration of 1000 mg bromide / kg over a 28-day period.

Additional information

Potassium bromide is an inorganic salt that dissociates to its composite ions in aqueous solutions at environmental pH and temperature. Comparison of the available data on the various bromide salts have shown that the bromide ion is the relevant ion for determination of the toxicological profile with simple cations such as potassium, sodium or ammonium, that are ubiquitous in nature, having little or no influence on the bromide ion properties. It is therefore justified to read-across data from other inorganic bromide salts to potassium bromide.

A study to assess the long-term effects of sodium bromide after a single exposure on nitrogen transformation activity of soil microorganisms was performed in accordance with OECD No 216

The study was performed on one soil with a limit test concentration of 1000 mg bromide/kg soil with a 28 day incubation period.

The test material showed no significant effect on the nitrogen transformation activity of soil microorganisms at a test concentration of 1000 mg bromide / kg over a 28-day period.

The test material can be considered to have no long-term effect on nitrogen transformation in soil.
