Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bromine in contact to water forms a mixture of brominated oxidants such as hydrobromic and hypobromous acids (See Annex VIII Section Hydrolysis). Oxidants produced from bromine in water are known to be very toxic to aquatic organisms and very reactive. Inorganic bromide is the principal ultimate degradant from reaction of these species. Bromide occurs naturally in the environment.

In the presence of natural waters or test media containing biological molecules, other brominated oxidant species may also be formed.

Thus, adsorption of bromine itself is unlikely. Negative anions such as bromide are known not to sorb to soil. Bromide itself has been used to monitor ground water flow through soil; its mobility in soil is similar to water.
