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 9.2.2.1 Hydrolysis). Oxidants produced from bromine in water are known to be very toxic to aquatic organisms and very reactive. This fact is reflected in the EU Classification and Labelling of bromine as it is classified/labelled with the symbol “N” (dangerous for the environment) and the risk phrase “R50” (very toxic to aquatic organisms). 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.
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.
