Bromine is an inorganic substance and does not under go biodegradation to form carbon dioxide.

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. 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.
