Description of key information

Additional information

Hydrogen bromide (HBr) is an inorganic substance. Upon contact with water, HBr reacts rapidly to form hydrobromic, which dissociates to hydrogen and bromide ions. It is not feasible to perform bioaccumulation testing on HBr itself. An estimation of the log Kow for hydrogen bromide is 0.6287 (Annex VII Section 7.8), so it has a low potential for bioaccumulation.
