Description of key information

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