Description of key information
Additional information
Toxicity to terrestrial organisms
Hydrogen bromide (HBr) forms hydrobromic acid in water. The toxic effect seen to organisms is from the acidity of the resulting solution, which is a function of the HBr concentration. Though there are minimal data on hydrogen bromide (HBr) available there are sufficient information available on the analogue substance hydrogen chloride (HCl). (Read-across justification Section 8.6 Repeat dose studies).
Evaluation of the analogous substance hydrogen chloride under the OECD ICCA HPV Programme (2003) stated that it was not considered useful to calculate a PNEC for hydrochloric acid because factors such as the buffer capacity, the natural pH and the fluctuation of the pH are very specific for a certain ecosystem. Hydrobromic acid will react in the same manner as hydrochloric acid, so the evaluation is equally valid for hydrobromic acid. HBr in water forms hydrobromic acid which dissociates to ions (H+ and Br-).
Toxicity data for the bromide ion is available in other submissions so adequate information for environmental classification and labelling of the dissociation products of hydrobromic acid is available. Due to solubility and dissociation of HBr in water, there will be no direct or indirect exposure to the terrestrial compartment.
Toxicity to birds
Testing for avian toxicity is not scientifically justified based on the known toxicity of the substance in mammals and humans in addition to the known toxicokinetics of HBr and metabolic products. Furthermore, avians are unlikely to be exposed to the substance due to the solubility and dissociation of HBr in water.
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.
