Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Bromide ions are known to be naturally present in soils in varying background concentrations. Published data have been summarised (Flury M., et al., 1993) indicating an average concentration of ca. 1 mg(Br-)/kg for typical soils throughout Europe. These observations are supported by soil bromide concentrations determined in a number of soils in the UK ranging from 0.3 to 1.6 mg(Br-)/kg (Maw G.A., et al., 1982). Further data have been published detailing soil water bromide levels of 0.5 mg(Br-)/L (Hill A.R., et al., 1998) for soils in Canada, and soil bromide levels of 0.5 to 1.6 mg(Br-)/kg (Hatton T.J., et al., 2002) for soils in Australia.
Consequently an approximate background level of 1 mg(Br-)/kg in soil, as presented by Flury, et al., is considered justified, and such levels can be considered to result in minimal adverse effects on the flora and fauna present in such soils through chronic exposure.
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.
