Additional information

Bromide ions would be expected to partition to water rather than soils and sediments in the environment given their high water solubility (ca. 90 g per 100 ml for sodium bromide) and the negative charges on the ions.

A bioconcentration factor for sodium bromide in aquatic invertebrates has been determined experimentally to be 0.23 (Bartolomé M.C.et al., 2005). In addition, a bioconcentration factor for aquatic organisms has been calculated, giving BCFfish = 1.41 L/kgwet fish (D. Carling, 2007). Given this data, it is considered that there is minimal risk of bioaccumulation and of secondary poisoning to the aquatic compartment.
