Additional information

Abiotic degradation / hydrolysis

The performance of a test for hydrolysis as function of pH is scientifically unjustified. The study does not need to be conducted as lithium bromide completely dissociates in water forming lithium cation and the corresponding bromide anion.

Biotic degradation

Biodegradation in water: screening test, Biodegradation in water and sediment, Biodegradation in soil

In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VII, section 9.2.1.1, biodegradation tests do not need to be conducted as lithium bromide is an inorganic substance.

Bioaccumulation in aquatic/sediment

In accordance to column 2 of REACH Regulation (EC) No 1907/2006, Annex IX, section 9.3.2, the Bioconcentration Factor (BCF) does not need to be determined as lithium bromide is expected to have a low potential for bioaccumulation. The theoretical, calculated log Pow is -0.37 (EPIWIN calculation), i.e. very low, as expected for an inorganic salt. Therefore no testing on bioaccumulation is needed.

Adsorption/desorption

In accordance to column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, section 9.3.1, the adsorption/desorption screening test does not need to be conducted as due to its physico-chemical properties a low adsorption potential for lithium bromide is expected. The theoretical, calculated log Pow is -0.37 (EPIWIN calculation), i.e. very low, as expected for an inorganic salt. For risk assessment, the Koc value for lithium bromide was calculated using EPIWIN v4.10. A log Koc of 1.121 (Koc = 13.22 L/kg) was derived for lithium bromide.
