Description of key information

In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex X, long-term toxicity tests to sediment organisms (required in section 9.5.1) do not need to be conducted as the results of the chemical safety assessment do not indicate the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. In addition, according to its physico-chemical properties lithium hydroxide is not expected to be distributed into sediment and the ad-/desorption behaviour does not indicate that lithium will be present in the sediment. The log Kd value for sediment was found to be 2.72, i.e. adsorption potential to sediment can be regarded as neglible (refer to IUCLID section 5.4). Thus, concentration and consequently effects in sediment are negligible. Additionally, chloride naturally occurs in water and is a natural component of soil minerals. Therefore, no testing on sediment toxicity is required.
