Description of key information
The test substance was tested for immobilisation of Daphnia magna according to OECD guideline No. 202: "Daphnia sp. Acute Immobilisation Test", adopted April 13, 2004 and Commission regulation (EC) No. 440/2008 of 30 May 2008, Part C.2: “Daphnia Sp. Acute Immobilisation Test”, Publication No. L142.
The 48h-EC50 was >100 mg/L based on analytically confirmed nominal concentrations.

Additional information
The toxicity of the Lithium salt of branched-aliphatic dicarboxylic acid towards Daphnia magna was evaluated in a reliable study according to the appropriate standard test methods EU Method C.2 (Daphnia Sp. Acute Immobilisation Test) and OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test).
A combined limit range-finding test was performed, exposing twenty daphnids per concentration (four replicates, five daphnids per replicate) to a control and to a nominal Lithium salt of branched-aliphatic dicarboxylic acid concentration of 100 mg/L.
In addition ten daphnids per concentration (two replicates, five daphnids per replicate) were exposed to nominal concentrations of 0.10, 1.0 and 10 mg/L. The total exposure period was 48 hours. The 48h-EC50 was >100 mg/L based on analytically confirmed nominal concentrations.
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.
