Description of key information
In the assessment of lithium neodecanoate, read-across to the assessment entities lithium cations and neodecanoate is applied since the ions of lithium neodecanoate determine its fate and toxicity in the environment.
Based on an acute toxicity test of Oncorhynchus mykiss and a soluble lithium salt (Li2CO3), a 96-h LC50 of 5.70 mg Li/L was derived. Regarding neodecanoic acid, the 96-h LL50 for O. mykiss is > 100 mg/L (measured) based on a reliable OECD 203 equivalent study. In sum, lithium neodecanoate has a low potential for acute toxicity to fish.
Thus, lithium neodecanoate seems to have a low potential for acute toxicity to fish.
Key value for chemical safety assessment
Additional information
In addition, toxicity data are available on three freshwater species (G. elegans, P. Lucius, D. rerio) from studies rated “reliable 3” due to methodological deficiencies. The soluble lithium salt lithium chloride (LiCl) was tested, yielding a 24-h LC50 of 1.44 mg Li/L (D. rerio) and a 96-h LC50 of 17 mg Li/L (P. Lucius), indicating a some potential for acute toxicity of lithium ions to fish.
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.
