Description of key information
In the assessment of strontium 2-ethylhexanoate long-term toxicity to aquatic invertebrates, read-across to the assessment entities soluble strontium substances and 2-ethylhexanoic acid is applied since the ions of strontium 2-ethylhexanoate determine its toxicity in the environment. Chronic toxicity of 2-ethylhexanoate to Daphnia magna was assessed in an OECD 211 conform study, yielding an 21-d NOEC of 25 mg/L 2-ethylhexanoate. In addition, a 21-d NOEC of 18 mg/L was derived from supporting studies according to OECD 211 (Daphnia magna). Studies on long-term toxicity of strontium ions to aquatic invertebrates resulted in a 21-d NOEC of 21 mg strontium/L (Daphnia magna). Since all respective NOEC values of strontium and 2-ethylhexanoate are well above the OECD limit for chronic toxicity tests, the potential of strontium 2-ethylhexanoate for long-term toxicity to aquatic invertebrates is expected to be low.

Additional information
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.
