Additional information
A study was performed to assess the acute toxicity of the test item to Daphnia magna. The method followed was designed to be compatible with the OECD Guidelines for Testing of Chemicals (April 2004) No 202, "Daphniasp., Acute Immobilisation Test" referenced as Method C.2 of Commission Regulation (EC) No. 440/2008.
Following a preliminary range-finding test, twenty daphnids (4 replicates of 5 animals) were exposed to an aqueous solution of the test item at a concentration of 100 mg/L for 48 hours at a temperature of 20°C under static test conditions. Immobilization and any adverse reactions to exposure were recorded after 24 and 48 hours.
Analysis of the test preparations at 0 and 48 hours showed measured test concentrations to be 103% of nominal value and so the results are based on nominal test concentrations only.
Exposure ofDaphnia magnato the test item gave an EC50value of greater than 100 mg/L. The No Observed Effect Concentration was 100 mg/L.
It was considered unnecessary and unrealistic to test at concentrations in excess of 100 mg/L.
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.
