Description of key information
Daphnia Magna was exposed under static conditions for 48 h to six concentrations (0.63, 1.25, 2.5, 5, 10, and 20 mg/L). An EC50-value of 4.5 mg/L was observed.
Key value for chemical safety assessment
Fresh water invertebrates

- 4.5 mg/L
Additional information
The toxicity towards aquatic invertebrates was performed in a study, conducted in accordance with EEC Methods for Determination of Ecotoxicity Annex to Directive 92/69/EEC, Part C which is in most parts equivalent to the OECD Guideline No. 202.
Daphnia magna was exposed to the test solutions of 6 nominal concentrations of the test substance and blank control solution for a period of 48 h under static conditions. Mobility and visible abnormalities were recorded at 24 and 48 h. The measured concentrations used to determine the EC-values confirmed that deviation from the nominal concentrations was less than 20 %. An EC50-value of 4.5 mg/L was obtained. The toxicity study is classified as acceptable and satisfies the guideline requirements for the acute Daphnia study.
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.
