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, "Daphnia sp., Acute Immobilisation Test" referenced as Method C.2 of Commission Regulation (EC) No. 440/2008 under semi-static test conditions.
The 48-Hour EC50 for the test item to Daphnia magna based on time-weighted mean measured test concentrations was 14 mg/L with 95% confidence limits of 9.0 - 22 mg/L. The Lowest Observed Effect Concentration was considered to be 22 mg/L. The No Observed Effect Concentration was 9.0 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
