Additional information
A study was conducted to determine the acute toxicity of the substance to Daphnia magna according to OECD Guideline 202. Groups of twenty daphnids were exposed to the substance at nominal concentrations of 0.625, 1.25, 2.5, 5 and 10 mg/L under static conditions for 48 hours. Test substance concentrations were measured in samples taken from the test solutions at test start and end. Observations of mortality were made at 24 and 48 hours of exposure. Under the study conditions, the measured 48 h EC50 of the substance in Daphnia magna was determined to be 2.94 mg/L (equivalent to 2.90 mg a.i./L) (Jenkins, 1995).
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.
