Additional information
Two guideline studies on the toxicity of the substance to Daphnia magna are available. In a test conducted in compliance with OECD guideline 202, the test animals were exposed to the test substance in a static test system for 48 hours. At test termination an EC50 of 14.2 mg/l based on measured test concentrations was determined ((F. Hoffmann-La Roche, 1994).
In a second test set up according to German standard DIN 38412 part L11 an EC50 of 27 mg/l based on the mobility of the test animals was determined after 48 hours (BASF AG, 1990).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.
