Additional information
One study is available, testing the short term toxicity of the substance to aquatic invertebrates and was performed according to the OECD guideline 202 and GLP. The water flea, Daphnia magna was exposed to nominal test item concentrations of 5, 10, 20, 40 mg/L and a control for 48 h. A static freshwater system was chosen for testing. The test item was monitored during the study via TOC analysis. The analytical recoveries were > 80% of the nominal values. The test item caused biological effects to Daphnia magna and resulted in an EC50 (48 h) of 11.3 mg/L (geom. mean meas.). The EC50 (48 h) of 11.3 mg/L (geom. mean meas.) was derived from the EC0 (48 h) = 6.8 mg/L and EC100 (48 h) = 18.8 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.
