Description of key information
In a static immobilization test, Daphnia magna STRAUSS were exposed to the test item for 48 hours according to DIN 38412. The 48h-EC50 was determined to be 286 mg/L (test item) and 160.4 mg/L (act. ingr.). All reported results refer to the nominal concentrations.
Key value for chemical safety assessment

Additional information
ln the acute immobilization test with Daphnia magna (STRAUS), the effects of the test substance with a nominal loading of 100, 180, 320 and 580 mg/L were determined according to DIN 38412. No analytical determination of the concentrations of the test substance was done. The mobility of the Daphnia was determined in a static 48-hour test by visual observation after 3, 6, 24 and 48 hours. A reference substance (potassium dichromate) for the positive control was used. The 24h-EC50 of the reference substance was determined to be 1.70 mg/L, therefore the validity criteria were met. The 48h-EC50 of the test substance was determined to be 286 mg/L (test item) and 160.4 mg/L (act. ingr.). The reported results refer to nominal concentrations.
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.
