Additional information
Acute immobilisation in Daphnia has been investigated in screening tests of 48 hours duration and conducted based on OECD test methods. The EC50 (48h) was determined to be in the region of 100 mg/L. A definitive test conducted in compliance with OECD test methods resulted in an EC50 (48h) of 32.3 mg/L (nominal concentration), a LOEC of 25.0 mg/L (nominal concentration ) and a NOEC of 12.5 mg/L (nominal concentration).
(Q)SAR estimation indicates an EC50 in excess of 100 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.
