Additional information
Key study: An Acute Immobilisation Test in Daphnia magna was performed according to OECD Guideline 202 (GLP study). 20 Daphnids (<24 hours old, in 4 replicates) per concentration were exposed up to 1.92 mg/L (in the filtrate of a loading of 100 mg/L, highest achievable concentration) test item for 48 hours under static conditions. The EC50 (48 h) was determined to be 1.73 mg/L based on immobilization. The LOEC (48 h) and NOEC (48 h) were determined to be 1.92 mg/L and 0.87 mg/L respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
