Additional information
Key study: An acute immobilisation test on Daphnia magna was performed in accordance with EU Method C2 and OECD 202. Based on preliminary range-finding test, 20 daphnids (5 per replicate) were exposed to nominal concentrations of 6.25, 12.5, 25, 50 and 100 % v/v saturated solution (corresponding measured geometric means 2.15; 4.80; 10.04; 21.01 and 37.26 mg/L) over an exposure period of 48 hours in a closed static system. The 48h-EC50 was determined to be 14.85 mg/L in Daphnia magna (based on measured concentration and mobility) in a static closed system.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
