Additional information
Results from the chronic (21 days) Daphnia reproduction test was realized, following OECD 211 guidelines. The test was conducted under semi-static conditions and test solutions were renewed 3 times per week. The concentrations of EPTAC were determined at all test concentrations (0.05, 0.16. 0.49, 1.45 and 4.35 mg/L) and in controls. Samples were taken and analysed on days 0, 7, 14, 19 (fresh media, 0 h) and on days 2, 9, 16, 21 (old media, 48 h). The mean recovery rates were > 80%. All effect values are given based on the nominal concentrations of the active ingredient i.e. EPTAC. The NOEC for Daphnia reproduction rate is 0.16 mg/L, the LOEC 0.49 mg/L and the EC50 is 0.55 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.
