Description of key information
The Daphnia magna Reproduction Test (semi-static, 21 d) of the test item was conducted according to OECD 211 in year 2013. The statistically significant increase of the reproductive output at the concentration level of 50.0 µg/L, followed by a statistically significant reduction of the reproductive output and a biologically significant adult mortality of 40 % at the concentration level of 100 µg/L were the most sensitive effect in this study. Based on the statistically significant difference of the reproductive output at the concentration levels of 50.0 and 100 µg/L in comparison to the control, the No Observed Effect Concentration (NOEC) after 21 days was assessed at 25.0 µg/L and the Lowest Observed Effect Concentration (LOEC) was assessed at 50.0 µg/L.

Additional information
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.
