Description of key information
The significant reduction of the reproductive output at the concentration levels of 33.9 and 69.3 mg/L was the most sensitive effect in this study.
Based on the significant reduction of the reproductive output at the concentration levels of 33.9 and 69.3 mg/L, the No Observed Effect Concentration (NOEC) after 21 days was assessed at 16.6 mg/L and the Lowest Observed Effect Concentration (LOEC) was assessed at 33.9 mg/L.
An EC50-value for the reduction of the reproductive output could not be calculated, because the reduction was limited to a maximum of 21 % within the tested concentration range. The EC10-value for the reduction of the reproductive output was calculated to be
9.98 mg/L.
