Description of key information

ΕC50 (2h) = 1098.1 ± 13.7 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 098.1 mg/L

Additional information

The toxicity potential of the substance to green algae was evaluated after 2 hours of exposure to different concentrations of the substance (ranging from 40 -1800 mg/l). Fluorescence parameters were measured on 2 ml algal suspension after 1 and 2 h of exposure. The ΕC50 (2h) was determined to be 1098.1 ± 13.7 mg/l.

The EC50 at 96 hours was predicted by ECOSAR v.1.1 to be 50313.043 mg/l which supports that the substance is not expected to be toxic to aquatic algae.
