Description of key information

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
1.78 mg/L

Additional information

The 72-h NOEC for chronic toxicity of SymHelios® 1031 to algae in this study is unbounded at 1.78 mg/L (highest tested concentration) while the 72-h ErC10could not be determined (> 1.78 mg/L). Higher concentrations of SymHelios® 1031 could not be tested as the highest tested concentration corresponds to the solubility limit. Thus, no effects were observed up to the water solubility limit.
