Description of key information

In a limit test Desmodesmus subspicatus was exposed under static conditions to a concentration of  100 mg/l (pH 7.9-9.0). After 72 h no toxic effects against algae were observed at a limit test concentration of 100 mg/L, corresponding to a measured concentration of < 0.0176 mg/L, which reflects the maximum water solubility under exposure conditions. 

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
100 mg/L

Additional information

"should read EC50> 100 mg/L, NOEC >= 100 mg/L"
