Additional information

In a 72 hour acute toxicity study, cultures of green algae (Scenedesmus subspicatus, CHODAT SAG 86.81) were exposed to the test substance at nominal concentrations of 0 (control), 0.78, 1.56, 3.13, 6.25, 12.5, 25, 50 and 100 mg/L under static conditions in accordance with EU method C.3. NOEC, EC10 and EC50 values based on growth rate were 25 mg/L, 58.1 mg/L and above 100 mg/L. No compound related phytotoxic effects were observed during the study.
