Additional information

A 72-hour EC50 value of >0.0079 mg/l and NOEC of ≥0.0079 mg/l have been determined for the effects of the test substance on growth rate ofScenedesmus subspicatus. The measured concentrations represent the maximum obtainable concentration in solution under the conditions of the test; no effects on algae were observed at this concentration.
