Description of key information

(72 hr) EC50 437 mg/L growth rate Scenedesmus subspicatus. Reliability 1.

Key value for chemical safety assessment

Additional information

A 72-hour EC50 value of 437 mg/L and NOEC of approximately 57 mg/L have been determined for the effects the test substance on growth rate of Scenedesmus subspicatus (EU Method C.3 Algal Inhibition test, Hüls AG, 1994c). The results are interpreted with reference to nominal concentrations of the test substance. However it is likely that the test organisms were primarily exposed to the hydrolysis products of the substance.
