Description of key information

The EC50 (72 h) was determined to be > 100 mg/L. The corresponding EC10 value was at least 100 mg/L.

Key value for chemical safety assessment

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

Additional information

The short term toxicity of the substance to aquatic algae and cyanobacteria was tested in Scenedesmus subspicatus (new name: Desmodesmus subspicatus) in a study performed according to OECD Guideline 201, 1984. Based on the results obtained from testing the EC50 (72 h) was determined to be > 100 mg/L. The corresponding EC10 value was at least 100 mg/L. No mortalities or any other effects which could be related to the test item were noted during the course of the study. Thus, the substance was considered to be practically non toxic to aquatic algae and cyanobacteria.
