Description of key information

Toxicity to algae was determined in a study according to OECD Guideline 201 (Alga, Growth Inhibition Test)in Scenedesmus subspicatus (new name: Desmodesmus subspicatus) under static conditions.
No effects on biomass as well as growth rate occurred at concentrations up to and including 100 mg/L (Nominal concentration).
The NOEC based on growth rate as well as based on biomass was 100 mg/L (Nominal concentration) after 72 hours.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
100 mg/L

Additional information

The test item did not inhibit algal growth. The EC50 was > 100 mg/L. The NOEC was 100 mg/L The values based on nominal test concentrations.
