Description of key information

The short term toxicity of Vestagon HA 320 on algae was determined by Hüls Infracor GmbH according to OECD 201 under static conditions. Aquatic algae were exposed to a limit concentration of 1000 mg/L for 72 hours. The influence of the test substance on the growth rate  was evaluated.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
1 000 mg/L

Additional information

Up to a substance concentration of 1000 mg/L no effects on algae could be observed.
