Description of key information

With high probability acutely not harmful to aquatic algae.

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
100 mg/L
EC10, LC10 or NOEC for freshwater algae:
98.5 mg/L

Additional information

In a 72-hour static GLP test with the green alga Scenedesmus subspicatus (new name: Desmodesmus subspicatus) according to EU method C.3 the algae toxicity of the substance was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) of >100 mg/L, the EC10 was estimated to be 98.5 mg/L related to the analytically verified nominal concentration, respectively.
