Description of key information
With high probability not harmful to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 1 000 mg/L
Additional information
The toxicity of the test substance on Scenedesmus subspicatus was measured in a GLP guideline study according to 92/69/EEC. The EC50 value on the growth rate of the organisms was determined to exceed 1000 mg/L (Hüls AG PZ-96/03, 1996). Therefore, the test substance is considered with high probability acutely not harmful to aquatic algae.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
