Description of key information
In a 72 hour acute toxicity study, the cultures of Scenedesmus subspicatus were exposed to test material at nominal concentrations of 0, 10, 20, 40, 80, and 160 mg/L under static conditions in accordance with the OECD guideline 203.
The EL50 and NOELR values based on cell density were > 160 and 20 mg/L nominal loading rate concentrations, respectively.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 160 mg/L
- EC10 or NOEC for freshwater algae:
- 20 mg/L
