Description of key information

The acute toxicity of Diketone to alga (Desmodesmus subspicatus) was tested according to OECD guideline 201 (Alga, Growth Inhibition Test). During 72 hours exposure an EC50 of > 30.5 mg/L and a NOEC of 3.8 mg/L was measured.

Key value for chemical safety assessment

EC50 for freshwater algae:
30.5 mg/L
EC10 or NOEC for freshwater algae:
3.8 mg/L

Additional information

"should read > 30.5 mg/L"

Diketon does not show any toxic effects to alga till the limit of water solubility and therefore no classification is needed basend on this study.
