Description of key information

The substance showed no significant respiration inhibition of activated sludge at the highest concentration tested, and hence the IC50 is > 100 mg/L (based on nominal concentrations). 

Key value for chemical safety assessment

Additional information

The toxicity of the substance to bacteria was assessed in a study according to ISO 8192 "Test for Inhibition of Oxygen Consumption of Activated Sludge". The substance showed no significant respiration inhibition of activated sludge at the highest concentration tested, and hence the IC50 is > 100 mg/L (based on nominal concentrations).
