Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations. No toxic effects occur at the range of solubility

Key value for chemical safety assessment

Additional information

The inhibitory effect of the test substance on aerobic wastewater bacteria of activated sludge was investigated in a respiration test according to OECD guideline 209.

No significant ihnibition in respiration rate of the suldge was observed up to the highest concentration of 100.1 mg/L. The test substance is not toxic to wastewater bacteria. EC50 (30 min) is higher than 100 mg/L.
