Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.

Key value for chemical safety assessment

Additional information

The inhibition of the degradation activity of activated sludge was evaluated in a study according to OECD 209 under consideration of GLP. Activated sludge was exposed with the test substance at a limit concentration of 1000 mg/L for 30 min. No effects could be recored. The EC50 value was determined to be >1000 mg/L.
