Description of key information

The test substance is not harmful to activated sludge. The EC50 lies above 10000 mg/L

Key value for chemical safety assessment

EC50 for microorganisms:
10 000 mg/L
EC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

The activated sludge was exposed to test substance at different concentrations. The respiration rate of each mixture was determined after aeration periods of 3 h. Test substance showed 6.9 % respiration inhibition of activated sludge at a concentration of 10000 mg/L. The EC50 was determined to be > 10000 mg/L.
