Description of key information

Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge is not expected.

Key value for chemical safety assessment

EC50 for microorganisms:
230 mg/L
EC10 or NOEC for microorganisms:
40 mg/L

Additional information

One activated sludge respiration inhibition test according to OECD guideline 209 (Janssen, 1989) is available for the test substance.

The 3-h EC50 is 230 mg/L and the EC10 is 40 mg/L. Additionally several biodegradation studies exhibit the readily biodegradability of the test substance.

Therefore, depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge is not anticipated.
