Description of key information

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

Key value for chemical safety assessment

Additional information

The changes in the respiration rate of activated sludge in presence of the test substance were investigated in three guideline studies according to OECD 209 and ISO 8192, respectively, with activated sludge as inoculum. At test termination after 30 minutes effect concentrations > 1000 mg/L (nominal) were determined [BASF AG 1998].
