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

No inhibition was observed in an activated sludge respiration inhibition test after an incubation time of 30 minutes [BASF AG, 1982]. At the highest test concentrations of 750 and 1995 mg/L a promotion of the respiration was determined.
