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 Oxygen Consumption was tested in a Activated Sludge Respiration Inhibition Test according to OECD 209 and GLP (BASF SE 2014). After 3 h incubation no effects on the respiration rate have been observed. Therefore, the EC10 and EC50 were determined to be above 1000 mg/L.
