Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
IC20 (3h) > 100 mg/L (nominal) for activated sludge (OECD 209)

Key value for chemical safety assessment

Additional information

The influence on the respiration inhibition of microorganisms was investigated in a GLP guideline study according to OECD 209 [Ciba-Geigy Ltd., 2012]. The study was conducted with activated sludge from municipal sewage treatment plant, which predominantly receives domestic sewage. After 3 hours of exposure an IC20 of > 100 mg/L (nominal) was determined.
