Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
EC10 (3h) 420 mg/L (nominal) for activated sludge (OECD 209)

Key value for chemical safety assessment

Additional information

The toxicity to microorganisms was determined in a GLP Respiration Inhibition Test according to the OECD guideline 209 using domestic activated sludge. After 3 h of exposure the EC10 was 420 mg/L based on nominal concentrations [BASF SE, 2012].
