Description of key information

With the duplicate samples of an activated sludge respiration inhibition test according to OECD 209 at a loading rate of 100 mg/L of the submission substance either no or 12% inhibition of respiration was observed. 
EC50 > 100 mg/L

Key value for chemical safety assessment

Additional information

Microorganism toxicity was determined by an activated sludge respiration inhibition test according to OECD 209 and EU-method C.11 (GLP-compliance). Tthe EC50 of the submission substance exceeded the nominal concentration (loading rate) of 100 mg/L. With the duplicate samples no and 12 % inhibition of respiration rate was observed.

Effect concentration:

EC50 >100 mg/L nominal concentration.
