Description of key information

The substance does not inhibit the respiration of activated sludge at a concentration of 100 mg/l, under the conditions of the OECD test guideline 209. 

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

In an activated sludge respiratory inhibition test conducted according to the OECD 209 test guideline, no inhibition of respiration was detected at a concentration of 100 mg/L of test substance. The 3-h IC50 of the substance was > 1000 mg/L. The IC50 value is considered equivalent to an EC50 value for the purposes of risk assessment.
