Description of key information

The influence of the substance on the respiration rate of activated sludge was investigated in a 3-h study in accordance with OECD TG 209 and in compliance with GLP. Concentration-related inhibition of respiration rates was observed at concentrations between 30 and 300 mg/L, with concentrations of 1000 and 3000 mg/L showing 67 % inhibition. The 3-h EC50 was calculated to be 241 mg/L (95 % confidence limits 55 - 1150 mg/L). The data did not permit the accurate calculation of the EC20 and EC80 values or their confidence intervals.

Key value for chemical safety assessment

EC50 for microorganisms:
241 mg/L
