Description of key information

EC50 > 1500 mg/L

Key value for chemical safety assessment

EC50 for microorganisms:
1 500 mg/L

Additional information

The substance was tested for toxicity to microorganisms following OECD 209. The activated sludge was exposed at nominal concentrations of 62.5, 125, 250, 500, 1000 and 2000 mg/L. The respiration rate of each mixture was determined after aeration periods of 3 hours. The EC50 is higher than 1500 mg/L on the active ingredient. The effective value is related to nominal concentration, since no analytical monitoring was performed.
