Description of key information

The test item showed 18.2 % respiration inhibition of activated sludge after a test period of 30 minutes at the highest concentration of 10000 mg/L. Therefore an EC50 of higher than 10000 mg/L could be calculated for the test substance. The effect value relates to a nominal concentration, since no analytical monitoring was performed.

Key value for chemical safety assessment

EC50 for microorganisms:
10 000 mg/L
