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
Additional information
"should read > 10000 mg/L"
