Description of key information
The key value for this endpoint is provided by Barthel's study (2013). Inhibition respiration study on activated sludge shows a 180 min-NOEC equal or greater than 1000 mg of test item/L. So, the 180 min-EC10, EC20 and EC50 are greater than 1000 mg of test item/L.
This key value is valid for static and with aeration conditions.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The NOEC of test item is equal or greater than 1000 mg/L. The study don't let to affirm NOEC is strictly equal to 1000 mg/L.
