Description of key information
The test substance is not harmful to activated sludge. The EC50 lies above 1000 mg/L
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
A study was conducted to assess the toxicity of the test substance to sludge microorganisms, according to Guideline 88/302/EEC, L 133 Part C (similar to OECD Guideline 209.
Activated sludge from domestic sewage was exposed to a nominal test substance concentration of 1000 mg/L for a period of 3 h. The respiration rate was determined after an aeration period of 3 h and compared to data from the control.
Under the test conditions, the EC50 of the test substance was > 1000 mg/L, indicating a low toxicity to microorganisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
