Description of key information
The effect of Cyclobutanate on the respiration rate of activated sewage sludge was investigated in a test according to OECD TG 209 under GLP. Validity criteria for the test were met. The effect of the test material on the respiration of activated sewage sludge gave a 3-hour EC50 of >= 1000 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was >=1000 mg/l.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
