Constituent 1
Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 12 mg/L
- Based on:
- other: TOC
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- CO2 evolution
Results and discussion
% Degradation
- Parameter:
- % degradation (CO2 evolution)
- Value:
- < 5
- Sampling time:
- 28 d
- Details on results:
- In the toxicity control more than 25% degradation occurred within 14 days (based on ThC02). Therefore, the test substance was assumed to be not inhibitory.
Applicant's summary and conclusion
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The test substance was not readily biodegradable under the condition of the modified Sturm test presently performed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
