% Degradation
- Parameter:
- % degradation (O2 consumption)
- Value:
- 5
- Sampling time:
- 3 h
Any other information on results incl. tables
Biodegradation:
Degradation after 7 days was 99% (based on DOC).
In the Zahn-Wellens test, 5% degradation was observed after 3 hours. The concentration was 400 mg/L.
Therefore the substance is regarded to be readily biodegradable.
Applicant's summary and conclusion
- Interpretation of results:
- readily biodegradable
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
