Results and discussion
% Degradation
- Parameter:
- % degradation (CO2 evolution)
- Value:
- < 10
- Sampling time:
- 28 d
- Details on results:
- The mean biodegradation after 28 days was 2%.
Any other information on results incl. tables
The mean biodegradation after 28 days was 2%.
The test item is classified as not readily biodegradable in the 10 -d-window and after 28 days.
In the inoculum control the total CO2 production was 32.2 mg CO2/L after 28 days (validity criterion: <40 mg CO2/L after 28days).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- The test item is classified as not readily biodegradable in the 10 -d-window and after 28 days.
