Results and discussion
% Degradation
- Parameter:
- % degradation (DOC removal)
- Value:
- 5
- Sampling time:
- 28 d
- Details on results:
- The degree of biodegradation reached 5 % after 28 days.
No 10-day-window could be detected.

NA
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The test item must be considered as “not readily biodegradable“.
- Executive summary:
No degradation surpassing 10% was found during the test.
Therefore MDA must be classified as not readily biodegradable following OECD 301E resp. EU C.4-B.
