Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 76
- Sampling time:
- 28 d
- Details on results:
- Anther undergoes 79% biodegradation after 34 days (76% after 28 days) in the test conditions. Biodegradation starts on day 7 and reaches 64% at the end of the 10 day window (day 7 to day 17).
At the concentration used in the test (100 mg/l), Anther is not inhibitory to the micro-organisms.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Anther should be regarded as readily biodegradable according to this test.
- Executive summary:
The Ready biodegradation of Anther was determined by the Manometric Respiratory test according to the OECD guideline for testing of chemicals, Method No. 301F.
Anther undergoes 79% biodegradation after 34 days (76% after 28 days) in the test conditions. Biodegradation starts on day 7 and reaches 64% at the end of the 10 day window (day 7 to day 17).
Anther should be regarded as readily biodegradable according to this test.
At the concentration used in the test (100 mg/l), Anther is not inhibitory to the micro-organisms.
