Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 79
- Sampling time:
- 28 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Executive summary:
Nor Radjanol undergoes 79% biodegradation after 28 days in the test conditions. The 10 -day window criterion is also fulfilled (13% biodegradation on day 7 and 69% on day 17).
Nor Radjanol did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration.
Thus, Nor Radjanol should be regarded as readily biodegradable according to this test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
