Results and discussion
% Degradation
- Parameter:
- % degradation (O2 consumption)
- Value:
- 0
- Sampling time:
- 48 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Executive summary:
Cyclogeranitrile Beta undergoes no biodegradation after 28 days (no biodegradation after 48 days) in the test conditions.
Cyclogeranitrile Beta did not significantly inhibit the intrinsic respiration of the inoculum at the test concentratrion and was therefore considered to be non-toxic to the inoculum at the test concentration.
Thus, Cyclogeranitrile Beta should be regarded as not readily biodegradable according to this study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
