Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 28
- Sampling time:
- 1 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The mean degradation rate calculated as the average of the degradation rates in the tests vessels was 28%.
- Executive summary:
The % biodegradation of the test item was calculated based on the theoretical oxygen demand (ThOD) in two individual tests. Different levels of biochemical oxygen demand (BOD) were observed in different flask, however in no cases the pass level for ready biodegradability (at least 60% of the ThOD in a 10 day window within the 28 days of the test period) was reached.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
