- EC Number:
- 700-129-9
- Cas Number:

Constituent 1
Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, adapted
- Details on inoculum:
- A mixed population of sewage sludge micro-organisms was obtained from the final effluent stage of the Severn Trent Water Plc sewage treatment plant at Loughborough, Leicestershire, UK, which treats predominantly domestic sludge.
- Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 100 mg/L
- Based on:
- test mat.
Parameter followed for biodegradation estimationopen allclose all
- Parameter followed for biodegradation estimation:
- O2 consumption
- Parameter followed for biodegradation estimation:
- DOC removal
- Details on study design:
- The degredation of the test material was assessed by the measurement of daily oxygen consumption values and Dissolved Organic Carbon analysis on Days 0 to 28. Control solutions with inoculum and the standard material, aniline, together with a toxicity control were used for validation purposes.
Reference substance
- Reference substance:
- aniline
Results and discussion
% Degradation
- Parameter:
- % degradation (DOC removal)
- Value:
- 3
- Sampling time:
- 28 d
- Details on results:
- Samples for analysis were taken daily from the prepared test solutions.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not inherently biodegradable
- Executive summary:
The test material attained 3% degredation after 28 days and therefore cannot be considered as readily biodegradable under the strict terms and conditions of OECD Guideline No 301F.
