Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 April to 6 June 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Data have been generated according to current internationally recognised study guidelines and in accordance with GLP.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I))
- GLP compliance:
- yes (incl. QA statement)
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- mixture of sewage, soil and natural water
- Duration of test (contact time):
- 28 d
- Initial conc.:
- 100 mg/L
- Based on:
- test mat.
- Reference substance:
- aniline
- Parameter:
- other: BOD
- Value:
- 0
- Sampling time:
- 28 d
- Parameter:
- % degradation (DOC removal)
- Value:
- 4
- Sampling time:
- 28 d
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- Under the conditions of the ready biodegradation test, the substance is not readily biodegradable.
- Executive summary:
The ready biodegradation was assessed according to the OECD 301C MITI biodegradation test in compliance with GLP. The substance was assessed over a 28 -day exposure period in the presence of a standard sewage sludge inoculum alongside an aniline standard. The test substance achieved 0% biodegradation and no detected chemical change after 28 days. The substance is not readily biodegradable and is considered to be persistent in the aquatic environment.
