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:
- 2016-03-19 till 2016-04-15
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- without GLP
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test)
- Version / remarks:
- adopted July 17, 1992
- GLP compliance:
- no
- Remarks:
- The substance is known to be not readily biodegradable. Therefore a non-GLP study was adequate to prove the poor biodegradability.
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Duration of test (contact time):
- 28 d
- Initial conc.:
- 41 mg/L
- Based on:
- test mat.
- Preliminary study:
- Result of the preliminary study:
The biodegradation of the test item (2 replicates) does not reach the 10 % level (beginning of biodegradation) until test end. The mean biodegradation on day 28 was 6 %. - Key result
- Parameter:
- other: BOD
- Value:
- ca. 6
- Sampling time:
- 28 d
- Remarks on result:
- other: not readily biodegradable
- Details on results:
- not readily biodegradable
- Results with reference substance:
- no reference substance used for limit test
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The test item is classified as not readily biodegradable within 28 days.
