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:
- 22 March to 19 April 1991
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- Although a GLP compliant study, a reference substance of known biodegradability was not tested in parallel to check the test procedure and viability of the inoculum. However, a number of other test items were tested in parallel which did achieve the pass level of > 60%. Thus the study can be considered reliable with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)
- Deviations:
- yes
- Remarks:
- modified by use of sealed vessels for assessment of volatile substances
- GLP compliance:
- yes (incl. QA statement)
- Oxygen conditions:
- anaerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Details on inoculum:
- Secondary effluent from an unacclimatised activated sludge plant at URL North.
- Duration of test (contact time):
- 28 d
- Initial conc.:
- 10 mg/L
- Based on:
- other: Organic carbon
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Key result
- Parameter:
- % degradation (inorg. C analysis)
- Value:
- 87.7
- Sampling time:
- 28 d
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The Dihydromyrcenyl Acetate achieved 87.7% biodegradation in 28 days (i.e. 87.7%) and passed the 10d window (11.9% day 4, 67.2% day 14). Thus concluded as readily biodegradable.
- Executive summary:
The Dihydromyrcenyl Acetate achieved 87.7% biodegradation in 28 days (i.e. 87.7%) and passed 10d window (11.9% day 4, 67.2% day 14). Thus it can be concluded that the dihydromyrcenyl acetate is readily biodegradable according to this test (modified OECD guideline 301B using sealed vessels).

Description of key information
The Dihydromyrcenyl Acetate achieved 87.7% biodegradation in 28 days (i.e. 87.7%) and passed 10d window (11.9% day 4, 67.2% day 14). Thus it can be concluded that the dihydromyrcenyl acetate is readily biodegradable according to this test (modified OECD guideline 301B using sealed vessels).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
