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:
- 1975
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- 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:
- activated sludge, non-adapted
- Details on inoculum:
- - Concentration of sludge: 30 ppm
- Duration of test (contact time):
- 2 wk
- Initial conc.:
- 100 other: ppm
- Based on:
- ThCO2
- Parameter followed for biodegradation estimation:
- O2 consumption
- Parameter followed for biodegradation estimation:
- TOC removal
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 0
- Sampling time:
- 14 d
- Key result
- Parameter:
- % degradation (TOC removal)
- Value:
- 0
- Sampling time:
- 14 d
- Remarks on result:
- other: negative value obtained
- Parameter:
- % degradation (test mat. analysis)
- Value:
- 6.2
- Sampling time:
- 14 d
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- No biodegradation of the test item was observed (0%) after 14 days. Therefore, the test item is not readily biodegradable.
- Executive summary:
A screening test of ready biodegradability of the test substance was performed according to the Japanese MITI test and OECD Guideline 301C. The substance, present at 100 ppm, reached 0% of its theoretical BOD in 2 weeks, using an activated sludge inoculum at 30 ppm. Therefore, the test item is not readily biodegradable.

Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- freshwater
