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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Reliability rating was 1 because study was carried out under GLP and test method used was equivalent to OECD 301B test method. Also study was well-documented.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)
- GLP compliance:
- yes
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Duration of test (contact time):
- 28 d
- Initial conc.:
- 10 other: mg/L carbon for ThCO2
- Based on:
- other: mg carbon per L
- Initial conc.:
- 20 other: mg/L carbon for ThCO2
- Based on:
- other: mg carbon per L
- Parameter:
- % degradation (CO2 evolution)
- Value:
- 33.2
- Sampling time:
- 28 d
- Remarks on result:
- other: at 10 mg C/L conc
- Parameter:
- % degradation (CO2 evolution)
- Value:
- 28.9
- Sampling time:
- 28 d
- Remarks on result:
- other: at 20 mg C/L conc
- Details on results:
- % Aerobic Ready Biodegradation Results on Day 1, 3, 6, 10, 14, 21 , 28 days were respectively,
0, 0.4, 2.6, 6.4, 10.0, 23.7, 33.2% for the test material at 10 mg C/L
0.3, 0.9, 2.3, 6.0, 10.5, 22.0, 28.9% for the test material at 20 mg C/L
16.6, 56.2, 75.6, 79.5, 81.3, 83.4, 84.4% for sodium benzoate (positve control) at 20 mg C/L -
sodium pass 10-day window criterion and met readily biodegradable classification - Results with reference substance:
- Sodium benzoate, the reference positive control substance, was biodegraded to 84.4% in 28 days and passed the 10-day window criterion for readily biodegradability
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- inherently biodegradable
- Conclusions:
- The test substance was found to biodegrade in water to the extent of 28.9 to 33.2% in 28 days in a standard CO2 evolution test method (equivalent to OECD 301B test). It was not readily biodegradable. However, overall, it meets the OECD criteria of being classified as "inherently biodegradable."
- Executive summary:
The test substance was found to biodegrade in water to the extent of 28.9 to 33.2% in 28 days in a standard CO2 evolution test method (equivalent to OECD 301B test). It was not readily biodegradable. However, overall, it meets the OECD criteria of being classified as "inherently biodegradable."
