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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP compliant, guideline study, available as unpublished report, acceptable with restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)
- Deviations:
- not specified
- GLP compliance:
- yes
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Details on inoculum:
- non adapted domestic sludge obtained from the Marl-Ost municipal sewage plant. The bacterial count of the sewage was 72 X 104 CFU/ml. Aerated at 21.4°C (mean)
- Duration of test (contact time):
- 29 d
- Initial conc.:
- 21.4 mg/L
- Based on:
- test mat.
- Initial conc.:
- 21.5 mg/L
- Based on:
- test mat.
- Details on study design:
- Test vessels: approx. 5000ml Woulff Flasks.
- 2 vessels without the test item and with inoculum (blank batches)
- 1 vessel containing control item and inoculum (control batch)
- 2 vessels containing test item and inoculum (test item batches)
Carbon analysis performed by AS analysis division. C content 69.8%
TIC determined after 0, 2, 5, 8, 12, 19, 22, 28 and 29 days in duplicate. CO2 content measured via TIC analysis in a carbon analyser. - Reference substance:
- other: sodium benzoate
- Preliminary study:
- No data
- Test performance:
- No data
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- -6
- Sampling time:
- 28 d
- Details on results:
- Negative value for % degradation due to mathematical calculations.
- Results with reference substance:
- Degradation of the control item: 95% after 28 days and therefore the inoculum had a sufficient biological activity
- Validity criteria fulfilled:
- yes
- Remarks:
- Cumulative evolution of CO2 in the blank batch: 19.95mg/L (does not exceed 40 mg/L))
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- Tris(triphenylphosphine)rhodium(1)chloride is not biodegradable.
- Executive summary:
Biodegradation was assessed in a GLP-compliant study following OECD 301B (Enste-Diefenback 2016) using activated, non-adapted sludge. Test concentrations of 21.4 mg/L and 21.5 mg/L (test item), corresponding to 14.9 mg C/L and 15.0 mg C/L, respectively, were used. Blank controls and reference item controls were included in the study. The test item degraded by -6% over 28 days, the negative value is due to mathematical calculations. Tris(triphenylphosphine)rhodium(1)chloride is not biodegradable.
