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:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I))
- Deviations:
- yes
- Remarks:
- The method was modified according to EG ring test: Assessment of Biodegradability of Chemicals in Water by manometric Respirometry (DG X 1 283/82 Rev. 5)
- Principles of method if other than guideline:
- A measured volume of mineral medium, containing a known concentration of the test chemical (dissolved or suspended), is stirred in a closed flask with adapted activated sludge at a constant temperature (20 +/-1°C) for up to 28 days. The amount of oxygen taken up by the test chemical (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of theoretical oxygen demand (ThOD) or chemical oxygen demand (COD).
- GLP compliance:
- yes
- Remarks:
- This test was performed according to OECD guideline for GLP, with the exception of determination of stability, homogeneity and concentration of the substance in testing medium. Analysis was performed using nominal concentrations.
- Specific details on test material used for the study:
- Purity: 100%
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Details on inoculum:
- Origin: 10L from laboratory plant (Wupperverband)
Sampling: 10.01.1990
Pre-treatment: no
Concentration of inoculum: 30 mg/l (dry substance) - Duration of test (contact time):
- 28 d
- Initial conc.:
- 100 mg/L
- Based on:
- test mat.
- Parameter followed for biodegradation estimation:
- O2 consumption
- Reference substance:
- aniline
- Key result
- Parameter:
- other: Biodegradation in %
- Value:
- 0
- Sampling time:
- 28 d
- Remarks on result:
- other: Not readily biodegradable
- Parameter:
- ThOD
- Value:
- 1 921 mg O2/g test mat.
- Results with reference substance:
- The reference substance aniline showed a degradation of 69% using the same inoculum.
- Validity criteria fulfilled:
- yes
- Remarks:
- Determined result is valid, as the reference substance aniline showed a degradation of 69% using same inoculum. Inspection of test, raw data and report were controlled by the quality assurance at times.
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- Vulkacit P extra N shows a biodegradation of 0% and is therefore not readily biodegradable.
- Executive summary:
Vulkacit P extra N is analysed under GLP conditions according to MITI-Test (OECD guideline 301 C) in closed bottle under aerobic conditions. Measured theoretical oxygen demand of 100 mg/L test substance is 1921 mg/g. Determined biodegradation of Vulkacit P extra N is 0% after 28 days, it is therefore not readily biodegradable.
