- Inoculum or test system:
- other: mixed population of aquatic microorganisms
- Details on inoculum:
- Source: secondary effluent of a domestic sewage treatment plant (STP Odenthal, Germany)
Date of collection: 2000-01-21
Preconditioning: separation of coarse particles by filtration; aeration of mineral medium plus inoculum (filtrate) for 6 days
Effluent concentration in reaction mixture: 5 mL/L - Duration of test (contact time):
- 28 d
- Initial conc.:
- 4.1 mg/L
- Based on:
- test mat.
- Details on study design:
- Pretreatment of test substance:
The test substance was weighed out on aluminium foil. This substance inclusive the aluminium foil was added to the test vessel.
Exposure conditions:
Incubation time: 28 d
Incubation temperature: 20 - 21°C - Reference substance:
- benzoic acid, sodium salt
- Remarks:
- Purity: 99%; initial concentration: 2.9 mg/l
- Parameter:
- % degradation (O2 consumption)
- Value:
- 0
- Sampling time:
- 28 d
- Value:
- 1 703 mg O2/g test mat.
- Results with reference substance:
- 77 % degradation of benzoic acid, sodium salt within 14 days, and 81 % degradation within 28 days.
- Validity criteria fulfilled:
- yes
- Remarks:
- 77 % degradation of the reference compound benzoic acid, sodium salt within 14 days
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- With 0 % degradation within 28 days the substance is considered as not readily biodegradable.
- Executive summary:
Using the EU Method C.4-E (Determination of the "Ready" Biodegradability - Closed Bottle Test) 0 % degradation within 28 days was observed for the substance. Therefore, the substance is considered as not readily biodegradable.
Reference
