Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Details on inoculum:
- - Activated sludge taken from a sewage treatment plant treating predominately domestic waste.
- Source: The sludge was taken from the activation basin of the ESN (Stadtentsorgung Neustadt)sewage treatment plant, Im Altenschemel , NW-Lachen Speyerdorf.
- The sludge was filtered washed with tap water twice, then washed and re-suspended in test medium. It was then aerated for > 12 hours. The dry matter was determined with 4540 mg suspended solids/L. - Duration of test (contact time):
- ca. 28 d
Initial test substance concentration
- Initial conc.:
- ca. 137 mg/L
- Based on:
- DOC
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Details on study design:
- See table in 'Any other information on materials and methods incl. tables' for information on the test setup. Additionally to this, two procedural control flasks (containing media only) and two controls (containing media and inoculum) were also included.
The test was aimed to be maintained at 19 - 20.5°C throughout (although measured as slightly lower than this, the validity criteria were met and as such this deviation is considered uncritical). A nominal starting concentration of 20 mg organic carbon/L was applied.
All test vessels were aerated with purified, CO2-scrubbed, moistened air. The scrubbing of carbon dioxide was achieved by bubbling the purified air through a flask containing 1.5 m-NaOH. To control the absence of CO2, the air was then led through a flask containing a solution of Ba(OH)2 before reaching the test vessels. Magnetic stirrers were used to prevent deposition of inoculum. The emitting CO2 was trapped 0.25-m-NaOH. Two scrubbers containing 100 mL each were connected in series to the test vessels.
Reference substance
- Reference substance:
- aniline
Results and discussion
- Test performance:
- From the biodegradation based on DOC (< 1%), it can be concluded that the test substance is not readily biodegradable.
% Degradation
- Parameter:
- % degradation (CO2 evolution)
- Value:
- < 1
- Sampling time:
- 28 d
BOD5 / COD results
- Results with reference substance:
- The positive control vessels (vessels containing the reference substance aniline) were greater than 60% by the end of the test (mean value of 84% by the end of the test). As such, the activity of the sludge was shown to be satisfactory.
Degradation in the toxicity flask was >25% by Day 14 and 34.6% by the end of the test indicating test validity.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- It is concluded that the test substance was not readily biodegradable under the conditions of the test.
