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
- Study period:
- 1989
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Justification for type of information:
- The reported study is conducted with the analogue substance Alkaterge-T, which s made by condensing trometamol and Tall Oil Fatty Acids. Altalaterge E is made by condensing AEPD and Tall Oil Fatty Acids
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 D (Ready Biodegradability: Closed Bottle Test)
- GLP compliance:
- no
- Specific details on test material used for the study:
- C-14 labelled test material was used in the study
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Details on inoculum:
- The substance solution was inoculated with a few drops of inoculum from the discharge of a community water treatment plant. This completed test solution was distributed into the test vessels in exactly determined volumes so that duplicate samples were available for the determination of the O2 content. In addition, a corresponding number of test vessels were set up with nutrient solution, with nutrient solution + inoculum and a comparison substance.
- Duration of test (contact time):
- 28 d
- Initial conc.:
- 2 mg/L
- Based on:
- test mat.
- Details on study design:
- The chemical to be investigated was dissolved in a concentration of approximately 2 mg/L in a mineral nutrient medium. The latter was prepared from aerated deionized water (9 mg of 02/L) and from the corresponding nutrient salt and trace element stock solutions. The substance solution was inoculated with a few drops of inoculum from the discharge of a community water treatment plant. This completed test solution was distributed into the test vessels in exactly determined volumes so that duplicate samples were available for the determination of the O2 content. In addition, a corresponding number of test vessels were set up with nutrient solution, with nutrient solution + inoculum and a comparison substance. The test bottles were stored in the dark at 20-21°C and the oxygen content was determined on day 0 (beginning), day 5, day 15, day 28 (end) using an oxygen electrode. From the particular O2 content of the nutrient solution, the nutrient solution with inoculum and the test substance solution, the oxygen demand was determined for the test substance. From this, one was able to calculate the theoretical oxygen demand of biodegradation in %.
Dt = mg of BODx / L * 100 dvided by mg of substance / L * TOB
Dt = biodegradation in % of the test substance
BODx = biological oxygen consumption after x days
TOB = theoretical oxygen consumption - Reference substance:
- acetic acid, sodium salt
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- 32
- Sampling time:
- 28 d
- Remarks on result:
- other: not readily biodegradable
- Key result
- Parameter:
- BOD5
- Value:
- 0.9 mg O2/g test mat.
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The test substance is not readily biodegradable in the closed bottle test.
- Executive summary:
The test substance is not readily biodegradable in the closed bottle test.
Reference
