Results and discussion
% Degradation
- Parameter:
- % degradation (O2 consumption)
- Value:
- 54
- Sampling time:
- 28 d
- Remarks on result:
- other: 10 d window failed
- Details on results:
- - The oxygen demand of the inoculum control (medium and inoculum) was 30 mg O2/L and thus not greater than 60 mg 02/L within 28 d.
- The difference of the duplicate values for the degradation of the test item and the plateau, at the end of the test and at the end of the 10 d window, was less than 20%
- The test item contains little amounts of nitrogen, therefore the evaluation of biodegradation has to be based on the assumption that nitrification occurred and expressed as ThODNO3.
However, the nitrate concentration in the test item treated vessels was below limit of quantification (LOQ). Therefore, no nitrification occurred.
If no nitrification is considered, the mean biodegradation was also 65% after 28 days of incubation (ThODNH4), still failing the 10-d window.
BOD5 / COD results
- Results with reference substance:
- The reference substance sodium benzoate was sufficiently degraded to 87% after 14 d and to 90% after 28 d of incubation, thus confirming the suitability of the aerobic activated sludge inoculum used.
Any other information on results incl. tables
None.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- inherently biodegradable
- Conclusions:
- Under the test conditions, the test substanc degraded by 54% within 28 days and was therefore not considered to be readily biodegradable. However an inherent potential for biodegradation was evidenced.
- Executive summary:
A study was conducted to determine the ready biodegradability of 'soybean oil, deodorizer distillates' according to OECD Guideline No. 301F and EU Method C4 -D.
The test substance was exposed to aerobic activated sludge from the aeration tank of a domestic waste water treatment plant for 28 d. The biodegradation was followed by the oxygen uptake of the micro organisms during exposure. As a reference item sodium benzoate was tested simultaneously under the same conditions as the test item, and functioned as a procedure control.
Considering that the test substance contains little nitrogen, the nitrate concentration was measured. However, the nitrate concentration in the test item treated vessels was below LOQ. Therefore, no nitrification occurred.
The reference substance was degraded to more than 60% after 3 d of incubation.
Under the test conditions, the test substanc degraded by 54% within 28 days and was therefore not considered to be readily biodegradable. However an inherent potential for biodegradation was evidenced.
