Results and discussion
% Degradation
- Parameter:
- % degradation (O2 consumption)
- Value:
- 65
- Sampling time:
- 28 d
- Remarks on result:
- other: 10 d window failed
- Details on results:
- - The 10 d window failed.
- 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
In the toxicity control containing the test item and the reference item sodium benzoate, 45% biodegradation was noted within 14 d and 51 % biodegradation after 28 d of incubation.
Thus, the test material can be assumed to be not inhibitory to the aerobic activated sludge micro organisms.
For more details on the results, see Table 1 - 5 and Figure 1 - 2 under the window 'attached background material'.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable, but failing 10-day window
- Conclusions:
- Under the test conditions, the test substance was considered to be readily biodegradable.
- Executive summary:
A study was conducted to determine the ready biodegradability of 'oils, vegetable, 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 substance was considered to be readily biodegradable, but failed the 10-d window.
