% Degradation
- Parameter:
- % degradation (O2 consumption)
- Value:
- > 0 - < 3
- Sampling time:
- 28 d
- Details on results:
- The results showed the expected rapid degradation of acetate (complete within seven days). The measured oxygen consumption of acetate was 0.66 mg O2/mg after seven days and compared well with the theoretical oxygen demand of 0.68 mg O2/mg.
The calculated oxygen consumption of acetate in the presence of the test substance was slightly lower than found with acetate alone, indicating that Soltex had a slightly inhibiting effect on the acetate degradation.
The oxygen consumption due to the acetate in presence of the 3.5% bentonite slurry was similar to that of acetate and Soltex, confirming that the effect recorded above was probably caused by the bentonite slurry.
Soltex was not degraded in the presence of acetate.
BOD5 / COD results
- Results with reference substance:
- 0.63 mg oxygen consumption per mg sodium acetate.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- No oxygen consumption was found which could be attributed to the biological degradation of Soltex.
