- Preliminary purification step (if any):
none - Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Details on inoculum:
- - Source of inoculum/activated sludge (e.g. location, sampling depth, contamination history, procedure):
Brazos Valley River Sewer South - Duration of test (contact time):
- 28 d
- Initial conc.:
- 2 mg/L
- Based on:
- test mat.
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- This study was conducted to measure the biodegradability of the test substance, Hexatran-100, in an aerobic, aqueous medium at a concentration of approximately 2 mg/L of the test substance, as received. The solutions were prepared using inoculated mineral media with secondary effluent. The solutions were kept in closed bottles in the dark at 20°C. The degradation was measured by dissolved oxygen analyses over a 28-day period. A standard reagent of known performance (distilled aniline) and a blank were tested at the same time to serve as a control for biological activity.
- Reference substance:
- aniline
- Parameter:
- % degradation (O2 consumption)
- Value:
- -10.2
- Sampling time:
- 28 d
- Parameter:
- % degradation (O2 consumption)
- Value:
- -2.9
- Sampling time:
- 21 d
- Parameter:

- Value:
- 2.5
- Sampling time:
- 14 d
- Parameter:
- % degradation (O2 consumption)
- Value:
- -4.3
- Sampling time:
- 7 d
- Results with reference substance:
- day 7: 83.5%
day 14: 90.0%
day 21: 96.4%
day28: 86.2% - Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- Test substance is considered not biodegradable at 2 mg/L
- Executive summary:
For test substance, Hexatran-100, at 2 mg/L, values of -4.3%, 2.5%, -2.9% and -10.2% biodegradation was obtained on Days 7, 14, 21 and 28; therefore, the test substance is considered not biodegradable at 2 mg/L.
Reference
The dissolved oxygen (DO) readings and biodegradation calculations for the blank, the distilled aniline reference standard, and for the test substance are presented in Tables 1 and 2. The toxicity reference standard showed sufficient oxygen depletion, indicating that the test substance and reference materials were not toxic to the microbes in the activated sludge.
