- Test material form:
- other: viscous liqid
- Details on test material:
- Stabilized EMIM BF4:

Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Details on inoculum:
- Specification: Activated sludge from a biologic sewage treatment plant - mostly household sewage.
Source: activation basin, Stadtentsorgung Neustadt, Im Altenschemel, NW-Lachen-Speyerdorf
Date of collection: 26. Feb. 2015, batch no.: 20150226
Pre-Treatment: The sludge eas filtrated through a cloth, washed with tap water twice and with test medium once. The solids were the resuspended in
test medium and aerated. The dry matter was determined with 3720 mg suspended solids /L. - Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 53.1 mg/L
- Based on:
- DOC
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- inorg. C analysis
- Details on study design:
- This study was performed in order to evaluate the aerobe degradation potential of stabilized EMIM BF4 by aerobe micro-organisms at a given concentration.
The test item as the sole source of carbon and energy was incubated in a buffer-mineral salts medium which was inoculated with a mixed population of micro-organisms. The test was performed in sealed bottles with a headspace of air, which provides a reservoir of oxygen for aerobic biodegradation. The CO2 evolution resulting from the readily aerobic biodegradation of the test item was determined by measuring the IC produced in the test bottles in excess of that produced in blank control vessels containing inoculated medium only. The extent of biodegradation was expressed as a percentage of the theoretical maximum IC production (ThIC), based on the quantity of test item (as organic carbon) added initially.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The test item must be classified as "not readily biodegradeable"
- Executive summary:
The test item was tested using a concentration of 53.1 mg stabilized EMIM BF4/L in test medium following ISO 14593:205.
Aniline was chosen as positive control.
Activated sludge from a sewage treating plant was used as inoculum (concentration: 4 mg suspended solids/L). The test was left running for 28 days.
All validity criteria were met. Degradation of the positive control was 68 % after eight days.
The following data were determined for the test item stabilized EMIM BF4:
10 -day-window: not detectable
degradation at the end of the test: 1.8 %
Therefore, stabilized EMIM BF4 is not readily biodegradeable following OECD 310.
