- Experimental Methods
Biological oxygen demand (BOD) which occurred by the degradation of the test substance in the presence of the standard activated sludge was measured periodically (28 days) with the enclosed respirometer. After the last measurement of BOD, the concentration of the test substance was determined with LC/MS/MS and AA. And then the biodegradability of the test substance was evaluated from the results of the BOD and the concentration of the test substance.

Experimental Design and Additi on of the Test Substance
Bottle No. 1 : [Water + Test substance] system
Deionized water (300 ml) was transferred into a bottle and then the test substance (30 mg) was added to the water.
Bottle No. 2-No. 4: [Sludge + Test substance] system
Mineral medium* (297.1 ml) was transferred into 3 bottles each and then 30 mg of the test substance was added into each bottle, followed by the addition of the standard activated sludge** (2.9 ml) to each bottle.
Bottle No. 5: [Sludge + Aniline] system
Mineral medium* (297.1 ml) was transferred into a bottle and then 29 μL (30 mg) of aniline was added into the bottle with a micropipette. After mixing it well, the standard activated sludge** (2.9 ml) was added to the bottle.
Bottle No. 6: [Sludge blank] system
Mineral medium* (297.1 ml) was transferred into a bottle and the standard activated sludge** (2.9ml) was added to the medium.
*) A, B, C and D solutions (each 6 ml) were added to deionized water to make a 2-L solution.

- Observation Results of the Contents
The test solutions of the [Sludge + Test substance] system ( Bottle Nos. 2 - 4) and the [Sludge blank] system (Bottle No. 6) were slightly muddy white. The test solution of the [Sludge + Aniline] system (Bottle No. 5) was muddy white and that of the [Water + Test substance] system (Bottle No. 1) was colorless and transparent. The multiplication of activated sludge was observed in the [sludge + aniline] system only.
Degradability Based on the BOD Measurement
The BOD values after 28 days for the [Sludge + Test substance] system were 1. 9380 mg for bottle No. 2, 2.0440 mg for bottle No. 3 and 1.9960 mg for bottle No. 4. The BOD values
for the [Sludge blank] and [Water + Test substance] systems were 1.7450 mg and 0.0000 mg, respectively. Since the TOD of the test substance was 10.3 mg, the BOD degradabilities of the [Sludge + Test substance] system were 2% for bottle No. 2, 3% for bottle No.3 and 2% for bottle No. 4. Therefore, the mean degradability was calculated to be 2% . The difference of the degradation rates between maximum and minimum was less than 20% so the validity criterion of the biodegradation test was fulfilled.
Degradability Based on the LC/MS/MS Measurement
The amounts of the residual test substance in the [Sludge + Test substance] system were 31.1 mg for bottle No. 2, 29.5 mg for bottle No. 3 and 30.9 mg for bottle No. 4. The amount
of the residual test substance in the [Water + Test substance] system was 30.4 mg. The degradation rates of the [Sludge + Test substance] system were -2% for bottle No. 2, 3% for bottle No. 3 and -2% for bottle No. 4. Therefore, the mean degradability was calculated as 0%. The difference of the degradation rates between maximum and minimum was less than 20% so the validity criterion of the biodegradation test was fulfilled. No unknown peak which had larger area than the LOQ was observed on the LC/MS/MS chromatogram of the [Sludge + Test substance] system.
Degradability Based on the AA Measurement
The amounts of the residual lithium in the [Sludge + Test substance] system were 1.13 mg for bottle No. 2, 1.09 mg for bottle No.3 and 1.12 mg for bottle No. 4. The amount of the residual lithium in the [Water + Test substance] system was 1.07 m g . The degradation rates of the [Sludge + Test substance] system were -6% for bottle No. 2, -2% for bottle No. 3 and - 5% for bottle No. 4. Therefore, the mean degradability was calculated as -4%. The difference of the degradation rates between maximum and minimum was less than 20% so the validity criterion of the biodegradation test was fulfilled.

- Confirmation of the Degradation Activity of the Activated Sludge
The BOD degradabilities of aniline were 51% (7 days after the exposure) and 65% (14 days after the exposure). Therefore, it was considered that the activated sludge had good activity. Thus, the validity of this study was confirmed.

Results of the pH Measurement
At the start of the cultivation, the pH values of the [Water + Test substance] system, the [Sludge + Test substance] system, the [Sludge + Aniline] system and the [Sludge blank] system solutions were 5.3, 7.3, 7.3 and 7.3, respectively. At the end of the cultivation, the pH values of each system solution were 6.4, 7.3 (mean value), 8.4 and 7.7, respectively.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The biodegradation test of Lithium Bis(fluorosulfonyl) lmide (28 days) was conducted. The mean BOD degradability was 2% (n=3). The mean degradabilities calculated from the results of the LC/MS/MS and AA measurements were 0% (n=3) and -4% (n=3), respectively. Therefore, it was considered that Lithium Bis(fluorosulfonyl) lmide is not ready biodegradable because the degradabilities for all vessels were less than 60% (Test Methods and Judgment Criteria for the Designation of Monitoring Chemical Substances, April 12, 2010).
- Executive summary:
The biodegradation test (28 days) of Lithium Bis(fluorosulfonyl) lmide was conducted and the mean degradability calculated from the biological oxygen demand (BOD) was 2% (n=3). Furthermore, the mean degradabilities calculated from the residual amount of the test substance obtained by measurement with the liquid chromatograph mass spectrometer and the atomic absorption spectrophotometer were 0% (n=3) and -4% (n=3), respectively. It was considered that Lithium Bis(fluorosulfonyl) lmide is not ready biodegradable because the degradabilities for all vessels were less than 60% (Test Methods and Judgment Criteria for the Designation of Monitoring Chemical Substances, April 12, 2010).
