- Conclusions:
- Lithium bis(oxalato)borate was ready biodegradable under the conditions in the closed bottle test and therefore considered to be "ready biodegradable".
- Executive summary:
A study on biodegradation (closed bottle test) of lithium bis(oxalato)borate was assessed according to OECD guideline 301D and EU method C.4. The relative biodegradation values calculated from the 2 measurements performed during the test period of 28 days revealed 95 % degradation of test substance at 10 mg/L and 86 % degradation of test substance at 30 mg/L. Furthermore, at least 60 % degradation was reached within the 10 days immediately following the attainment of 10 % biodegradation (10-day window). Except for a deviating difference of duplicate values of the reference substance at the end of the test (24 %), which was considered not to have affected the integrity of this study, all criteria for acceptability of the test were met. Therefore, this study was considered to be valid.
Thus, lithium bis(oxalato)borate was ready biodegradable under the conditions in the closed bottle test. (NOTOX, 2004)
Reference
There was no inhibition of microbial activity in the toxicity control.
There was no significant degradation in the abiotic control.
Description of key information
Lithium bis(oxalato)borate was ready biodegradable under the conditions in the closed bottle test and therefore classified as "ready biodegradable".
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Key study:
The screening test on biodegradation in water (closed bottle test) according to OECD guideline 301D revealed a ready biodegradation for lithium bis(oxalato)borate. At least 60 % degradation was reached within the 10 days immediately following the attainment of 10 % biodegradation (10-day window). Except for a deviating difference of duplicate values of the reference substance at the end of the test (24 %), which was considered not to have affected the integrity of this study, all criteria for acceptability of the test were met. Therefore, this study was considered to be valid.
Supporting study:
The test substance lithium bis(oxalato)borate was found to be readily degradable under the present test conditions according to OECD guideline 301D. The abiotic degradation was the main cause of readily degradation in this study. However, another study confirms the ready biodegradability of Lithium bis(oxalato)borate through an biotic mechanism (key study: Notox, 2004).
