BIS TRIFLUOROMETHANE SULFONIMIDE LITHIUM; FLUORAD BRAND LITHIUM TRIFLUOROMETHANESULPHONIMIDE HQ-115
Bioconcentration factors <41 (test concentration 0.225 µg/mL) and <4 (test concentration 2.56 µg/mL) were observed.
A bioconcentration study of Bis
trifluoromethanesulfonimide lithium (TFSILi) was performed in accordance
with the OECD 305 guideline and under GLP conditions. After an acute
toxicity study, doses of 0.25 and 2.5 µg/ml were selected to treat
Cyprinus carpio fish under continuous flow through system, during 8
weeks. HPLC method was used to determine concentration of test item in
water and in fish. The detection limit for bioconcentration was 4 for
the high exposure level and 40 for the low exposure level. The
mean concentrations of the test substance during the exposure period of
8 weeks were 2.56 µg/mL for high exposure level and 0.225 µg/mL for low
exposure level, which almost corresponded to the nominal values. The
coefficients of variation were calculated to be 6.6% for high exposure
level and 7.5% for low exposure level.
The concentrations of the test substance in
fish were calculated to be below 9.6 µg/g at high exposure level and
below 9.2 µg/g at low exposure level. The bioconcentration factors
(BCFs) were determined to be below 4 for high exposure level and below
41 for low exposure level.
On the basis of the above results, it was
concluded that the test substance was not bioaccumulative in carp under
the prescribed test conditions.
