Description of key information
Based on the results of two reliable biodegradation studies on the reaction mass of potassium trifluoroacetate and potassium trifluoromethanesulphinate, the test item is neither considered readily biodegradable nor inherently biodegradable.
Additional information
Two reliable biodegradation studies are available for the reaction mass of potassium trifluoroacetate and potassium trifluoromethanesulphinate.
The aerobic ready biodegradability of Reaction mass of potassium trifluoroacetate and potassium trifluoromethanesulphinate was investigated in a GLP-compliant study performed in accordance with OECD Guideline No. 301 F. The biodegradation was followed during 28 day, with an initial test substance concentration of 210 mg/L (corresponding to 50.4 mg ThOD/L) using a non-adapted inoculum. Dissolved oxygen consumption was measured continuously.
The mean total oxygen uptake in the inoculum blanks at the end of the test was < 60 mg O2/L. The biodegradation of the reference substance (sodium benzoate) reached the pass level of ready biodegradation test (>60% within 14 days). The degradation of the toxicity control after 14 days was >25%; the test item had no inhibitory effect on the inoculum according to the criterion of the guideline. Therefore the test is considered valid.
The biodegradation of the test item attained an average of 18% at Day 22 (10 -d window) and 22% at Day 28. Therefore the test item is not considered to be readily biodegradable under the experimental conditions.
In the other study, the inherent biodegradation of the test substance (reaction mass of potassium trifluoromethanesulphinate and potassium trifluoroacetate) was investigated according to the OECD Testing Guideline 302C : "Inherent Biodegradability: Modified MITI Test (II)” (1981). Test solutions were prepared in an inorganic salts medium, inoculated with a number of micro-organisms collected from 10 places in Nanjing city. During the test, the temperature was kept at (25±1)℃. The test was valid because the level of biodegradation of the reference substance sodium benzoate exceeded 40% after 7 days, and 65% after 14 days.
Based on the residue analysis, biodegradation of the test substance was less than 1% in the “test” vessel during the testing period. The BOD results showed that biodegradation of the test substance was less than 1% after 28 days.
Therefore, the test item is not inherently biodegradable under this test condition.
Based on the available data the reaction mass of TFAK/TFSK is not considered to be readily biodegradable nor inherently biodegradable.
