CAS number: 77-90-7
Results:a. OECD Guideline 302 C: 82% biodegradation after 28 d (inherently biodegradable) b. OECD Guideline 301 D: 16% biodegradation after 28 d (not readily biodegradable)b. OECD Guideline 302 C: 82% biodegradation after 28 d (inherently biodegradable)
inherent biodegradation of tributyl acetyl citrate was investigated in a
study conducted corresponding to OECD Guideline 302C: "Inherent
Biodegradabilty: Modified MITI Test (II)"over a period of 28 days and
using activated sludge as inoculum. The biodegradation rate was
determined by measurement of oxygen consumption. Inoculum blank and
procedural/functional control with the reference substance aniline were
performed.The test item proved to be inherently biodegradable under the
test conditions employed (82% biodegradation after 28 d). The functional
control reached the pass level >60% after 14 d.
biodegradation of tributyl acetyl citrate was investigated in a study
conducted according to EU Method C.4-E (Determination of the "Ready"
Biodegradability - Closed Bottle Test; 2008) and OECD Guideline 301 D
(Ready Biodegradability: Closed Bottle Test; 1992) over a period of 28
days and using a mixed inoculum composed of sewage from a sewage
treatment plant working predominantly on domestic sewage and soil. The
biodegradation rate was determined by measurement of oxygen consumption.
Inoculum blank, procedural/functional control with the reference
substance sodium benzoate, and toxicity control using 1.642 mg/L test
substance and 3.033 mg/L reference compound were performed. The test
item proved to be not readily biodegradable under the test conditions
employed (16% biodegradation after 28 d). The functional control reached
the pass level >60% after 14 d. In the toxicity control containing both
test and reference item 47% biodegradation based on ThOD occurred within
14 d thus indicating that the test item was not inhibitory at the
