EC number: 203-652-6
CAS number: 109-16-0
On day 28, 1 mL conc. HCl was added to each flask to stop
biodegradation and aerated overnight to drive off the remaining CO2. A
final CO2 analysis was made on day 29 being representative of
biodegradation of day 28.
- biodegradation values of the test substance do not deviate by
more than 20% at the end of the study
- biodegradation of the reference substance >60% after 14 days
- blank value <70 mg CO2/L at the end of the study
biodegradation of TREGDMA was investigated in a study conducted
according to OECD Guideline 301 B (CO2 evolution test), adopted 17th
July 1992, and EU Method C.4 -C, 31 July 1992, over a period of 28 days
using sewage sludge sampled from the aeration tank of a predominantly
domestic sewage treatment plant as inoculum. The biodegradation rate was
determined by measurement of CO2 evolution. Inoculum blank and
procedural/functional control with the reference substance sodium
acetate were performed.
item proved to be readily biodegradable and fulfilling the 10-d window
window started on day 7. Biodegradation totalled 61% at the end of the
10 day window (day 17) and 85% at the end of the test period. The
functional control reached the pass level >60% after 14 d (68.5%).
is regarded as reliable without restriction and satisfies the guideline
requirements for ready biodegradation. TREGDMA proved to be readily
biodegradable and fulfilling the 10-d window criterion.
