EC number: 203-652-6
CAS number: 109-16-0
ready 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.
test item proved to be readily biodegradable and fulfilling the 10-d
10-day window started on day 7. Biodegradation achieved 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%).
to Annex IX 22.214.171.124. Column 2, a study on biodegradation in water and
sediment does not need to be conducted as the substance is readily
biodegradable (experimental result please see chapter 5.2.1).
to Annex IX 126.96.36.199. Column 2, a study on biodegradation in soil does
not need to be conducted as the substance is readily biodegradable
(experimental result please see chapter 5.2.1.).
