The readily biodegradability of the test
substance was investigated in a Manometric Respirometry Test over 55
days (Eisner, 2013). The experiment was conducted in accordance to OECD
Guideline 301 F, EU Method C.4‑D and US EPA Draft OPPTS 835.3110
(Paragraph (q)). The per cent biodegradation of the test item was
calculated based on the chemical oxygen demand of 1.54 mg O2/mg test
item. The biochemical oxygen demand (BOD) of 1,2,3-Propanetriol,
glycidyl ethers in the test media increased from test start until test
termination after 55 days. At Exposure Day 28 and at test end after 55
days, the mean biodegradation of 1,2,3-Propanetriol, glycidyl ethers
amounted to 13 % and 24 % of the COD, respectively. The pass level for
ready biodegradability, i.e. biodegradation of at least 60 % of the COD
in a 10‑day window within the 28‑day period of the test, was not
reached. In conclusion, the test substance is considered to be not
investigations concerning biodegradation in water and sediment
(simulation tests) and soil are intendedas
the result of the Chemical Safety Assessment indicates no need to
investigate further the degradation of the substance and its degradation
the substance does not bioaccumulate in the environment, which is shown
by the QSAR prediction for BCF (see bioaccumulation). In
accordance with REACH, Annex IX, Section 220.127.116.11 and Section 18.104.22.168,
column 2, no further testing is triggered for this endpoint.
