Ready Biodegradability of FAT 40858/A TE in a Manometric Respirometry TestInherent Biodegradability of FAT 40858/A TE in a Zahn-Wellens/EMPA Test
The criterion for ready biodegradability under the
conditions of a manometric respirometry test is the 10-day window,
describing the period between reaching at least 10% degradation and 60%
degradation. This period should not exceed 10 days.
The mean biodegradation after 28 days of FAT
40858/A TE was 0% (ThODNH4) and 0% (ThODNO3); the
10 day window criterion was not passed.
Therefore, FAT 40858/A TE is considered not to be
the test conditions no biodegradation (-164%) of FAT 40858/A TE occurred
after 28 days of incubation. Since the percentage biodegradation is not
within 20 - 70 % based on DOC, the test item can be estimated not to be
inherently biodegradable. Negative biodegradation values were calculated
due to total recovery of the DOC of the test material and also
additional DOC from the sludge inoculum showing absolute no
biodegradation by the sludge bacteria.
reference item Diethylene glycol was completely degraded to 102% after
14 days, and to 106% after 28 days of incubation, thus confirming the
suitability of the used activated sludge inoculum.
