EC number: 607-813-5
CAS number: 25830-77-7
The O2 uptake values and degradation data
are summarized in the tables attached under the ''Attached background
The following validity criteria were
fulfilled and therefore the test was considered valid:
1. The difference of extremes of replicate
values of the removal of the test chemical at the plateau, at the end of
the 10-d window, or at the end of the test, as appropriate, must be less
than 20% - actual: 4% at the end of the 10 -d window (day 20) and 0% at
the end of the test (day 28)
2. The percentage of degradation of the
reference item must reach the pass level of 60% by day 14 - actual: 86%
by day 14
3. In the toxicity control, the degradation
of the mixture test item + reference item must reach the pass level of
25% by day 14; otherwise, the test item can be assumed to be inhibitory
and the test should be repeated using a lower concentration of test item
- actual: 62% by day 14
4. The O2 uptake in the blank control should
normally be 20-30 mg O2/L and should not be greater than 60 mg O2/L in
28 days. - actual: 19.6 mg O2/L
5. The pH value should be in the range of
6-8.5 - at the end of the test: pH blanks: 7.3; pH test item solution:
7.5 and 7.7; pH reference item solution: 7.6 and 7.5; pH toxicity
In a test perfomed according to OECD 301F
(Manometric Respirometry Test) and GLP, the test item biodegraded for
85% after 28 days. The pass level of 60% for ready biodegradability was
reached within the 10 day window after attaining 10% degradation. It can
therefore be termed as readily biodegradable.
