- inherently biodegradable
Additional information
The ready biodegradability of the test
item was assessed over a 28 day period by the modified Sturm test (OECD
301B). The nominal test concentrations were 10 and 20 mg a.s./L. The
test material attained up to 11 and 7 % biodegradation after 28 days
whereas the positive control substance (Aniline) was 94.4 % degraded 28
days. These results indicate that the test item cannot be classified
readily biodegradable under conditions of the test.
The inherent biodegradability of the test item was assessed over a 28
day period by the modified Zahn-Wellens Test (OECD 302B). The nominal
test concentrations was 10 mg a.s./L. The test material attained up to
60 % biodegradation after 28 days whereas the positive control substance
was 100 % degraded after 27 hours. These results indicate that the test
substance is inherently biodegradable in this test when measured by
specific analysis.
