The test substance is not readily biodegradable according to OECD criteria. It is poorly biodegradable.
The ready biodegradability of the test item was assessed over a 28 day
period by the modified Sturm test (OECD 301B, Ciba-Geigy Ltd. 1988). The
nominal test concentrations were 10 and 20 mg a.s./L. The test material
attained 0 % biodegradation after 28 days for both concentration levels
whereas the positive control substance (Aniline) was 94.4 % degraded 28
days. These results indicate that the test item cannot be classified as
readily biodegradable under conditions of the test.
