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 readily biodegradable under conditions of the test.

Since the test substance was found to be poorly biodegradable in an OECD 301B study it is assumed that the results of simulation studies would not reveal any different findings. Therefore, simulation studies in water/sediment and soil are not provided.
