CAS number: 991-84-4
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 5 and 7 % biodegradation after 28 days
whereas the positive control substance (Aniline) was 93 % degraded after
28 days. These results indicate that the test item cannot be classified
readily biodegradable under conditions of the test.
The COD calculted in a study according
to DIN 38409 was determined to be 2.41 g COD/ g test item.
A simulation study in water and sediment is
not regarded as valid as it could not be clarified if the substance
degraded or merely bound to the sludge of the test system due to
test substance was found to be poorly biodegradable in an OECD 301B
study. It is assumed that the results of further simulation studies
would not reveal any different findings. Therefore, further simulation
studies in water/sediment and soil are not provided.
