EC number: 213-590-1
CAS number: 991-84-4
Not readily biodegradable (according to OECD criteria); poorly biodegradable.
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.
