The ready biodegradability of the test item was determined in an OECD301F Test with a non-adapted activated sludge over a period of 28 days. The test item was tested at a concentration of 152 mg/L. The biodegradation of the test item was followed by determination of O2 consumption.

In order to check the activity of the test system a reference substance was tested. After 10 days a biodegradation rate of >60% % was reached.

The biodegradation remained in the range of 0 -5 % and the level of 60 % was not reached within the test duration of 28 days.

According to the criteria of the OECD 301F guideline the test item is not readily biodegradable within 28 days.
