Additional information

The ready biodegradation of the substance under the conditions of the closed bottle test was investigated according to OECD guideline 301 D. A test concentration of 2 mg/L was tested in duplicate during 28 days. The relative biodegradation values calculated from the O2 measurements performed during the test period of 28 days revealed no significant biodegradation of the substance. After 5, 15 and 28 days, 0, 3 en 2% biodegradation, respectively. The criteria for acceptability of the test were met. The substance was therefore determined to be not readily biodegradable under the conditions of this study. A toxicity control was not tested.
