Description of key information

The substance can therefore be considered to be not readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Study rel.2, Müller, 1992:

Ready biodegradability of the substance was assessed according to EC method C.4.D fulfilling all validity criteria. Bacterial respiration was measured as theoretical oxygen demand and gave 21 % biodegradation within 28 days (positive control aniline: 80 % within 28 days). Test sample included 35 % solvent naphtha and observed biodegradation is expected to be that of the solvent. As a conclusion these results are considered to support the results of the respective key study.
