Description of key information

Key study:- Hanstveit (2003), OECD 30-F and EU Method C.4-D (read-across from dioctyltin oxide); Not readily biodegradable, approximately 2 % biodegradation occurred within 28 days.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The data requirement was addressed by the key study as reported by Hanstveit (2003). The study was performed to GLP and in line with the OECD guideline 301-F and EU Method C.4-D. As the study was conducted with the read-across substance, dioctyltin oxide, the study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality by Klimisch (1997). The study was considered to be reliable with restrictions and adequate for assessment of the substance. Under the conditions of the study, approximately 2 % biodegradation of the test material during 28 days of incubation occurred, it can be concluded from the results of this study that the test material is not readily biodegradable.
