Description of key information

The biodegradabiliy of dioctyltin dichloride was examined in a manometric respirometry test, according to OECD 301 F. The mean biodegradation after 28 days was -3 % and the test substance could therefore not be classified as ready biodegradable. The study was extended to 39 days, for which the mean biodegradability was found to be -4 %.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A reliability rating of 1 was assigned to the key study, according to the criteria of Klimisch, 1997 as the study was conducted in accordance with recognised guidelines and GLP.
