Description of key information

The key study for biodegradability (Hanstveit, 2003) reported 0% degradation of the registered substance after 28 days and -3% after 39 days. The substance is therefore not considered readily biodegradable as the 60% degradation criterion after 28 days was not met. The oxygen consumption in the degradation test was inhibited by the test substance. Therefore, any biodegradability of tetraoctylstannane could not be demonstrated in this test due to its inhibiting effects to the inoculum.

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.
