Description of key information

Benoxacor was shown not to be readily biodegradable, according to a study conducted under the conditions of an OECD 301F test.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The key study (Wallace, 2002) investigated the ready biodegradability of benoxacor (CGA154281) in water. This GLP-compliant study is considered to be reliable without restrictions. The ready biodegradability of benoxacor was determined using the OECD 301F method. Using activated sludge as the test inoculum, the percent biodegradation of benoxacor was less than 5% indicating that the material was not readily biodegradable. Reference substance (sodium acetate) incubated in the same sludge showed a percentage biodegradation between 68 and 78% showing that the test inoculum contained viable organisms.
