Description of key information

 Based on reliable data, the test substance is readily biodegradable and meet the 10-day window.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The test substance is highly volatile. Thus any test design should have used closed or sealed vessels. Two studies are available. Yet Berti (2001) used a modified Sturm test which is not suitable for volatile substances and thus has been disregarded. De Nadai (2009) on the opposite used a closed test system and followed inorganic carbon. This last study is extensively detailed and show 83% of biodegradation of the substance after 28 days. All validity criteria were met for validation of the study and criteria of the 10-day window. Thus, according to de Nadai (2009), the substance is readily biodegradable meeting the 10-day window.
