Description of key information

The substance is not readily biodegradable with 30% degradation observed after 28 days (Bayer, 1999b) and not inherently biodegradable with 18% degradation observed after 28 days (Currenta, 2011a).

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The inherent degradability was determined on the basis of the oxygen consumption. As the substance contains nitrogen, the result has to be corrected for the oxygen consumed by nitrification rather than by degradation processes. Due to practicability, that oxygen demand was solely determined at termination of the test (day 28) causing a lower degradation as observed on day 27.
