Description of key information

In the test period of 27 days diethyl carbonate pure was degraded to 75 % . The test substance was not found to be toxic to bacteria at the test concentration.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

After six days 35 % were degraded, after 16 days 70 % were degraded (10 -day window, Guidance on information requirements and chemical safety assessment, Chapter R.7b: Endpoint specific guidance, R.7.9.4 Evaluation of available information on degradation/ biodegradation, p. 171).
