Description of key information

Acetic acid has been determined to be readily biodegradable on the basis of a weight of evidence approach.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

There are no robust studies for biodegradation available for acetic acid. The DAR uses a number of non-standard studies to support a determination that acetic acid is readily biodegradable. In addition, they comment that the use of the salt form sodium acetate is used as a reference substance in OECD screening tests for ready biodegradability.

A QSAR has also been generated to support the determination that acetic acid is readily biodegradable.
