Description of key information

Carboxylic acids, di-, C4-6 is considered to be readily biodegradable in soil.

Key value for chemical safety assessment

Additional information

For the mixture no data on biodegradation in soil are available. Adipic acid is applied for read-across approach.

Biodegradability of adipic acid in soil was assed in a test conducted according to a national standard method of the U. S. Food and Drug Administration (FDA). An 84 % conversion of adipic acid carbon content to carbon dioxide was found after 30 days aerobic incubation in a sandy loam (Sharabi,1993). 60 % degradation was reached in 1 to 6 d.

As it is shown that all constituents of the mixture are readily biodegradable, it is concluded that succinic acid and glutaric acid are also biodegradable in soil.
