Description of key information
As adipic acid is readily biodegradable, the study does not have to be conducted.
Key value for chemical safety assessment
Additional information
Adipic acid is shown to be biodegradable in surface waters and waste water treatment plants.
In a modified Zahn-Wellens-Test, using surface water from the river Main (Germany), 90% of adipic acid was degraded within 8 days (Zahn, 1980).
A waste water treatment simulation test was performed according to a method which is comparable to the OECD guideline 303 A ("Simulation Test - Aerobic Sewage Treatment. A: Activated Sludge Units). Sludge from a municipal sewage treatment plant was used in this test. After 1 day a DOC removal of 99% was achieved (Gerike, 1979).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
