Description of key information
Fumaric acid is readily biodegradable.
Additional information
The ready biodegradability of fumaric acid was determined using the OECD 301B guideline in a GLP study reported in 2010. Using a non-adapted sludge from a domestic source the percentage of biodegradation observed comprised 60.1 % after 11 days (i.e. within the 10 -d window) and 67.5% after 28 days. The reference substance (sodium benzoate) incubated under the same conditions showed a percentage biodegradation of 60.1 % after 11 days. Incubation of the test substance and the reference substance demonstrated that the test substance did not significantly inhibit the microbial activity of the activated sludge.
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.
