Endpoint summary

Description of key information
This endpoint has been waived as it is scientifically unjustified for ammonia. No bioaccumulation is expected for AlN and its hydrolysis products aluminium ions and ammonia.
In general, metals do not biomagnify unless they are present as, or having the potential to be present, in an organic form (e.g. methylmercury). Organometals tend to be lipid-soluble, are not metabolised, and are efficiently assimilated upon dietary exposure. The available evidence shows the absence of aluminium biomagnification across trophic levels both in the aquatic and terrestrial food chains. The existing information suggests not only that aluminium does not biomagnify, but rather that it tends to exhibit biodilution at higher trophic levels in the food chain.
Ammonia is part of the global nitrogen cycle and is not expected to biomagnify in the environment, due to its rapid biodegradation and hydrophilicity.
Additional information
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.
