Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Ammonia does not bioaccumulate and is a product of normal metabolism.
Key value for chemical safety assessment
Additional information
Ammonia is ubiquitous in the aquatic environment as a consequence of the breakdown of plant and animal material and due to animal excretory processes. The generation of ammonia by normal metabolism (protein catabolism) occurs in all animal species, and therefore all animal species have developed effective physiological mechanisms of detoxification (metabolism to other nitrogenous compounds) or excretion. In fresh water fish, ammonia is excreted across the branchial epithelium via passive diffusion.
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.
