Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Bioaccumulation is not considered a relevant endpoint for monochloramine as it is an inorganic substance, which is soluble in water, used in an aqueous solution at low concentrations in water treatment and thus highly diluted when entering the aquatic environment. Furthermore hydrolysis (T1/2= 10h) and/or degradation (T1/2dependent on factors such as pH, T, light conditions) of monochloramine in the aquatic environment, will limit the amount of bioavailable monochloramine.
Moreover, the ECHA Guidance on information requirements and chemical safety assessment - Chapter R.7c: Endpoint specific guidance (2008, p. 64 -65) states that the BCF value for inorganic substances will be influenced by water chemistry (e.g. pH, hardness, temperature, redox conditions) and generally only dissolved ions will be potentially available for direct uptake.
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.
