Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

With high probability acute not harmful to aquatic invertebrates
Key value for chemical safety assessment
Additional information
For risk assessment of ammonium bicarbonate the total topic of ammonia toxicity was regarded. Species mean acute values (SMAV), as given by U.S. EPA (1999) were considered as relevant endpoints. According to the U.S. EPA (1999) approach, the species mean acute values (SMAV) expressed in terms of total ammonia nitrogen at pH 8 range from 25.78 to 1466.35 mg N/L for aquatic invertebrates. The lowest SMAV at pH 8 was obtained in Ceriodaphnia acanthina: 25.78 mg N/L = 145.6 mg/L Ammonium hydrogencarbonate. The adjusted species mean total ammonium nitrogen acute value for Daphnia magna as presented by U.S. EPA (1999) is 35.76 mg N/L at pH 8 and corresponds to 202 mg/L for ammonium hydrogencarbonate.
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.
