Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In the environment sodium nitrite will dissociate into sodium and nitrite ions. Nitrite ions are a component of the nitrogen cycle. In the environment, bacteria of the genus Nitrobacter oxidise nitrites to nitrates. Nitrates are reduced to nitrogen by anaerobic bacteria present in soil and sediment. In addition, since direct exposure of the soil compartment is unlikely and binding to solid phase (e.g. clay) of sodium nitrite is negligible no test on terrestrial organisms are performed. Therefore, risk assessment will be based on EPM.
