Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on the chemical structure and properties an adsorption to soil particles is not expected. Furthermore, sodium nitrite dissociate in the environment immediately into sodium and nitrite ions. Nitrite will be rapidly transformed into nitrate by microbiological activity; thus, adsorption of sodium nitrite is unlikely. Therefore, based on the very high water solubility and the very low vapour pressure sodium nitrite will be mainly distributed in water.
