Acute toxic to aquatic invertebrates.

Key value for chemical safety assessment

Additional information

As with fish, there are several studies with a wide variation in toxicity between species reported in an OECD SIDS dossier. Sodium nitrite is toxic to freshwater invertebrates such as Cherax quadricarinatus (LC50 (96h) = 4.93 mg NaNO2/L; Rouse et al, 1995), representing the most sensitive species; whereas marine species, such as Metapenaeus ensis (LC50 (120h) = 34.8 mg NaNO2/L; Chen & Nan 1991) are less sensitive.
