Description of key information
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.
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.
