Description of key information

In a 48-h acute toxicity study, water fleas (Daphnia magna) were exposed to Sodium ferrocyanide under static conditions. The 48h-EC50 was >100 mg/L based on analytically confirmed nominal exposure concentrations. The study is considered to be reliable without restrictions.

Key value for chemical safety assessment

Additional information

In a 48-h acute toxicity study conducted according to OECD guideline 202, water fleas (Daphnia magna) were exposed to Sodium ferrocyanide under static conditions at the following nominal concentrations: 0 (blank-control), 0.10, 1.0, 10 and 100 mg/L. The test substance did not induce significant acute immobilisation of Daphnia magna at 100 mg/L after 48 hours of exposure. The 48h-EC50 was >100 mg/L based on analytically confirmed nominal exposure concentrations. The study is considered to be reliable without restrictions.

In addition, a supporting publication with potassium ferrocyanide was available, however no analytical support was available, and the test method was insufficiently described.
