Description of key information

In a limit test over 24 h Reactive Blue FC 15353 did not result in any immobility of Daphnia magna at a test substance concentration of 500 mg/L, which is hence equivalent to the EC0. Due to absence of effects an EC50 cannot be determined.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
500 mg/L

Additional information

A study was performed to assess the acute toxicity of test substance toDaphnia magnaunder static conditions. The study was conducted in accordance with German environmental agency draft Guideline ‘Bestimmung der Schwimmunfähigkeit beim Wasserfloh Daphnia magna, May 1984.

Daphnia were exposed to a limit test concentration of 500 mg/L test substance (nominal) dissolved in water.

Observations were made on the swimming ability and the immobilisation rate, respectively, after 24 and 48 h of exposure. The EC0 value at 24 h was500 mg/L.

Therefore, also the EC50 value of the test substance is established to be ≥ 500 mg/L.
