Description of key information

Under the conditions of the test the EC50 > 100 mg/L. The substance is not considered to pose a hazard to Daphnia Magna

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
500 mg/L

Additional information

Testing of Reaktiv-Rot F-66 813 FW for acute toxicity in Daphnia magna (water flea) over a total of 48 hours yielded the following immobility values:

 

after 24 hours (mg/L)    after 48 hours (mg/L)

EC0      1000                          560

EC50       > 1000                > 1000

 

The concentrations tested were 0 / 560 / 1000 mg/L. Immobility was observed at 1000 mg/L.

In order to determine the substance concentration, water samples were taken at study end. All mean values were above 80 % of the nominal concentration.
