Additional information

The 48-h acute toxicity of Reactive Red FC73270 to Daphnia magna STRAUS, parthenogenetic females, was studied under static conditions.  Daphnids were exposed to 25, 50 and 100 mg/L of the test substance for 48 h. The 48-hr EC0was 27 mg/L (aithmetic meand measured concentration). EC50was > 27.0 mg/L and < 97.2mg/L. All validity criteria met.
