Description of key information

The effective concentration (EC50) value of diiodohydroxyquinoline in aquatic invertebrate (Daphnia Magna) in a 48 hr study on intoxication effect was estimated to be 12.50081mg/L. In another supporting study, the L50 value of diiodohydroxyquinoline to Daphnia Magna) in a 48 hr study on the basis of mortality effect was estimated to be 10.37779mg/L. However, the BCF value of diiodohydroxyquinoline reported was not >= 500 as well as the substance was found to be rapidly degradable. Thus considering the CLP Criteria for aquatic classification of the substance , it is concluded that diiodohydroxyquinoline could not exhibit short term toxicity to aquatic invertebrate Daphnia
