Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
48-hr EC50, immobilization, of FC-72 to Daphnia magna: >84.1 µg/L (water solubility value). FC-72 is not toxic at the limit of water solubility by read-across.
Key value for chemical safety assessment
Additional information
FC-72 is a member of the Perfluorinated Organic Chemicals, C5-C18 category. Recent, high-quality studies are available for toxicity to aquatic invertebrates of several category members including the next higher member of perfluoroalkanes group (i.e., perfluoroheptanes). In all cases, no toxicity was observed at the limit of solubility. The highest attainable measured concentrations ranged from 1.74 µg/L to 408 µg/L in these acute Daphnia toxicity studies. Loading rates were approximately 1000 mg/L except in the case of FC-770, which had a loading rate of 100 mg/L. This consistent lack of toxicity across members of the category is used for read-across to FC-72. Please see IUCLID section 13 for the category justification and a matrix of aquatic toxicity data for members of the Perfluorinated Organic Chemicals C5-C18 category.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
