Description of key information
96-hour LC50 (OECD203) to Danio rerio, >12 µg/L
Key value for chemical safety assessment
Additional information
In the key study, the toxicity of HFP kinetic dimer to zebra-fish, Danio rerio, was assessed in a 96-hour toxicity test conducted according to OECD 203, in accordance with Good Laboratory Practice (GLP) standards, and with analytical monitoring of test substance concentrations. Flasks at the highest loading rate intentionally contained undissolved test material which was allowed to settle before addition of fish. Test substance concentration was stable at the highest loading rate during the test, but decreased at all other concentrations. One mortality (of eight fish) was observed at the highest loading rate, and half of fish had sublethal, visual effects at this loading rate. The LC50 based on geometric mean concentration was >12 µg/L, or >5 mg/L based on nominal concentration. This study is reliable without restrictions. Two additional studies cannot be considered reliable.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
