Description of key information
The toxicity of iodine pentafluoride to fish is derived from ecotoxicity data of its degradation products iodide, iodate and fluoride. 96-h LC50 values for iodide, iodate and fluoride are 860, 220 and 51 mg/L, respectively in rainbow trout.
Key value for chemical safety assessment
Additional information
No aquatic toxicity studies with iodine pentafluoride are available or can be performed as in contact with water iodine pentafluoride reacts instantly and violently under formation of hydrogen fluoride and iodate. Hydrogen fluoride will further react to fluoride and iodate in water forms an equilibrium with iodide. Therefore available data from studies with fluoride, iodate and iodide are given as indication of the aquatic toxicity of iodine pentafluoride.
In the Laverock study, rainbow trout (Oncorhynchus mykiss; 10/concentration) were exposed to a control and six concentrations of iodate and iodide under static conditions for 96 hours. The test concentrations were determined as 0, 1, 3, 10, 30, 60 and 100% of lethal concentrations as determined in a preliminary test. Test concentrations were analysed as total iodine in the test system. For iodate the lethal concentration was determined at 1.0 g iodine/L, for iodide this concentration was 10 g iodine/L. Mean ratios of final total iodine concentrations to initial total iodine concentrations were 1.06 and 0.99 for iodate and iodide, respectively. The 96-h LC50 values for iodate and iodide were 220 and 860 mg/L, respectively.
In the EU Risk Assessment Report for hydrogen fluoride several fish studies are reported. All reported tests were performed with sodium fluoride and the results corrected for the fluoride ion. From the different studies reviewed in this report, the lowest effect-value was observed in rainbow trout with a 96 -h LC50 of 51 mg fluoride/L. Although methodological data are incomplete, the data have been reviewed by the EU and are therefore considered to be suitably reliable for environmental risk assessment.
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).
