Description of key information

For dipotassium hexachloroplatinate, ecotoxicity data are read across from another platinum(IV) substance that also contains a chloro ligand, hexachloroplatinic acid. The 96-hour LC50 was determined to be 25.78 mg Pt L-1.

Key value for chemical safety assessment

Additional information

An acute Oncorhyncus mykiss study is available for hexachloroplatinic acid following OECD guideline 203 and EU Method C.1 (Pawlowski and Wydra 2005). A static test procedure was followed. Five test concentrations were used and these were analysed using Graphite furnace-AAS method. As measured concentrations were above 100 % of the nominal values throughout the study, with a mean of 107 % of nominal, results were based on nominal concentrations. No protocol deviations were recorded. The experiment was considered to be valid because no fish died in the control and oxygen saturation was always greater than 60 %. The 96-hour LC50 was determined to be 76.55 mg test item L-1 (25.78 mg Pt L-1). The 96-hour NOEC was determined to be 21 mg test item L-1 (7.07 mg Pt L-1).
