Additional information

Some ecotoxicity data for diammonium hexachloroplatinate is available. Data are also read across from other platinum(IV) substances with a chloro ligand, hexachloroplatinic acid and platinum(IV) chloride, in order to fulfil REACH endpoints and to determine environmental classification.

 

Aquatic PNECs for platinum(IV) substances are derived by pooling all available data for platinum(IV) substances and deriving the PNEC using an assessment factor approach based on the ecotoxicity data for the most toxic platinum(IV) substance as worst case. Sediment and terrestrial PNECs are derived using equilibrium partitioning.

Conclusion on classification

Environmental classification is assessed based on the lowest acute and chronic values from ecotoxicity tests. Algae and fish toxicity values are read across from hexachloroplatinic acid. The lowest acute value is a 48-hour EC50 of 0.284 mg diammonium hexachloroplatinate L-1 (0.108 mg Pt L-1) based on the short-term toxicity study on aquatic invertebrates performed with the substance itself. The lowest chronic value is a 21-day NOEC value of 0.007 mg Pt L-1 for Daphnia, based on reproduction, read across from hexachloroplatinic acid. Converting the NOEC value to a concentration of diammonium hexachloroplatinate based on molecular weight gives a NOEC of 0.016 mg diammonium hexachloroplatinate L-1. As a complete chronic dataset (fish, Daphnia and algae) is not available, classification is assessed based on both the acute and chronic data and the worst case classification assigned to the substance. Based on the acute data, an environmental classification of Acute Category 1, Chronic Category 1 is assigned to this substance. As the lowest EC50 value is >0.1 ≤ 1 an acute M factor of 1 is assigned. A chronic M factor of 1 is also assigned, to match the acute M factor, as the classification has been determined based on acute data.
