Additional information
Di(tetraethylammonium)hexahydroxoplatinate(IV) is a member of the category of "Platinum(IV) substances".
As such, the data requirements for this substance are covered by relevant and reliable experimental test data generated for all members of this category via a read-across approach.
A read-across justification report and PNEC derivation report are attached in IUCLID Annex 13.
Conclusion on classification
The environmental classification of di(tetraethylammonium)hexahydroxoplatinate(IV) is assessed based on the lowest acute and chronic values from ecotoxicity tests performed with the substance itself. A full base set of ecotoxicity data are available for di(tetraethylammonium)hexahydroxoplatinate(IV). The lowest acute value is a 72-hour EC50 of 0.73 mg test item L-1 (0.08 mg Pt L-1) and the lowest chronic value is a 72-hour EC10 of 0.46 mg test item L-1 (0.05 mg Pt L-1) for aquatic algae and cyanobacteria (yield). For di(tetraethylammonium)hexahydroxoplatinate(IV), the only chronic data available is an algal EC10, therefore classification is assessed based on both the acute and chronic data and the worst case classification assigned. Based on these results, an environmental classification of Acute Category 1, Chronic Category 2 is assigned to di(tetraethylammonium)hexahydroxoplatinate(IV).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
