Description of key information

Additional information

Acute aquatic toxicity data for Daphnia, algae and STP microorganisms are available for dihydrogen hexahydroxyplatinate.


For acute toxicity to fish, data are read across from dihydrogen hexahydroxyplatinate, compound with 2-aminoethanol. Read across is considered to be appropriate as the platinum-containing component of the substance is identical to dihydrogen hexahydroxyplatinate, and in ecotoxicity test media dihydrogen hexahydroxyplatinate and 2-aminoethanol appear to separate rather than staying as a complex. Based on the available ecotoxicity data 2-aminoethanol is expected to be less toxic than platinum and therefore any toxicity is likely to be driven by the platinum component, although some additional toxicity due to 2-aminoethanol cannot be ruled out. As fish are not the most sensitive trophic level, the environmental classification of dihydrogen hexahydroxyplatinate is driven by data on the substance itself.
