Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The log Kd for water is 3.27 (stdev 0.34) and the average Kd is 1862. The log Kd for soil is 1.57 (stdev 0.46) and the average Kd is 37.2.

Additional information

Two high quality studies have determined the partitioning of platinum between river water and suspended particulate matter. Both studies showed relatively consistent results for experiments performed in freshwaters, and similar partitioning was also observed in both estuarine and marine water in the key study (Turner et al., 2006; Cobelo-Garcia et al., 2008). A high quality study of the partitioning of platinum to two soils and one sediment provides information relevant to the soil compartment (Sako et al., 2009).

Hydrolysis and biodegradation potential have not been assessed for this substance as these endpoints are not relevant for inorganics.
