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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
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 Pt 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).
Biodegradation has not been assessed for the substance as a whole as this endpoint is not relevant for inorganics. However, biodegradation potential of the organic component of the substance has been assessed (Desmares-Koopmans, 2014). Desmares-Koopmans (2014) is a GLP-compliant study following OECD guideline 301B. It is reliable without restrictions and can be used as a key study for this endpoint. Tetraethylammoniumhydroxide (TEAH) 35% in water was designated as not readily biodegradable.
A hydrolysis study has not been conducted for this substance as it is not considered to be scientifically necessary.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
