Description of key information
Following cold water extract (5 days) and filtration (0.2 µm), analysis was conducted using ICP-MS, The elements detected were Ba, Ca, Cu, Ir, K, Mg, Na, Pd, S and Sr.
Key value for chemical safety assessment
Additional information
Residues, cementation and reduction, precious metal refining was analysed using ICP-MS following cold water extraction and filtration (Aqura 2014). The GLP status of this study is not known, but it follows a standard method and is considered to be suitable for use as a key study for this endpoint.
