Description of key information
The Kd values of 16185.05, 1878.31 and 595.32 were determined for Soil 2.3, 2.4 and 6S, respectively, after 48 h.The Koc values of 2415679.1, 94864.0 and 34411.7 were determined for Soil 2.3, 2.4 and 6S, respectively, after 48 h.
Key value for chemical safety assessment
Additional information
A study with tetrachloro auric acid, was conducted according to OECD 106 guideline to determine the Adsorption – Desorption.
A limited partitioning study with three soils was performed to determine the Kd values (Klawonn 2016). The approach was considered adequate for the information requirements and a read across of the data to gold has been considered appropriate.The Kd values of 16185.05, 1878.31 and 595.32 were determined for Soil 2.3, 2.4 and 6S, respectively, after 48 h.The Koc values of 2415679.1, 94864.0 and 34411.7 were determined for Soil 2.3, 2.4 and 6S, respectively, after 48 h.
