title = "Derivation of partition relationships to calculate Cd, Cu, Ni, Pb, Zn solubility and activity in soil solutions",
abstract = "The distribution of heavy metals (Cd, Cu, Ni, Pb and Zn) between soil and soil solution was measured in more than 1400 soil - solution samples. These samples reflect the variability that occurs within the Netherlands and covers all major soil types. The distribution of metals between solid phase (adsorbed) and the soil solution was described using an extended Freundlich equation taking into account the impact of organic matter, clay, pH and Dissolved Organic Carbon. Apart from this, the impact of Fe and Al oxides was tested. The free ionic activities were also calculated from the data and partition relationships were derived for both total dissolved metal contenrations and free metal ion activities. The results show that an extended Freundlich equation is able to represent the wide range of total dissolved concentrations and free ion activities that are encountered in the database. For the metals Pb and Cu, the uncertainty in the predictions is, however, rather high. Further model improvement is required for these metals.",
