Abstract
Characterizing the factors which affect the mobility, bioavailability, leaching and toxicity of metals and metalloids in soil environments is of paramount importance. Special attention is devoted to the influence of biomolecules, mainly roots exudates, as well as pH, nature of the sorbents, redox reactions on the transformation mechanisms of trace elements in cationic and anionic forms in soils. Time of reaction and the surface coverage have a great influence on the sorption/desorption processes of trace elements in the presence of organic ligands. Leaching and extraction tests are widely used for assessing trace element phytoavailability.
