Heavy Metal Species, Mobility and Availability in Soils

摘要: The ecological effects of heavy metals in soils are closely related to their content and species distribution the solid liquid phases soils. Methods for determination metal both described critically evaluated. In connection with possible binding mechanisms concept specific nonspecific adsorption is discussed. Recent results indicate that on soil particles not only restricted formation surface complexes but can also take place structure minerals. Diffusion processes into minerals goethite. order assess mobility availability soils, concentration solution or comparable aqueous equilibrium solutions samples, transfer from pools phase, vice versa, have be assessed. amount plant-available associated problems
