Abstract: The bioavailability and mobility of potentially toxic trace metals largely determine the environmental impact of metal-contaminated soils and aquatic systems. The first aim of the present work was the assessment of metals bioavailability in both soils and river waters through the comparison of the most widespread techniques used to infer metals mobility in the environment and its uptake by biota. Concerning soils, traditional techniques as leaching and extraction tests has been used in parallel to a relatively recently developed technique known as Diffusive gradients in thin films technique (DGT) capable of in situ measurement of labile metal species in natural waters, sediments and in soils. Selected leaching and extraction tests and DGT were applied to a range of metals contaminated Italian soils and their limits and field applicability were discussed. In this work, leaching tests provided an estimation of the maximum availability of metals for release from the soil matrix ...
