| Abstract |
|
Studies carried out to evaluate sediment contamination in the Lagoon of Venice emphasized important problems of pollution in the central Lagoon1-3 However very few is known about the contaminants mobility, the exchanges between water and sediments can be responsible for secondary pollution deriving from re-mobilization of pollutants introduced in the past time. Processes responsible for these fluxes are the upward flow of pore water caused by diffusion and bioturbation. In coastal areas, characterized by low depth and organic rich waters, changes of oxygen concentration in the waters can produce variations in trace components cycling, that can generate both upward and downward fluxes4,5. These events are common in transition environments such as that in the Lagoon of Venice. The aim of this research program is to investigate the mobility of trace elements using benthic chambers at two sites characterized by high metal concentration. Here we report preliminary results obtained to evaluate the mobility of Pb, Cd and Cu and Fe; samples were analysed for nutrients, metals in dissolved and particulate phases; thiol compounds as candidates for specific complexing ligands were also determined in the dissolved phase.
