“…Indeed, marine sediments are normally utilized as indicators to identify environmental impacts [1][2][3]. Once the potential risks of contaminated sediments have been assessed by tiered ecological risk assessment frameworks, it would be necessary remediation actions including dredging [4].…”

The effect of the heating temperature on the properties of sintered ceramic bodies from three different contaminated marine sediments was investigated. The sintering behaviour was evaluated by means of the variation of shrinkage degree, bulk density, water absorption, open and closed porosity, while the phases transformation were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results have shown that the sintering process follows a viscous liquid phase mechanism due to the formation of a glassy phase. The optimum sintering temperature is 1125ºC for Astilleros and Cuchia sediments and 1150ºC for Raos sample. Above this temperature, a significant overfiring with an increase of closed porosity was observed. Water absorption values and mechanical properties as bending and compressive strengths of sintered bodies show that the investigated marine sediments are suitable to be used as secondary raw materials in ceramic tiles and bricks production.

“…The study of occurrence, fate and distribution of trace metals in estuarine environments has deserved to receive major attention, mainly because of their persistent toxic effects, as well as their ability to be accumulated within compartments of these environments (Salomons, 1995;1996). Thus, knowledge of both the physical and physicochemical processes controlling the behavior of heavy metals is a basic requirement for the understanding of their potential toxicity in the environment.…”

“…Due to the complexity of the soil or sediment system and the variability of numerous influencing factors, long-term prognosis on the mobilization of metals from soils or sediments is highly uncertain (Salomons, 1995). Because of the long term involved, verification of model predictions from field observations is not possible.…”

Leaching of heavy metals from land disposed dredged sediment spoils is a potential environmental hazard. The leaching behavior of Cd, Cu, Pb and Zn in surface soils sampled from abandoned dredged sediment disposal sites was assessed. Using simple mass-balance calculations, the significance of the leaching test results with respect to metal migration into underlying clean soil was appraised. The potential leachability, defined as the amounts released at constant pH 4, decreased in the order (% of total contents): Zn (58 %) ≈ Cd (49 %) > Cu (5 %) ≈ Pb (2 %). The kinetics of metal release were determined in a cascade shaking test using demineralized water acidified to pH 4 (HNO 3 ). Metal concentrations in the leachates were low and metal migration was, assuming uniform convective flow, predicted to be of no environmental concern. It is emphasized that any long term prediction of metal migration is uncertain.
