The Development Plan of Taranto port (S. Italy) predicts the dredging of approx.20 Mt sediments, ≥10% of which are polluted. By appointment of Italian Environment Ministry, a detailed experimental investigation was carried out at laboratory and pilot-scale levels on the best available techniques to reclaim the polluted sediment so to reuse it in a technic and cost effective manner. A short pre-...

The management of dredged sediments is a priority issue in the Mediterranean sea where sediments are historically polluted. The aims of this study were to evaluate the toxicity of port sediment samples and the effect of three mineral additives (hematite, zerovalent iron (ZVI) and natural zeolite (NZ)) on sediment elutriate toxicity. Four sediments (A, B, C and D) were provided by port authoriti...

The environmental quality of Torre a Mare port (Italy) was assessed evaluating on one side, the chemical concentration of nine metals and metalloids within bottom sediments and on the other one, by exploring the impact of hydrodynamic conditions in contaminant's transport within the most polluted basins. The investigated port was selected as case study because it resulted much more polluted tha...

Algal species which are ubiquitous along the coastlines of many countries reflect the environmental conditions of the coastal seawater and may serve as useful biomonitors of anthropogenic pollution. Heavy metal concentrations of ten elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) of potential environmental concern were determined in seawater, sediments and twelve species of benthic marine ...

Marine ecosystems worldwide are threatened by aquatic pollution; however, there is a paucity in data from the Caribbean region. As such, five heavy metals (arsenic, cadmium, copper, zinc, mercury) were measured in tissues of the scleractinian corals Porites furcata and Agaricia tenuifolia and in adjacent sediments in the Bocas del Toro Archipelago, Panama. Samples were collected from five reef ...

The dispersal of fine sediments into receiving waters from dredging and disposal associated with major port developments, the modelling these, is often a focus environmental approval process for construction these works. An aspect that overlooked in assessment works generation sediment sourced directly materials used breakwater revetment construction. While offshore well documented, there littl...

This study discusses the results of ecological risk analysis sediments taken from Kilitbahir Port, one most active ports on shores Strait Çanakkale. ICP-MS analyzes collected samples revealed moderate enrichment in Mo, Cu and Zn relation to anthropogenic activities studied sediments. The compatibility geoaccumulation factor data explains that pollution is anthropogenic. No significant toxic was...

The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...
