The management of dredged sediments is problematic in some French regions due to their significant contamination by organic and/or mineral pollutants. In this study, dredged sediment from a seaport was treated by composting and chemical stabilization. Sediment contamination (organic and mineral pollutants) was characterized, and samples...

This work investigates arsenic mobility, bioavailability and toxicity in marine port sediments using chemical sequential extraction and laboratory toxicity tests. Sediment samples were collected from two different Mediterranean ports, one highly polluted with arsenic and other inorganic and organic pollutants (Estaque port (EST)), and the other...

The management of polluted sediments is problematic because to date no economically suitable process allows the complete and durable stabilization of pollutants. Some marine sediment contains arsenic at concentrations far higher than the limit that imposes a specific treatment to reduce their toxicity. The aim of ASEDMAR project...
Arsenic speciation was determined in marina sediments of the French Mediterranean coast. The sediment from L'Estaque marina was highly impacted by both metallurgical activities and by the commercial port of Marseille, in contrast to the sediment from St Mandrier marina that was less polluted. In the solid phases, As(III) was the dominant...
Harbour and marina sediments represent particular environments, with high concentrations in organic carbon and pollutants. Over 50 million m3 of marine sediments are dredged every year in French maritime and commercial ports, to maintain the water depth suitable for navigation, and the most part of them is discharged in deeper sea zones. The...

This study investigated the influence of uranium on the indigenous bacterial community structure in natural soils with high uranium content. Radioactive soil samples exhibiting 0.26%-25.5% U in mass were analyzed and compared with nearby control soils containing trace uranium. EXAFS and XRD analyses of soils revealed the presence of U(VI) and...
