PurposeMetal mobility in contaminated marine sediments is largely controlled by low-soluble sulfides. In dredged sediments exposed to air and water, geochemical and microbial-mediated processes may enhance the weathering and leaching of hazardous contaminants, especially trace metals. The objective of the present study was to thoroughly characterize and assess the biogeochemical reactivity of marine-dredged sediments.
