Metallic transfer at water-sediment interface in an urban river watercourse
In industrial areas, watercourses constitute potential hazards due to the underlying heavily contaminated sediments. Physical disturbances at the water-sediment interface, induced by natural or anthropogenic events, can result in resuspension of contaminated sediments and remobilisation of pollutants into the water column. The aim of this study is to assess the impact of sediment dynamic on metallic transfer at water-sediment interface in a canalised river characterised by polluted sediment: the Scarpe River, North of France. The technique of DET (Diffusive Equilibrium in Thin Films) was applied to obtain high-resolution vertical profiles of trace metals in sediment porewaters. The sequential extraction procedure was conducted on superficial sediments in order to assess the potential metal availability.
