River Sediments as a Trap for Metal Pollutants

The efficiency of river sediments to scavenge heavy metals released from industrial waste (slag) was tested in this work. Sediments and water chosen were sampled from the River De&ucirc ; le canal (northern France). The concentrations of Pb, Cd, Zn and Cu measured in river sediments were 10 to few hundreds times higher than the background values. Slag particles were composed mostly of Al, Fe, Ca, Mn, Zn, Pb, Cd, Cu and Cr and in contact with river water they released high concentrations of Pb, Cu and Cr. When sediments were added to the river water – slag mixture, the remobilization of those metals was not so expressed. As it were, in spite of the high metal pollution level, sediments have shown the ability to adsorb metals released from slag under the conditions provided.
