| Abstract | Several samples collected from two main rivers (Souani and Mghogha) and the largest pipeline of Tangier's city that pours into Tangiers bay (Mediterranean Moroccan margin), were analysed with the objective of evaluating the chemical and/or organic contamination degree of superficial sediments present along these continental emissaries. The sedimentary dynamics of these rivers show coarsening upstream evolution, influenced by the urban and industrial liquid and solid discharges (infilling basin side with building materials such a bricks, cement, glass, etc.). Organic matter is present with high concentration, showing a positive correlation with the sediment fine fraction. Total Nitrogen displays a parallel evolution with the organic matter, with especially high concentrations near the urban sewage. The six heavy metals analyzed in the superficial sediments, show variable but relatively high concentrations, mainly in the fine fraction, with Zn < Cr < Pb < Ni < Cu < Cd. The correlative study of these metallic elements prove their double anthropogenic and natural origin. |
