This approach has permitted the identification of processes related tothe origin, distribution and dispersion of sedimentary contaminants at small- and large-spatialscales. At small-spatial scales, point contaminant sources are predominant. The small-spatialscale variability of contaminant distribution is determined by the proximity to these pointsources and by changes in hydromorphological conditions. At large-spatial scales, diffusesources show a primary importance: these relate to the geological composition of the basinsand factors associated with urban development. On the shelf, the prevailing hydrodynamic andsediment transport processes favour the stable redistribution of heavy metals and pahs.The results obtained in this thesis provide a complete viewpoint of the processes and activitiesinvolved in the origin, distribution and dispersion of contaminants. Therefore, they can beconsidered as being an interesting source of scientific knowledge under current europeanmarine legislation (water framework directive and marine strategy framework directive) andcan be used for environmental management purposes.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Source, distribution and dispersion pattern characterization of
