Speciation and biogeochemical processes of trace elements in a Northeastern Atlantic Region: I. Levels and fluxes of trace elements in the Vigo Ria. II. Dissolved copper speciation in the freshwater discharges and estuarine mixing of a ria system. III. Impact of the Prestige oil spill on dissolved trace metal levels in Galician coastal and offshore waters

Abstract

[ES] La presente Tesis reporta un estudio detallado y extensor sobre los niveles y procesos relacionados con los metales traza en la Ría de Vigo y sus aguas costeras adyacentes. El trabajo ha cubierto muchas de las lagunas que existían sobre la investigación de metales traza en las rías gallegas, así como en sus aguas costeras y oceánicas colindantes. Con el fin de obtener resultados fiables, se han empleado técnicas limpias desde el muestreo hasta el análisis y la precisión de los métodos analíticos se ha chequeado mediante el uso de materiales de referencia certificados. Esta Tesis se compone de cuatro apartados principales: una descripción introductoria sobre la biogeoquímica de aguas costeras y estuáricas, una evaluación de los niveles y flujos de metales en los diferentes compartimentos de la Ría de Vigo, un estudio de la especiación orgánica del cobre y su comportamiento en los aportes continentales así como durante la mezcla estuárica y por último, una descripción del impacto del vertido de fuel procedente del petrolero Prestige sobre los niveles de metales traza en las fértiles aguas gallegas.

[EN] This Thesis reports a detailed and extensive study of trace metal levels and processes in the Vigo Ria and its adjacent coastal waters. It has filled a lot of the gaps on trace metal research in Galician Rias, coastal and adjacent waters. In order to produce reliable results, trace metal clean techniques have been employed and the accuracy of the analytical procedures has been checked through all the work with appropriate Certified Reference Materials. The thesis is comprised of four main parts: an Introductory description of estuarine and coastal biogeochemistry, a description of the concentrations and fluxes of metals within the Vigo Ria, an examination of copper speciation and behaviour in the continental inputs and during estuarine mixing in the ria and finally a description of the impact of the sinking of the oil tanker, Prestige, on trace metals in fertile coastal waters.
