Objective RV COTES DE LA MANCHE had engine problems and did not leave quay in Bayonne. Therefore, the operations were done from a zodiac dinghy. The objectives were to: Determine the amounts of metallic pollutants (Hg, Cu, Zn, Sn, Cd, Pb, As, Sb,) in the different aquatic compartments of the Adour and Nervion estuaries. Characterize the exchanges of metals between the different compartments (dissolved/particulate), between the different chemical forms (organic, inorganic, free, methylated)of these metals, and the related toxicological risks, through the salinity gradient vertical profiles in the water column (interface where marine and fresh water mix). This was done through systematically studying the distribution of metallic pollutants in the Adour and Nervion estuaries with respect to the salinity (gradient), the geographical position (e.g., for sediments) and of seasonal parameters (flood/slack). These studies should enable the available fractions of these metals (free and labile forms), which are known as being the most toxic to living organisms to be assessed and the exchanges between the different fractions to be modelled. Comparing the two Adour and Nervion systems by a statistical data study should enable the levels and sources of potential pollution and their environmental impact to be characterized. This falls under the Aquitaine/Euskadi/Navarre joint cooperational fund (Aquitaine regional council).
