In this study we have investigated air-sea exchanges in the Belgian coastal area located in the Southern Bight of the North Sea. Since 1980 the tropospheric aerosol contents for the trace elements Cd, Cu, Mn, Pb, Zn and for the reference elements Al , Fe, Na have been monitored on an intermittent basis from a maritime sampling platform (Light-Vessel West-Hinder; position: 51°23.5'N- 2°21.5'E, fig. 1). During 1981 sampling campaigns at sea were paralleled by sampling campaigns on land, in the coastal area (natural reserve De Blankaert, located at 20 Km inland), in order to allow for a better evaluation of the specific source or sink role of the sea. No major source of pollution exists between the maritime and the continental sampling sites. During these simultaneous land-sea campaigns dry deposition and rainwater were sampled, besides aerosols. Furthermore, the sea surface microlayer and the water column in the vicinity of the Light-Vessel were investigated for possible enrichments and in order to allow an estimation of the resuspension flux.
