The different fractions of organic micropollutants metals (dissolved, total and adsorbed) are simulated on different model grids for the North Sea. The model grid resolution varies from 1x1 km (near-shore) to 16x16 km (off-shore). The model input consists of emissions from the major rivers entering the North Sea, boundary conditions, emissions from dumping sites, emissions from off-shore and shipping activities and atmospheric deposition. The model process formulations are based on equilibrium adsorption/desorption to particulate matter, sedimentation and erosion and interaction with the atmosphere. Residual as well as inter-tidal currents are simulated with a hydrodynamic model. The model is calibrated against the yearly averaged in-situ measurements of Rijkswaterstaat (DONAR database).
