| Short description: |
Although mesoscale models of atmospheric transport of toxic substances are in use for years, large-scale models of overland transport are still under development. The overland transport is a result of complex interactions and its practical and theoretical investigation is therefore a complicated task: Toxic substances which contaminate the land via atmospheric deposition are subject to numerous processes until they reach the river systems. According to their physico-chemical properties they are adsorbed to the soil, leach to subsurface water and groundwater or are transported further over land into the freshwater systems via runoff. Satisfactory estimations of atmospheric input into European terrestrial and aquatic systems exist for numerous substances but the contribution of overland transport to freshwater contamination after deposition is more or less uncertain. Knowledge about the quantity of toxic substances reaching the European aquatic or marine systems or about the retention during the transport throughout the river catchments is still short. Sediments of both the aquatic and marine systems show constant high concentrations in Europe. To get a first overview of the historic and present contamination of European soils and waters originating from atmospheric deposition appropriate forecast and reconstruction techniques are needed.
