| Abstract: | The contribution of the atmosphere to the input of heavy metals to marine environments of Northern Europe is determined by applying an EMEP-type Lagrangian trajectory model. The results show that the model is capable of simulating long-range transport of heavy metals from European anthropogenic sources to the North Sea and the Baltic Sea including emission reduction scenarios for lead. Model calculations for lead indicate maximum annual inputs from the atmosphere of more than 2,400 tonnes for the North Sea and 1,300 tonnes for the baltic sea. It was calculated that in the 1985–1990 time period, mainly as a consequence of use of unleaded gasoline, the trend show a pronounced decrease of the deposition fluxes of lead from the atmosphere. |
