摘要

this paper presents a brief review of the processes by which airborne heavy metals are transported from the main emission areas in Europe and become subject to deposition and absorption into terrestrial and aquatic ecosytems with subsequent transport and transformation within the biotic and abiotic media that comprise these ecosystems.Results from numerical simulation models capable of simulating long-range transport of heavy metal concentrations in air and precipitation anb the corresponding dry and wet deposition dluxes are reported.European wide inventories of anthropogenic heavy metal emissions burning in power plants,industrial and residential combustion,waste incineration and road traffic are briefly described.Emission reduction scenarios with respect to introduction of lead free gasoline are outlined.
