Abstract
    In an effort to assess the atmospheric input of heavy metals to the Southern Bight of the North Sea, aircraft-based aerosol samplings in the lower troposphere were performed between September 1988 and October 1989. Total atmospheric particulate and size-differentiated concentrations of Cd, Cu, Pb and Zn were determined as a function of altitude, wind direction, air-mass history and season. The obtained data are compared with results of ship-based measurements carried out previously and with literature values of Cu, Pb and Zn, for the marine troposphere of the southern North Sea. The results point out the high variability of the concentrations with the meteorological conditions, as well as with time and location. The experimentally found particle size distributions are bimodal with a significant difference in fractions of small and large particles. These large aerosol particles have a direct and essential impact of the air-to-sea transfer of anthropogenic trace metals, in spite of their numerical abundance and relatively low heavy metal content.
