Performance of a nuclear microprobe to study giant marine aerosol particles
The importance of heavy metal contamination of large water bodies has been under investigation since the late 1970s. To determine atmospheric parameters which describe the heavy metal flux into the North Sea, physical aerosol size distributions and also elemental size distributions were measured and deposition velocities calculated. Several analytical methods were used to determine the atmospheric metal concentrations based on size-segregated bulk samples of aerosols. To distinguish between different particle compositions in the same size range, individual particle analysis was performed with laser microprobe mass analysis (LAMMA). The aim of the work is to improve determination of elemental aerosol size distributions above the North Sea, which in turn will contribute to a reliable estimation of heavy metal input into the sea.
