MULTIELEMENTAL CHARACTERIZATION OF AEROSOL AT TERRA-NOVA BAY - PRELIMINARY-RESULTS ON THE FINE COMPONENT DURING THE 1990-91 AUSTRAL SUMMER

Aerosol sampling has been performed at Campo Icaro, in the vicinity of the Italian Base at Terra Nova Bay, in the period between november 1990 and february 1991. The duration of the sampling intervals was approximately 12 hrs and a special aerosol sampler was used, with separation of the coarse and fine (empty set(aer) less-than-or-equal-to 2.3-mu-m) components. We present aims and methods of the experiment as well as the results of a PIXE analysis of 89 samples of the fine component, collected on Nuclepore filters. Mean values and standard deviations of volume concentrations (ng m-3) for the following elements : Si, S, Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, are given.
