摘要：
Aerosol sampling was 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 fraction from the fine (phi(aer) < 2.3 mum) fraction. We will present the aims and methods of the experiment as well as the results of the PIXE analysis of 51 samples of the coarse fraction, collected on Nuclepore filters. Mean values and standard deviations of volume concentrations (ng/m3) are given for the following elements: Al, Si, S, Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br.
