Port of Koper - Elemental concentrations in aerosols by PIXE

摘要

The elemental composition of PM10 aerosols in the vicinity of the open-air bulk terminal in the Port of Koper, Slovenia, was determined. Using a combination of short but intense and longer but relatively simple set-up of sampling points and sampling periods, we studied elemental concentrations ranging from S to Br and Pb due to the presence of the terminal and related activities. We observed a decrease in concentrations with respect to the distance from the source and a long-term correlation of different elemental concentrations detected during the non-stop 2-year sampling period. Two types of filters, Nuclepore and quartz fibre, were used for sampling as being most appropriate for different aims of the project. The filters were irradiated with 2 MeV protons at the PIXE beamline of the Microanalytical Centre at Jozef Stefan Institute (JSI). The elemental concentrations were obtained by analysing the recorded x-ray spectra with the GUPIX code. We found a strong correlation between iron ore transfer and Fe concentration in PM10.
