摘要

Aerosol particles were collected in different environments in Poland-in Legnica, a middle size town situated close to big copper works and in a rural site in the suburbs of Krakow, the city three times bigger than Legnica. Bulk analysis of particulate matter collected on quartz-fibre filters was performed using spark source mass spectrometry (SSMS). Analysis of airborne particles from urban and rural environments revealed differences in partial concentration of 20 selected elements. In urban aerosol collected in Legnica we found more: Pb, Cr-20 times than in the rural environment, As, Sr-10 times, Co-7 times, Cl-5 times, V, Y-3 times, Ti, Mn, Cu, Se-2 times and Fe, Ni, Zn, Br, Zr, Mo almost 2 times more than in the rural environment.
