Popis:	In the present work we have analyzed aerosols deposits on filters from ten Romanian towns: Pitesti, Giurgiu, Resita, Ramnicu-Valcea, Baia-Mare, Craiova, Timisoara, Calarasi, Braila and Arad with different kinds and levels of industrial development by PIXE method using Yttrium like internal standard because it is a very rare element in the environmental items. We have identified 15 elements: S, K, Ca, Cr, Ti, V, Mn, Fe, Co, Ni, Cu, Zn, As, Hg and Pb. The measured elemental concentrations are given with respect to the concentration of the Ca for all analyzed samples. The obtained results can put in evidence a high ratio of Ti/Ca, Cr/Ca, Fe/Ca, Co/Ca, Zn/Ca, As/Ca, Pb/Ca in Craiova, a high ratio of Mn/Ca in Calarasi and a high ratio of Hg/Ca in Braila. Certainly the level of pollution of a region can not determine by a single filter and is need of a good statistic to draw conclusions.
