Instrumental Neutron Activation Analysis (INAA) is employed for its important analytical properties. Fundamentally, INAA is a multielemental technique allowing the determination of about 30 elements with a good Limit of Detection. In this paper we applied this nuclear technique to the study of metal composition in fine and coarse fractions determining 25 elements. The filters collected in Rome were irradiated at the nuclear reactor Triga Mark II (ENEA- Casaccia Laboratories). The measurements of the ?-ray allow the quali- and quantitative analysis. The elements levels in fine and coarse fractions with the relative correlations have been determined: basically, the concentrations are very low. Furthermore, the enrichment factors of all elements will be reported in order to understand the natural or anthropogenic origins of the particulate matter.
