Since 25th January 1999 airborne particulate matter samples have been collected in three stations located at the North outskirts of Lisbon. The samples are analysed by two nuclear analytical techniques: Neutron Activation Analysis (INAA) and Particle Induced X-Ray Emission (PIXE). The multielemental characteristics of the two techniques used (INAA and PIXE) and its complementarity makes it possible to determine concentration for 37 elements. In this work mass concentrations obtained by gravimetry will be compared to the actual legislation and EPA limit values. Results for Lead, Chromium, Copper, Manganese, Nickel, Arsenic, Cadmium, Mercury, Potassium, Antimony, Vanadium and Zinc will be presented and compared in reference values.
