Sources of trace elements in fine and coarse particulate matter in a sub-urban and industrial area of the Western European Coast
چکیده انگلیسی

In the present study, Positive Matrix Factorization (PMF) is used as a tool for the source apportionment of trace elements in atmospheric particles. Samples were collected at sub-urban and industrialized sites located in the northern region of the Great Lisbon. A set of 16 elements determined by Instrumental Neutron Activation Analysis (INAA) was considered for PMF analysis. Results show the contribution of soil, sea, industry, vehicular exhaust, vehicular wear and road paved dust. Results state the importance of different emission sources associated to roadways, but in most cases the model could not distinguish between different industrial sources.
