Aerosol chemical composition data for PM2.5 and PM2.5–10 was acquired, in two sampling stations, at an industrialized area located in Sado Estuary. Two methods were used to have
an insight on the origin of the particles: the comparison between the measurements obtained in the two sampling stations and
the association between the wind direction and the element concentrations. Results showed that Ce, Fe, La, Sc, Sm, Na, Co
and Se were associated with non-local sources whereas As, K, Sb, Zn, Hg, Br, Cr, Hf and U had a local origin.
