Abstract
Neutron activation analysis (NAA), X-ray fluorescence (XRF), proton induced X-ray emission (PIXE), atomic absorption spectrometry (AAS) and ion chromatography (IC) were used for the chemical characterization of airborne particulate matter in Santiago, Chile. The PM10 mass and elemental concentration were higher in the winter than in the summer collection period. Analytical quality assessment for NAA, XRF, PIXE, AAS and IC was performed on some samples. Correlations were found between the elements Pb−Br, Si−Ca−Fe, As−Cu−S and also between the fine mass and black carbon concentrations, which could be associated with some relevant sources.
