Abstract


PM2.5 and PM10 samples were collected in two monitoring stations located in Duque de Caxias (Rio de Janeiro), near Campos Elíseos petrochemical complex. Concentrations of metals in the samples were determined by ICP-OES (Inductively coupled plasma optical emission spectroscopy). Ca, Mg, Fe and Al were the most abundant elements in PM10 and were also present in PM2.5 in lower amounts. Zn, Cu, Cd and Pb were identified in all samples. Calculated enrichment factors (EF) show that these elements are probably of anthropogenic origin and are due to fuel and oil composition. EF for Pb and Cd are very high in comparison to typical values for areas where vehicular emissions are the only source, suggesting for industrial contribution. Co was under its detection limit in all samples. Mn, Cr and Ni concentrations were lower but in most of the samples were over their detection limits.
