For coarse particles, high concentrations of Al, Fe, K and Ca suggested that re-suspended soil dust was the main source of aerosol trace elements, subsequently confirmed by XRD analysis. High levels of K, Zn, As, Cd and Pb were found in fine particles, confirming the contribution of biomass burning and vehicle emissions, whereas Na, Al, K, Fe and Zn were the representative elements in ultrafine particles, influenced by a diversity of sources.porAcesso AbertoAtmosferaMaterial Particulado Atmosférico (MPA)Elementos traçosGeoquímica ambientalAraraquara (SP)Artigo de Periódico
