    Determination of trace elements in aerosol samples by instrumental neutron activation analysis
    1990 - PAIVA, R.P.; MUNITA, C.J.S.; CUNHA, I.I.L.; ROMANO, J.; ALONSO, C.D.
    Two nuclear techniques, Energy-Dispersive X-Ray Fluorescence Analysis (EDXRF) and Instrumental Neutron Activation Analysis (INAA), were used to analyze aerosol samples collected in the city of Sao Paulo, Brazil. Na, CI, Mn, V, A1, Sm, Mo, W, La, As, Br, Sb, K, Ba, Se, Th, Cr, Rb, Ca, Fe, Ce, and Sc were determined by INAA, and A1, Si, P, S, C1, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Hg, and Pb were determined by EDXRF. A preliminary identification of the main source of the atmospheric aerosol was performed based on enrichment factor and correlation coefficient calculations.
