INVESTIGATION OF HARMATTAN PARTICULATES FROM KANO AND IFE, NIGERIA

The size distribution, elemental composition, shape and surface textur e of harmattan particulates of distinctly located points have been exa mined. The characterized particle size ranges are 0.7-16.4 mu m and 0. 6-19.7 mu m for Kano and Ife respectively, A total of 12 elements (Al, Si, P, S, Cl, K, Ca, Mn, Ti, Fe, Cu, and Zn) were detected with varyi ng degrees of concentration. The plotted element concentration curves favored micron and submicron particle diameters. The particle shapes e xhibit high/low sphericity. The plotted size distribution curves exhib ited a marked downward shift in particle diameter from Kano to Ife.
