Trace metals and mineralogical composition of harmattan dust haze was carried out on samples collected at Ilorin (80 32'N, 40 34'E) a guinea Savanna African City located at the central state of Nigeria. These dusts were gathered at different locations using clean Petri-dishes and plastic bowls of 10cm in diameter. These were analyzed using X-ray Florescence (XRF) and Particle Induce X-ray Emission (PIXE) machine. The average concentration of the metals was (13351.75±45) mg/kg and minerals (7.22%).The mean soil content of the total size of particles for the harmattan season for the station was calculated to be1.79765 μg/m. In conclusion, it was observed that harmattan dusts that blow across Nigeria predominantly comprise quartz and high elements.
