Honey is an important food ingredient due to its nutritive and medicinal values. In this project, varieties of honey samples were collected from different environmental sites in District Bannu. Several spectroscopic techniques were used to determine the composition of a series of trace elements within these samples. Cu, Zn, Al, Fe and Mg composition was determined using flame atomic absorption spectroscopy (FAAS), meanwhile Pb, Ni, Cd and Cr composition was determined by electro-thermal atomic absorption spectroscopy (ETAAS) and graphite atomic absorption spectroscopy (GAAS). Lastly, As, Hg, and Se composition was determined by Hydride generation atomic absorption spectroscopy (HGAAS). The trace elements Al, Zn, Mg, Fe, Cu, Cr, Pb, Cd and Ni were found in considerable abundances. However the amounts of As, Hg and Se were below the detection limits of the instrument ( ≥ 0.1 ppm, ≥ 0.1 ppm and ≥ 0.2 ppm for each element respectively).
