SummaryThe levels of essential (Ca, Mg, Fe, Zn, Cu, Co, Cr, Mn and Ni) and non-essential (Cd and Pb) metals were determined by flame atomic absorption spectrometry in samples of korarima (Aframomum corrorima) seeds and the corresponding soils collected from southern and southwestern Ethiopia. A wet digestion procedure involving the use of 3 mL of HNO3 (69-72%) and 1 mL of HClO4 (70%) were used to solubilize the metals from the korarima seed samples, and a modified aqua regia (HCl:HNO3) reagent with added hydrogen peroxide (6 mL of aqua regia and 1.5 mL of H2O2) was used for the soil samples. The levels of the nutrients in the korarima seed samples were in the following ranges: Ca (1794-2181); Mg (1626-2067); Mn (141-180); Fe (37-46); Zn (12-18); Ni (6.6-8.5); Cu (5.8-8.3); Cr (3.8-5.8) and Co (2.0-2.3) in µg g–1, respectively. The concentration of non-essential cadmium was in the range from 0.9-1 µg g–1 while that of lead was below the detection limit of the method. There was good correlation between the levels of some metals (Ni, Fe, Cd, Ca, Cu, Mg) in the korarima seeds and soil samples but poor correlation between other metals (Cr, Zn, Mn, Co)
