  The concentrations of essential metals (Ca, Mg, Cr, Cu, Fe, Mn, Ni, and Zn) and non-essential metals (Cd and Pb) were determined in Ethiopian white rice cultivated in Fogera, Metema, and Pawe areas with their corresponding growing soils. The amounts of metals in rice and soil were determined by flame atomic absorption spectrometry, after digesting the powdered rice and soil samples with a mixture of HNO3, HClO4, and H2O2. The accuracy of the digestion procedure was assessed using the spiking method, where an acceptable percentage metal recovery was obtained in the range of 86.6%-106.7% and 87.15%-112.8% for rice and soil, respectively. The concentrations (mg/kg) of metals found in rice and soil, respectively, were in the ranges of Mg 414.28-560.89, 618.70-709.43; Fe 49.36-167.95, 11673.60-12916.67; Ca 45.21-57.71, 281.60-655.20; Mn 27.40-57...
