Abstract
Cereals are the main source of food in many countries. Iron, Magnesium, Copper and Chromium metals were determined. Cereal samples was digested using HCl and HNO3 and the metals were determined using atomic absorption spectroscopy (AAS) and results indicates that the amount of metals in cereals is as follows wheat>Barely>maize> bean in average whereas in specific amounts, the amount of metal, Fe, Mg, Cu and Cr in wheat (18.28 ± 0.032, 18.55 ± 0.005, 18.01± 0.034 and ND), in barely (17.75 ± 0.037, 17.35 ± 0.015, 17.02± 0.045 and ND),in maize (16.35 ± 0.065, 13.12 ± 0.025, 7.05 ± 0.027 and ND), in bean (14.72 ± 0.062, 14.36 ± 0.054, 6.02 ± 0.014 and ND) respective, chromium did not detected in all cereals and the % recovery of the instrument for all metals is in between 90-102 %.Generally the amount of trace metals that was obtained in this research was in the acceptable range.
