Atomic Absorption Spectrophotometry Detection of Microelement in Some Animal Products from Various of Merowe–Sudan

Environmental problems related to pollution of soil, food, and water have been increased with industrialization. The determination of the twenty one microelements performed by atomic absorption spectrometry (AAS) namely (Cadmium, Cobalt, Copper, Manganese, Lead, Iron and Zinc) in some animal products (yoghurt, Poultry and white cheese) that Sold in groceries public in Merowe-city-Sudan. Results indicated high concentration of Zn and Pb especially in white cheese samples. The lowest concentrations of metals were found in yoghurt. Mean metals concentration (mg/kg) in poultry were ND ND (mean Not Detected) for Cd, 0.14 for Co, 0.014 for Cu, 2.28 for Fe, 0.16 for Mn, 2.78 for Zn. Poultry were found to contain significantly more Zn and Fe than yoghurt but generally less Co. Finally, further investigation is needed to identify the cause of elevated Zn and Fe especially in poultry and whit cheese. Data analysis was carried out by the statistical software SPSS as well as Excel to compare heavy metal concentration between different brands
