The concentration of the food stuffs by toxic metals is a threat and their exposure for long time has determinate effects on the health tutus of animals. Hen’s eggs and fish are one the main sources of protein but if contaminated by toxic heavy metals will cause a harmful effect on human health. This study aimed to assess the concentration of seven microelements performed by Atomic Absorption Spectrophotometer (AAS). Namely (Cadmium, Cobalt, Copper, Iron, Manganese, Lead, and Zinc) in tow samples of some animal products fresh (fish and hens egg) collected from the district popularly in Merowe-city-North Sudan. Heavy metals in hens eggs and fish samples were analyzed using (AAS) in accordance to standard analytical method data obtained were subjected to statistical analysis (ANOVA). To find out the significant difference of toxic heavy metals in fish sample the obtained results showed the average values Cd and Pb (0.100 and 0.720 mg/kg) respectively in fish sample were higher than permissible limits (p<0.05mg/kg) set by world health organization (WHO). The analysis of heavy metals in fish indicated among seven heavy metals tested, lead showed the highest concentration compered to levels essential elements followed by (0.170 for Co, 0.420 for Cu, 1.910 for Fe, 0.145 for Mn, and 2.685 mg/kg for Zn). Our results also showed that accumulation of heavy metals differed in the hens eggs sample recorded high levels of heavy metals found to Cd and Pb (0.070 and 0.305 mg/kg) respectively. The mean concentrations of essential elements followed (3.335 for Zn, 2.200 for Fe, 0.195 for Cu 0.090 for Co, and 0.070 mg/kg for Mn) respectively. Concentrations in sample of the studied fish showed that there were highly significant different between the Cd and Pb (0.100 and 0.720 m/kg) than hens eggs (0.070 and 0.305mg/kg).
