Abstract
Objective: this research investigates the concentration of heavy metal (Pb, Fe, Cu, Cd and Zn) bio accumulation in cardiac tissue in samples taken from areas near oil fields and brick factories. Method: Atomic absorption spectrometry analysis of powdered, air-dried, acid-digested materials to determine lead, cadmium, zinc, iron, and copper concentrations. Results: The result showed that Zn and Cd were within normal range for samples from both studied areas. Whereas, Cu and Fe with high concentration, Pb in the other hand result showed the concentration of the mineral in samples form brick factories where within normal limits while in samples from oil fields were above the normal limits. Furthermore, the concentration was higher in samples taken from oil fields than those of the brick factories. Conclusion: It has been shown that some of these metals were estimated within normal concentration a further investigation on another animals and human are recommended to consider these metals are safe and are not considered as hazard to human health. In contrast other metals were estimated with high concentration that reported by other studies to be hazard on human health.
