Abstract
As a result of environmental pollution and food chain, heavy metals may accumulate in human or animal bodies. Toxic metals cause inhibition on chemical and enzyme reactions in cells. Therefore, a negative situation forms in organs and tissues due to their toxic effects. The examination of metal pollution in foods and environment facilitates to monitor their harmful effects on human health. In the proposed study, the concentrations of toxic metals in tissue samples of animal obtained from a local farm were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) following micro-wave digestion. Five different tissue samples were studied including lung, liver, kidney, muscle, and brain. Metals were showed various distribution in the different organs. The highest concentration of Al in the lung, Cu, Mn, and Mo in the liver Cr, As and Se in kidney, and V in kidney and brain were found. The mean values obtained for kidney, liver, lung, muscle and brain of cattle tissues were: 2.40, 2.44, 3.73, 2,90, 3.07 mg/kg Al; 0.35, 0.26, 0.29, 0.27,0.36 mg/kg V; 3.95, 7.00, 0.76, 0.45, 1.19 mg/kg Mn; 15.82, 280.86, 7.94, 3.85, 10.64 mg/kg Cu; 1.87, 4.25, 1.19, 0.15, 0.28 Mo; 0.47, 0.14, 0.10, 0.07, 0.04 mg/kg As; 0.47, 0.33, 0.41, 0.39, 0.43 mg/kg Cr; 4.38, 1.38, 0.82, 0.60, 0.56 mg/kg Se respectively. Certified reference material (NIST CRM 2976 muscle tissue) was analyzed for accuracy of method. This results are good agreement (≥95 %) with the certified values.
