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.
