Assessing the Appearance of specific metals in select food samples via flame atomic absorption spectroscopy using multi-acidic solutions digestion (MASD)

Different life style make people depends on definite type of food without a balanced dietary sources which may cause many diseases. So, it is necessary to determine the concentration of these metals in its real samples as food source for different life style to can connect between type of food intake (life style) and the concentration of its metal in it which can predict the diseases which each category of life style will be suffer from. Six heavy metals ions (Fe(III), Cd(II), Cu(II), Ni(II), Pb(II) and Cr(III)) were detected in some real samples as plant, fish and animal samples. All were digested via acidic digestion (MASD) method to identify using flame atomic absorption spectroscopy due to it is highly accurate, sensitive and capable of detecting metallic components in minute concentrations. The greatest concentrations of iron ranged from 15.750 to 0.255ppm in lung tissues, whereas lead concentrations varied from 0.689 to 0.073 ppm in eye tissue. The concentration of chromium ranged from 0.024 to 0.700 ppm in oral tissues, while copper was from 0.109 to 0.021 ppm, with the maximum quantity deposited in lung tissue. In addition to amount of nickel was from 0.284 to 0.198 ppm in brain tissue. Finally, cadmium level ranged between 0.038 and 1.094 ppm. The highest concentration was found in meat tissues. No presence for lead in rice and nigella sativa. A polluted environment may result in the buildup of most metals in bovine lung tissues. Many statistical analyses were conducted using ANOVA Single Factor with mean, standard deviations, p-value. Some statistical parameters were discussed as recommended daily allowances (RDA) and others.
