Abstract

The safety of the cereal products is of high nutritional and toxicological interest, since the cereal industry and its products have a big economic and social importance worldwide. In this pilot research the presence and the content of toxic trace elements arsenic, cadmium and lead in three samples of rice: 11,67+5,69mg/kg, 25,67+6,43mg/kg, 47,67+18,01mg/kg for As, Cd and Pb respectively, wheat flour: 7+5mg/kg, 9+1,73mg/kg, 69,92+16,92mg/kg and flour products (bread: 9,33+2,08mg/kg, 6,67+0,58mg/kg, 36+3,6mg/kg, pasta: 1,61+1,15mg/kg, 2,67+2,08mg/kg, 30+7mg/kg and tea biscuits: 4,67+4,04mg/kg, 1,33+0,58mg/kg, 53+9,64mg/kg for As, Cd and Pb respectively) produced by three different manufacturers from Macedonia was determined by applying the hydride generation and electrothermal atomic absorption spectrometry with wet digestion. In this research the contribution to the average daily intake for toxic elements through daily intake of cereal and cereal products (20% of the all-day meal) has been determined. The contribution of As (9,86%), Cd (10,02%) and Pb (11,39%) compared to the average daily intake and the PTDI was low, which indicates that these products are safe for consumption concerning the examined toxic elements. The levels of the toxic elements in the samples of Macedonian rice, wheat flour, bread, pasta and tea biscuits are comparable to those obtained from various parts of the world and their consumption does not pose any health risks.
