چکیده :

reads are among the most important elements of our daily diet. Knowing about the heavy and essential elements content in bread is required for different purposes such as estimating accumulation of major and trace elements in the bread that may influence water, soil, air, and environment quality as well as the role of bread in nutrition. This study focuses on content of elements such as As, Hg, Cd, Pb, Ni, Fe, Cu and Zn in Bread products available in Shahrekord, Iran. Totally 40 bread samples were collected in January 2014. The mean concentrations of As, Hg, Cd, Pb, Ni, Fe, Cu and Zn in bread samples were 12.5±0, 4.38±0, 9.48±4.75, 931.25±722.5, 98.03±26.89, 2324.69±248, 14276.69±10100.79 and 30316.88±6802.19 µg/kg, respectively. In addition, the concentration of the lead was higher than maximum allowable concentration that probably it is associated to activities of industrial factories around the farms and machine activities.
