Rice is one of the most popular staple food of population. . It can absorb contaminants and heavy metals from the soil and affect human health.. Therefore it is necessary to have information about the heavy metals in rice and intake of them by human. Based on this, heavy metals cadmium, chromium, lead and nickel in rice samples were studied from three sources: Iran, Pakistan, India and atomic absorption spectrophotometer The amount of heavy metals of Cd, Cr, Pb and Ni in various rice samples ranged from 0.04±0.008 to 0.40±0.03, 0.19±0.10 to 0.50±0.0, 0.092±0.04 to 1.28±0.1 and 0.19±0.01 to 0.89±0.01 respectively. The highest total heavy metals was observed in Taj mahal and the lowest in Abdalsalam. Estimated daily intake (EDI) value was calculated for different rice types.The concentration of cadmium and lead were above limit of quantification (LOQ) defined by FAO/WHO except one brand, whilst the chromium amount was significantly lower than LOQ. From recent rice consumption data, the estimated daily intakes of toxic compounds were computed for Iranian population. Estimated daily intake (EDI) for all heavy metals through imported and domestic cultivated rice consumption was considerably lower than the ADI.
