ABSTRACT: Cadmium is a toxic heavy metal. It enters soil through air and polluted water and sewages. Cadmium can accumulate in the human body, so WHO hast set permitted levels for weekly consumption of cadmium containing foods (PTWI). Rice is one of the staple foods all over the world. Daily consumption of rice cultivated in soils with high levels of cadmium can impose serious hazards for humans. In this study five rice samples from five different major rice producing cities of Khuzestan province were evaluated using ICP/MS. Results showed that in 4 sample cadmium levels were higher than permitted level by WHO/FAO (more than 1?g/kg.body weight. Day).
