| Abstract | |
Concentrations of As, Cd, Co, Cu, Mn, Pb, Se and Zn were determined in polished and husked rice samples purchased from Singapore markets to estimate nutritional risk by their estimated weekly intakes (EWIs). The elemental distribution in rice grain was studied using scanning electron microscopy coupled with energydispersive X-ray spectroscopy (SEM-EDS), and a principal component analysis was performed to investigate the relationships between the variables (total element concentration) in a multidimensional space. Except for Cd and Se, the median concentration of analytes for husked grains was higher than in polished grains. Rice samples with As concentration higher than 198 mu g kg-1 were submitted to speciation analysis, and inorganic-As found in grains ranged from 41 to 87 % of the total As. Calculated EWIs for essential elements were lower than the Recommended Dietary Allowance, while the EWIs for non-essential elements were below the Provisional Tolerable Weekly Intake. Nevertheless, our results demonstrate that the presence of toxic elements in rice, especially As, must be carefully monitored. It was found a significantly low concentration levels of essential elements in most of the samples analyzed, highlighting the relevance of biofortification strategies to mitigate hidden hunger. Furthermore, the mineral profile obtained from the samples allowed discrimination of rice samples according to farming practice, grain processing and country of origin using principal component analysis and discriminant function analysis.
