ABSTRACT / SAŽETAK:
This study presents the determination of cadmium (Cd), copper (Cu), and zinc (Zn) in whole grain rice samples of different geographical origin using microwave digestion followed by ICP-OES analysis. The method was validated in terms of linearity, sensitivity, precision, and accuracy through certified reference material. Cd concentrations were well below regulatory limits, while Cu and Zn levels were consistent with typical nutritional values. The findings confirm both the safety of the analyzed samples and the reliability of the applied analytical methodology.
The results indicate that there is no significant toxicological risk associated with the analyzed samples, and they confirm the effectiveness of ICP-OES for reliable monitoring of trace metals in Italian rice. Continuous surveillance is essential due to rice’s high consumption rates and its ability to accumulate metals.
