ABSTRACT / САЖЕТАК:
Rice (Oryza sativa L.) is a staple food consumed globally and can be a potential source of both essential and toxic trace elements. This study examines the concentrations of cadmium (Cd), copper (Cu), and zinc (Zn) in three Italian rice varieties (P1 – Sushi, P2 – Long-grain, P3 – Risotto) using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) after microwave-assisted digestion.
The analytical method was validated for linearity (R² > 0.99), limits of detection (LOD) and quantification (LOQ), precision, and recovery (91-105 %) using certified reference material.
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.
