TM concentrations were determined using inductively coupled plasma mass spectroscopy (ICP-MS). Two standard reference materials, CTA-VTL-2 (Virginia tobacco leaves) and BCR 141R (calcareous loam soil), provided by the European Union Commission in Poland andBelgium, respectively, were analyzed. The values obtained were in good agreement (within 5%) with the certified concentrations, confirming the reliability of our analytical procedure.
