The paper aimed to identify and assay the selected elements Mn, Fe, Cu, Zn, and Pb in the teas
Agrimony (both in infusion bags and loose leaves), Pigi Tea, and Green Tea with added jasmine, both
in the original raw teas and their infusions. The utility and usability of the chelating extraction
membranes Empore, which were employed to process the liquid samples (infusions), were verified.
The evaluation of the composition of the content was carried out by means of radionuclide X-ray
fluorescence analysis, which is suitable for the identification and determination of samples with
Z>18. Ash contentwas assayed as well.The contents of the heavy metals under study did not exceed
the limits required by the standard.
