Sažetak
Both essential and heavy metals play important roles in human health and diseases. The aim of the present study was to determinate concentrations of essential and heavy metals, such as Na, K, Ca, Mg, Cu, Cr, Mn, Ni, Fe, Pb, Zn, and Cd, in the leaves of Mentha longifolia L. and Mentha × piperita L. The plant material samples were collected from six different locations in Bosnia and Herzegovina (B&H), at selected distances from heavy metal pollution sources. Wet digestion was applied for the dissolution of samples and essential and heavy metals concentrations were analysed by flame atomic absorption spectrometry and (FAAS). Results of the analysis (expressed as mg g–1) were obtained as follows: Na 2.08–4.12; K 14.85–22.54; Ca 9.06–15.53; Mg 1.93–3.12; Cu 0.01–0.05; Cr 0.70–0.90; Mn 0.02–0.09; Ni 1.10–7.00; Fe 0.06–1.11; Pb 0.10–0.90; Zn 0.01–0.04. The cadmium concentration in all samples was below the detection limit by FAAS. Strong correlation between Ni and Pb, as well as Ni and Fe, confirmed mostly environmental and processing influence/impact. In conclusion, Mentha longifolia L. and Mentha × piperita L. can be used in daily consumption considering the high content of essential metals Fe, Cu, Mg, and Zn, and their beneficial effects on normal body function. In addition, there is no risk of heavy metals to human health after consuming these samples due to lower concentrations.
