“…This can be attributed to nickel as one of the most mobile and bioavailable heavy metal ions that may be present in both industrially contaminated and pristine soils. 34 The results obtained in this study were in agreement with the study mentioned above since the concentration of Zn (19.7 35 while, in this study, only Ni and Co were quantified. The other elements presented below LOD.…”

In this study, the elemental composition of nine medicinal plants and phytomedicines was evaluated by using axial view inductively coupled plasma optical emission spectrometry (ICP OES) after three digestion procedures: dry ashing (DA) and two wet digestions with a mineral acid (HNO 3 /H 2 O 2 ) mixture on a conventional hot plate (CD), besides microwave digestion (MW). Accuracy was assessed from spinach leaves (CRM 1570a) and recovery values were in the range of 82 to 113.8%. Precisions, such as relative standard deviation (RSD), below 10% were reached. The MW procedure was preferred for its accuracy (recovery values of 94 to 102%), reduced contamination, increase in the efficiency of the decomposition process, lower residual acidity and reduced time required for digestion. The concentrations of analytes in the samples (minimummaximum in μg g ). The levels of Al, Ba, Cd, Cr, Mo, Pb, Se and V in all investigated samples were found to be below the limit of detection of ICP OES. The multielement analysis by ICP OES showed that the method is simple, fast and reliable for the multielement determination in medicinal plants and phytomedicines.

“…To describe the probability of asymmetric datasets, we used medians C med (lit), quartiles (Q 25 , Q 50 and Q 75 ) and concentration minimum C min (lit) and maximum C max (lit) ( Table 2). For all three toxic metals in chamomile (Cd was not detected), the C m (exp) values (Figure 1b) are rather close to C med (lit) ( Table 2) and located within Q 25 or Q 50 of the published distributions. In other words, the studied chamomile samples are among half samples with the lowest concentrations.…”

Objective: To determine concentrations of essential microelements Fe, Cu, Mn and Zn, as well as toxic metals Pb, Cd, Cr and Co, in three herbal remedies and compare the experimental data obtained with available literature data. Materials and Methods: Elemental compositions of three herbal remedies, Chamomile flowers, Urtica folia (nettle) and Hyperichi herba (St John's wort), grown and produced in Ukraine, were studied by flame atomic absorption spectroscopy. Results: The Fe concentration decreases, as well as the Zn and Mn concentrations, increase in going from nettle through chamomile to St John's wort. The Cu content is virtually independent of the plant type. Statistically significant negative correlations between the element concentrations were found in Fe-Mn and Fe-Zn pairs. The studied samples of St John's wort are more contaminated with Cd than other plants, while the highest Pb content is observed in some samples of nettle. Conclusion: The measured levels of both Pb and Cd still secure against overuse of toxic metals with herbal remedies.

“…monitored 12 and our recent investigations found 15 elements in SJW preparations . Due to the lack of Certified Reference Materials (CRMs) available for SJW, a number of plant‐based CRMs have been reported for accuracy assessments including tomato leaves, peach leaves, spinach leaves, tea leaves, mixed Polish herbs, grass and tobacco …”
