“…Similar to Zn, the high levels of Cu in these plants are the outcome of nearby waste water discharge or irrigation with waste water, and due to pesticides. In fact Cu is a constituent used in pesticides (Tokalioğlu, 2012). A statistical significant correlation (r = 0.62, p < 0.01) occurred between the levels of Zn and Cu in the investigated medicinal herbs.…”

The levels of K, Ca, Fe, Zn, Cu, Mn, Pb, As, Cd, Cr, and Pb in commonly used medicinal herbs and their infusions by Lebanese were analyzed by EDXRF and ASS techniques, respectively. The order of metal contents in the herbs was found to be: K (6990-19850 μg/g) > Ca(1630-14450 μg/g) > Fe(80-3650 μg/g) > Mn (28-458 μg/g) > Zn (23-108 μg/g) > Cu (5-71 μg/g) > Cr (3.1-55 μg/g) Pb> (1.1-10.3 μg/g) > As (nd-10.8 μg/g) > Cd (nd-1.7 μg/g). The mean levels of toxic metals in herbs Pb, As and Cd were below WHO permissible levels. Cluster analysis indicated metals are most probably in plants due to wastes disposal and irrigation with contaminated wastes and/or from atmospheric waste particulates. The levels of Mn, Cr, Pb and As in herbal infusions were found to be higher in soaked than boiled preparations and correlated with Fe, while Zn and Cu levels were higher in boiled infusions. The highest weekly intake from herbal infusions of toxic metals Cr (492.8 μg), As (77.0 μg), Pb (291.2 μg) and Cd (19.0 μg) were below the recommended permissible tolerable weekly intake respectively 1260 μg, 900 μg, 1500 μg, and 150 μg. Therefore, the consumption of these traditional medicinal herbs does not pose any health risk provided full compliance with recommended daily doses.

“…Chromium is an essential micronutrient, but it becomes toxic at high levels, and chronic exposure to Cr may result in liver, kidney and lung damage (Tokalioğlu, 2012). The mean concentration of Cr in investigated herbs was 10.56 μg/g.…”

“…There are no regulations for limits of Pb for particular medicinal herbs, because the content of this metal vary with respect to plant species, geographic region, agronomic treatment etc (7).Many authors in their studies have determined the content of metals in medicinal herbs (21)(22)(23). The content of lead in similar kinds of medicinal herbs, detected in the study of Arpadjan and al.…”

ACTA FACULTATIS MEDICAE NAISSENSISUDC: 631.4:633.88 S U M M A R YMedicinal herbs and their mixtures, which are widely used for prevention and treatment of some disease, can also present health risks due to the presence of toxic metals such as Pb and Cd. The application of different agrotechnical practices during plant growing season, as well as the process of circulation of substances in nature, may be the cause of plant contamination.The aim of this study was to determine the content of lead, cadmium and copper from soil which are bioavailable for absorption by plant, as well as the total content of these metals in some medicinal herbs that were cultivated in two different locations. The presence of these metals in the samples was detected using highly sensitive microanalytical technique potentiometric stripping analysis (PSA).The mean value of lead total content in the analyzed samples of medicinal herbs Chamimillae flos, Urticae folium, Menthae folium, Altheae radix and Basilici herba, which were grown at the sites near the industrial zone, was about 1.55 μg/g, 1.82 μg/g, 1.90 μg/g, 1.99 μg/g and 2.74 μg/g, respectively. Contrary to this, the total content of this toxic metal in the analyzed plant samples grown on rural areas was detected only on some sites.Based on the results of this study, it can be concluded that medicinal herbs contained a certain amount of lead and that its content varied depending on the location at which the plant species were grown as well as on plant affinity to certain metal. Cadmium and copper were not detected in the tested plant material.

“…An AI is given when the RDA cannot be set. Table 7 collects (in mg) the estimated daily intake of Iraqi consumers from Cu (0.192), Zn (0.809), Fe (4.89), Mn (1.07), Cr (0.009), Ni (0.029), and Co (0.004); together with the recommended dietary allowance (RDA) [54] for Cu (0.9), Zn (8)(9)(10)(11), and Fe (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18); the mean intake (AI) for Mn (1.8-2.3) and Cr (0.025-0.035); and the tolerable upper level (TUL) for Ni (1.0). None of the Dietary Reference Intakes (DRIs) were determined for Co due to lack of data of adverse effects and concern with regard to lack of ability to handle excess amounts.…”
