“…All these forms of pharmaceuticals based on plants are included in the category of nutritional supplements, which are not a subject to strict control. Although medicinal plants are considered harmless by ordinary people, a closer look at the risk of accumulation and control of toxic metals or undesirable elements, evaluating content items is justified and desirable to be a criterion for their use [3, 4]. If the medicinal plants are harvested from the spontaneous flora, they may be contaminated by heavy metals [5, 6] because of where they were gathered.…”

The metallic elements concentrations of medicinal plants (coriander, dill, Echinacea, lavender, chamomile, mint, and plantain, used for phytopharmaceutical products), cultivated in unpolluted region, were analyzed by neutron activation analysis. The essential nutrients, macro-, micro-, and trace elements (K, Ca, Mg, Na, Fe, Mn, Rb, Sr, and Zn), potentially toxic elements (Al, As, Ba, Co, Sb, Cr, and V), and rare earth elements were monitored and were compared with those presented in the literature. An estimation of their contributions to intake and toxicity for a person was made, which revealed that (a) teas prepared from the examined plants represent useful contribution to the food provided intake of three essential macronutrients (K, Ca, and Mg); (b) the Cu, Mn, Rb, Sr, Zn, and rare earths levels are normal or low; (c) the quantities of As, Ba, Co, Sb, Cr, and V do not represent toxicological concerns; (d) the examination of the estimated Al and Fe quantities recovered in infusions in the conditions of usual daily tea consumption is below the Tolerable Daily Intake values. The strategy of cultivation of medicinal plants in unpolluted areas is efficient and beneficial. However, individual plants ability to concentrate preferentially certain elements suggests controlling the contamination level of raw materials.

“…Fruits and vegetables are an important component of human diet as they are major sources of various nutrients such as vitamins, fibers, sugars, carbohydrates, and essential minerals that are useful for human health [1][2][3][4][5][6][7][8][9][10][11][12]. Several studies have shown that fruits and vegetables consumption are significantly reduce the risk of several chronic ailments such as cancer, heart disease, and stroke [9,[13][14][15][16].…”

“…However, the consumption of dried fruits contaminated with toxic heavy metals may result in a serious risk to human health [8,17,25]. In recent years, there is an increasing concern about human exposure to toxic heavy metals as a serious health and environmental problem overall the world [1,7,[26][27][28][29][30][31][32]. Human exposure to heavy metals has largely increased as a result of rapid urban and industrial developments [6,10,29,33,34].…”

“…Heavy metals are commonly classified into two types; essential heavy metals and toxic heavy metals. The first type contains heavy metals that are essential and necessary for human biochemical processes such as iron (Fe), copper (Cu), vanadium (V), zinc (Zn), selenium (Se), cobalt (Co), manganese (Mn), chromium (Cr 2+ ), magnesium (Mg), or molybdenum (Mo) [1,2,7,10,11,27,28,30,35,36]. However, excessive levels of these metals in foodstuffs can be toxic and have adverse effects on the human health [8,9,17,25,37].…”

In the present study, the concentrations of nine heavy metals (Fe, Zn, Mn, Cu, Mg, Cr, Ni, Cd, and Pb) in six different imported dried fruit samples of different brands (Mangoes, black raisins, figs, apricots, plums, and cranberries) were determined by Flame Atomic Absorption Spectroscopy (FAAS) after wet digestion. Samples were collected from different stores in Amman, Jordan. The average concentration of the selected metals in the analyzed samples were found to be in the range of 1.70-8.70 (Fe), 0.15-0.72 (Zn), 0.09-0.59 (Mn), 0.07-0.46 (Cu), 2.5-53.4 (Mg), 0.06-0.15 (Cr), 0.17-0.29 (Ni), 0.01-0.05 (Cd), and 0.11-0.57 (Pb) µg/g. The highest concentrations of Fe, Zn, Mn, Mg, and Ni were found in dried figs, highest concentrations of Cr, Cd, and Pb were found in dried apricots, and highest concentrations of Cu was found in dried black raisins. The results obtained in this study showed that Mg and Fe have the highest concentrations in all analyzed samples, whereas, the lowest concentrations obtained were for Cd and Cr. The concentrations of the highly toxic metals (Pb and Cd) in the all analyzed samples were found to be below or in good agreement with the permissible limits set by different health organizations. The figures of merit obtained for the FAAS calibration curves are brilliant with good linearity (r2 > 0.99). The FAAS method was validated by determining limit of detection (LOD), limit of quantitation (LOQ), and percent recovery (%R) for all investigated metals. The results obtained in this work were compared with the literature reported values.

The present study focused on different brands of chewing food products which containing some toxic metals (TMs) and essential metals and these samples were analyzed to determine the levels of some toxic metals (Pb, Cd, Ni, Cr and Mn) and essential metals (Ca, Cu, Fe, K, Mg, Na and Zn). The samples of gutka (100), sweet supari (63), sweet paan (16) and paan masala (21) were randomly collected from different shops of Karachi, Pakistan. The validity of conventional wet acid digestion method (CAD) was assessed by analyzing two certified reference materials (CRM) Virgina tobacco leaf (CTA-VTL-2) and Bovine liver (1577b) and standard addition recovery test. The limit of detections (LODs, n=10) of the method were found to be 0.144, 14.4, 8.89, 2.76, 4.06, 15.3 and 2.99, 22.9, 9.97, 4.54, 1.89, 1.76 µg L -1 for Ca, Cu, Fe, K, Mg, Na, Zn, Cd, Cr, Mn, Ni and Pb, respectively. The CAD method was successfully applied to real samples for the determination of toxic and essential metals.
