“…For a light water reactor (as the Budapest Research Reactor), using the mean of five values delivered by this reference 32.8 mg of P in the sample gives the same 28 Al activity as 0.01 mg of Al. Picking up the corresponding phosphorus content of our plants from [38–46] can calculate the mean P concentrations (mg/kg), as follows: coriander 4041, dill 1745, Echinacea 2810, lavender 2810, chamomile 3635, mint 4046, plantain 4790, and Tobacco 4630 (from IPE 205) [20]. From these data, the following correction rates can be calculated for each of the plants: 4.07%, 0.34%, 1.80%, 0.01%, 0.33%, 0.13%, 0.06%, and 0.25%, respectively.…”

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.

“…Therefore, the essential and trace elements in food and medicinal plants have been studied by several research groups worldwide (i.e. Chizzola et al, 2008;Del Vitto et al, 2009;Kara, 2009;Martins et al, 2009;Nookabkaew et al, 2006). Moreover, determining the level of minerals can contribute both to an effective quality control and traceability of herbal medicines, and even to establish the safety of its use in terms of levels of toxic elements.…”

It has been determined the concentration of fourteen micro and macrominerals (Al, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, P, Se, and Zn) in both crude drugs and infusions of Melissa officinalis L., Lamiaceae, Nepeta cataria L., Lamiaceae, Passiflora caerulea L., Passifloraceae, Tilia x moltkei Späth ex C.K. Schneid., Tiliaceae, and Valeriana officinalis L., Caprifoliaceae. These herbs are widely consumed by its sedative properties, either alone or in herb mixtures. All measurements were performed using an inductively coupled plasma optical emission spectrometer (ICP-OES). The products were obtained from regional markets, mainly in San Luis province (Argentina). The estimated daily intake was compared with current recommendations. All products and its infusions were included within the upper tolerable limits for minerals, in trace elements such as toxic elements present at low levels.

“…In general, aromatic plants cannot be considered as phytoextractors, not only because most of the accumulated heavy metals are stored in their roots, but also because their biomass is low. These results clearly exclude aromatic plants grown on heavy metal contaminated fields (at least the plants we examined), from either phytoremediation processes, or from consumption as food supplements or herbs, or for herbal teas, as some of their heavy metal content is expected to be extracted to the concoction (Schilcher and Peters 1990;Chizzola et al 2008;Arpadjan et al 2008;Affholder et al 2013). However, careful analysis of the extracted essential oils from plants grown at all the conditions tested showed that neither the quality and the content of the oils were altered significantly, nor detectable amounts of heavy metals were found in these oils.…”

CULTIVATION OF MEDICINAL AND AROMATIC PLANTS IN HEAVY METAL-CONTAMINATED SOILSLYDAKIS-SIMANTIRIS N. ABSTRACTThe growing number of polluted land areas makes the question of rehabilitation and safe/effective use of these areas increasingly imperative. For land polluted by heavy metals, the possibility of transferring the toxic pollutants to humans through the food chain further increases the importance of the safe management of polluted lands. We examined the possibility of using heavy metal-polluted areas for growing specific aromatic plants, which can be used either as food herbs/infusions, or to produce high value products. In a pot experiment, chamomile, sage and thyme plants were exposed to a range of concentrations of Cd, Pb, and Ni in the soil. Toxic metal levels were determined in the roots, leaves and flowers (for chamomile) of the plants. All three plants accumulated relatively high amounts of metals in their roots, whereas the aboveground parts exhibited lower accumulation capacity. Regardless the levels of metal accumulation, the quality of essential oils from chamomile, sage, and thyme was not affected and in all cases the extracted essential oils were free of heavy metals. Our results suggest that the aromatic plants under study cannot be consumed either as food additives or as infusions. However, under strict control of the cultivations, heavy metal-contaminated areas can be used for the production of essential oils from aromatic plants.
