“…Similarly, they were found that Cu and Pb in S. nigrum and Cu, Ni, and Zn in W. somnifera collected from the nearby agricultural area (Samandag-Karacay) were above the permissible limits, while the other metals were within normal limits. For R. chalepensis , the concentrations of Cd and Pb metals were measured from different locations in Ethiopia and Jordan, and the studies suggested that the mean values of Cd (0.58–0.71) and Pb (22.8) mg kg −1 were above normal limits in the samples from industrial and agricultural areas [ 139 , 140 ]. However, it was found that only Fe accumulations in R. chalepensis collected from the nearby industrial area (Belen) were above the permissible limits, while the other metals were within the permissible limits in our study.…”

Heavy metal accumulation in medicinal plants has increased dramatically in recent years due to agricultural and industrial activities leading to pollution of natural sources. This study is focused on the concentration of trace elements and heavy metals in aboveground parts of 33 medicinal plants from the Eastern Mediterranean of Turkey. Results showed that the Al concentrations varied between 4.368 and 1104.627, the B level varied between 47.850 and 271.479, Ca values ranged between 1971.213 and 22,642.895, Cd concentrations ranged between 0.011 and 0.651, Cr contents varied between 1.371 and 41.692, Cu values varied between 13.278 and 42.586, Fe concentrations varied between 20.705 and 1276.783, K levels ranged between 652.143 and 14,440.946, Mg concentrations varied from 336.871 to 1869.486, Mn contents varied between 46.383 and 849.492, Na concentrations varied between 167.144 and 3401.252, Ni values varied between 0.065 and 9.968, Pb levels ranged between 1.311 and 16.238, and Zn concentrations ranged between 67.250 and 281.954 mg kg −1 , respectively. Furthermore, Recommended Dietary Allowance (RDA) values for trace elements and estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI) for heavy metals were calculated. The concentrations of heavy metals in some studied plants distributed in industrial and mining regions were found as slightly higher than the acceptable limits determined by WHO. Consequently, in order to prevent this heavy metal accumulation, when collecting medicinal aromatic plants, rural areas, close to clean rivers, or mountainous areas should be preferred, away from highway, mining, and industrial areas.

“…Concentration of lead above permissible limits in medicinal plants and herbs has been reported in previous studies. Example of such is medicinal herbs in Jordan which were found to be 13.9, 13.1, and 16.9 mg Pb/kg on a dry weight basis, respectively [ 40 ]. Pb content of Gunnera perpensa , a medicinal plant from Mabandla Village, KwaZulu-Natal Province, South Africa, has been reported to have values above the permissible limit set by FAO/WHO [ 36 ] in edible plants [ 41 ].…”

FAAS was used for the analysis of trace metals in fresh and dry plant parts of Cymbopogon validus and Hyparrhenia hirta species with the aim of determining the trace metals concentrations in selected traditional plants consumed in Eastern Cape, South Africa. The trace metal concentration (mg/kg) in the samples of dry Cymbopogon validus leaves (DCVL) showed Cu of 12.40 ± 1.000; Zn of 2.42 ± 0.401; Fe of 2.50 ± 0.410; Mn of 1.31 ± 0.210; Pb of 3.36 ± 0.401 mg/kg, while the samples of fresh Hyparrhenia hirta flowers (FHHF) gave Cu of 9.77 ± 0.610; Zn of 0.70 ± 0.200; Fe of 2.11 ± 0.200; Mn of 1.15 ± 0.080; Pb of 3.15 ± 0.100 mg/kg. Abundance of metal concentrations follows the order: Cu > Fe > Pb > Mn > Zn in the flower samples of Cymbopogon validus and Hyparrhenia hirta species. The concentrations of trace metals in both plant parts were below the permissible limits (PL) set by WHO. It is suggested that pharmacovigilance be carried out periodically to improve the quality, safety, and efficiency of various herbal products.

“…Toxic heavy metals, such as Mercury (Hg), Cadmium (Cd), Lead (Pb), Chromium (Cr), Tin (Sn), Nickel (Ni) or Arsenic (As) are hazardous environmental pollutants that are known to have an adverse impact on human health [1][2][3][4][5] . On the other hand, other elements like Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Manganese (Mn), Magnesium (Mg) or Molybdenum (Mo) are important for human health as essential micronutrients and can be toxic if present in excess [6,7] .…”

“…Therefore, they have the tendency to accumulate in different media, such as the human body, soils, surface water, plants and foods. Consequently, they can impair normal development and important biochemical processes, leading to harmful effects on human health [3,6,[12][13][14] . In recent years, human exposure to heavy metals has largely increased as a result of using these metals as raw materials in different industries as well as due to rapid industrialization and urbanization [14][15][16] .…”

“…In Jordan, several environmental studies have been performed to investigate heavy metal pollution in a wide variety of environmental samples, such as roadside soils, street dust, plants, air and agriculture soils [6,9,10,[17][18][19][22][23][24][28][29][30][31][32][33][34] . Most of these studies confirmed that the anthropogenic activities (e.g.…”

In this study, the concentrations of selected heavy metals (Al, Cd, Cr, Cu, Mn, Pb, Co, Fe, Ni, V and Zn) in roadside soil samples were determined by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) after microwave digestion. A total of sixty roadside soil samples were collected during July 2018 from seventeen sampling sites (5 km apart) from both sides along Irbid-Amman highway, Jordan. The average concentrations (±SD) of the investigated metals in the analyzed soil samples were found to be 18400 (± 11200), 6.0 (± 4.7), 132 (± 47), 49 (± 26), 695 (± 310), 96 (± 53), 78 (± 32), 31800 (± 12600), 116 (± 67), 141 (± 74) and 129 (± 112) µg/g for Al, Cd, Cr, Cu, Mn, Pb, Co, Fe, Ni, V and Zn, respectively. With exception of Mn, the enrichment factors for the investigated metals in roadside soils were found to be more than 10, indicating anthropogenic sources such as automobile traffic. In the absence of any industrial activities in the sampling sites, the high concentrations of the investigated metals suggest that automobile emissions are the major source of roadside soil pollution. The results obtained in this study showed that metal concentrations in the analyzed soil samples are strongly influenced by the wind direction and traffic density in the investigated area. The higher metal concentrations on the west side of the road were due to the easterly prevailing wind in the studied area. As expected, the concentrations of heavy metals decreased with increasing distance from the edge of the road. The results obtained in this work were compared with the literature values.
