“…The current study found that the Cd concentration level (0.35 mg/kg) in this popular species of tea herb exceeded the WHO RMPPL of 0.3 mg/kg [45,70]. Additionally, the WHO [71] recommends that medicinal plants used for various herbal formulations (teas, tinctures, etc.)…”

“…Additionally, the WHO [71] recommends that medicinal plants used for various herbal formulations (teas, tinctures, etc.) should be evaluated for the presence of heavy metals [70]. The RMPPL of toxic metals are set at 1 mg/kg for As and 10 mg/kg for Pb [28,71].…”

“…Consuming tea from HTAs to meet the RDA for Mo is not recommended. Mo has a very limited number of studies focused on tea [70] and needs further characterization and research. Similar to the collective calculation of RDI or RDA and ULs, the HTA and LTA findings were below all guideline categories.…”

This study reports on the harvesting, ingestion, and contamination of American Indian tea Thelesperma megapotamicum grown on the Navajo Reservation in New Mexico. Uranium (U) and co-metal(loid)s (As, Cd, Cs, Mo, Pb, Se, Th, and V) have contaminated local soil and plants. Tea plants were gathered for analysis near U mining impacted areas. The study collected samples of wild tea plants (n = 14), roots (n = 14), and soil (n = 12) that were analyzed with inductively coupled plasma mass spectrometry. Tea harvesting activities, behavior, and ingestion information were collected via questionnaires. Harvesting took place in community fields and near roadways. Results indicate edible foliage concentration levels for Cd exceeded the World Health Organization (WHO) raw medicinal plant permissible level guidelines. Tea samples collected near high traffic areas had significantly greater Cd and Mo concentrations than those collected near low traffic areas (p < 0.001). Tea sample metal(loid) concentration levels ranged from 0.019–7.916 mg/kg. When compared to established food guidelines including the WHO provisional tolerable weekly intake (PTWI), reference dietary intake, recommended dietary allowance, and the tolerable upper limit (UL), Cd exceeded the WHO guidelines but none exceeded the PTWI nor the UL. These findings warrant improved standardization and establishment of universal guidelines for metal(loid) intake in food.

“…This species has not yet been used in comprehensive studies assessing metal accumulation potential on contaminated soils. Several studies are available on the related Matricaria species, primarily on Matricaria chamomilla and Matricaria recutita (Armendaríz et al 2014;Stanojkovic-Sebic et al 2015). With regards to applicability in phytoextraction, M. recutita was found to be a useful metal accumulator species (Radulescu et al 2013).…”

Remediation with plants is a technology used to decrease soil or water contamination. In this study we assessed the remediation potential of two weed species (Chenopodium album and Tripleurospermum inodorum) in a moderately metal-contaminated area. Metal concentrations were studied in roots, stems and leaves, in order to assess correlations in metal concentrations between those in soil and plants. Furthermore, we calculated bioaccumulation factor (BAF), bioconcentration factor (BCF) and translocation factor (TF) values to study the accumulation of metals from soil to plants and translocation within plants. We found correlation in metal concentrations between soil and plants. The metal accumulation potential was low in both species, indicating low BAF and BCF values. In contrast, high TF values were found for Mn, Ni, Sr, Zn, Ba, Fe, Cu and Pb in C. album, and for Fe, Mn, Ni, Zn and Sr in T. inodorum. Our results demonstrated that the potential of C. album and T. inodorum might be limited in phytoextraction processes; however, when accumulated, metals are successfully transported to aboveground plant organs. Thus, to achieve the efficient remediation of metal-contaminated soils, removal of the aboveground plant organs is recommended, by which soil disturbance can also be avoided.

“…The human body requires trace elements in very minute quantities to maintain good health, proper body functions, and development [9,10]. It gets translocated to human through the use of medicinal plants grown in contaminated environments, in which, soils, water, and air contain high concentration of heavy metals [11][12][13][14].…”

Objective: The objective of this study was to determine heavy metals using inductively coupled plasma mass spectrometry (ICP-MS) and phytochemical constituents of methanol extract of Caesalpinia bonducella seed kernel using gas chromatography - mass spectrometry (GC-MS). Methods: In GC-MS investigation, 95% methanol extract of C. bonducella seed kernel was performed on JEOL GC MATE ΙΙ, column HP 5 MS, and Quadruple, double-focusing mass analyzer. Determination of heavy metals from C. bonducella powder was performed using Thermo scientific I CAP Q instrument, for plant powder digestion Anton Paar Microwave model: Multiwave 300 was used. Antimicrobial activity was evaluated using microdilutions broth method. Results: GC-MS analysis of methanol extract of C. bonducella seed kernel has shown 11 different phytoconstituents. ICP-MS analysis has shown the concentration of ten heavy metals in C. bonducella seed kernel as follows: Cr 1.5 ppm, Fe 72.72 ppm, Co 0.33 ppm, Ni 0.03 ppm, Cu 10.73 ppm, Zn 18.44 ppm, As 0.03 ppm, Cd 0.02 ppm, and Pb 0.58 ppm. Conclusion: Result showed that the plant is safe to use from toxic heavy metals such as As, Cd, and Pb. It is suitable to check frequently the heavy metal content in the plant used in traditional medicines before given to patients.
