“…Lead accumulation impedes the growth and development of crop plant due to lower uptake of essential minerals (Gopal and Rizvi, 2008). The growth inhibition under Pb stress was similar to that previously described by Jezler et al (2015) in Mentha arvensis. Lead concentration decreased the stem girth, root length; fresh and dry weight of 12 weeks old cassava varieties (Ano et al, 2013).…”

Chenopods are known for salt and metal ion tolerance. Chenopodium quinoa is a recent introduction in the country but yet to be tested on metal contaminated soils. A pot experiment was conducted to explore growth and phytoextraction potential of four quinoa lines (A1, A2, A7 and A9) against different lead concentrations (0, 50 and 100 mg kg -1 ). Required lead concentrations were developed in polythene bags filled with sandy loam soil (5 kg) using lead nitrate salt prior to two month sowing and kept sealed up to sowing. Fifteen seeds of each quinoa lines were sown in each treatment bags with three replications. Five plants were kept in each bag after their complete emergence and allowed to grow till yield production (120 days). Results showed that translocation of lead increased from roots to shoots with increase in soil lead concentration in all lines with the following trend: A1>A9>A7>A2. However, A1 accumulated higher in leaf compared to other lines as depicted by translocation factor of 2.34 and 1.34 when grown at soil having 50 and 100 lead mg/kg, respectively. This trend was similar in case of root (A1>A9>A7>A2). There was 25-66% decline in seed yield at 50 mg kg -1 lead level in all lines compared to control. However, growth and yield declined with further increase in lead level. The maximum reduction in yield was observed in A7. More importantly lead concentrations in seed of A2 and A7 quinoa lines were within the permissible value set (0.3 mg/kg DW) by FAO/WHO. It can be concluded that quinoa is suitable for phytoextraction and despite hyper accumulation the concentration in seed remains within safe limit for human consumption.

“…Moreover, little is known about the ultrastructure of root cells exposed to Cd. There are only a few studies reporting the effect of Cd on the root plastids [25] or on the ultrastructure of the root meristematic cells [26,27], whereas most studies describe the alterations of the ultrastructure of leaves caused by Cd application [21,26,27,28,29,30,31]. It should also be stressed that most literature on this topic focuses on seedlings, mostly 7 [14,16] or 14 days old [13,21], while our study was to analyze older plants (four weeks old).…”

The analysis of the effects of cadmium (Cd) on plant cells is crucial to understand defense mechanisms and adaptation strategies of plants against Cd toxicity. In this study, we examined stress-related enzyme activities after one and seven days of Cd application and the ultrastructure of roots of Pisum sativum L. after seven days of Cd treatment (10, 50, 100, and 200 μM CdSO4). Our results showed that phenylalanine ammonia-lyase (PAL) activity and the amount of Cd accumulated in the roots were significantly positively correlated with the Cd concentration used in our experiment. However, Cd caused a decrease of all studied antioxidative enzyme activities (i.e., catalase (CAT), ascorbate peroxidase (APX), guaiacol peroxidase (GPX)). The analysis of the ultrastructure (TEM) showed various responses to Cd, depending on Cd concentrations. In general, lower Cd concentrations (50 and 100 μM CdSO4) mostly resulted in increased amounts of oil bodies, plastolysomes and the accumulation of starch granules in plastids. Meanwhile, roots treated with a higher concentration of Cd (200 μM CdSO4) additionally triggered protective responses such as an increased deposition of suberin lamellae in the endodermal cell walls. This indicates that Cd induces a complex defense response in root tissues.

“…Non-essential and toxic elements Pb and Ni were present almost in the same levels in both tested samples of Mentha species. 7,12,17,23,24 In addition, in all samples, the measured content of Pb was significantly below recommended value of 10 mg kg −1 (WHO). 19,21…”

“…Relatively low content of Cu in wild samples compared to the content of Zn is due to the fact that higher Cu concentrations mean lower Zn content, because higher concentrations of Cu in the soil relative to Zn can reduce the availability of Zn to a plant, due to competition for the same sites for absorption into the plant root. [23][24][25] In cultivated herb samples (Table 2), no Cd was detected in all three samples, while the highest concentration was detected for Fe and the lowest concentrations for Pb. 24 The detected high concentrations of Fe and Zn in the samples of cultivated species of Mentha confirmed the results of previous published papers that the deficiency of Zn leads to a deficiency of Fe in plants.…”

Both essential and heavy metals play important roles in human health and diseases. The aim of the present study was to determinate concentrations of essential and heavy metals, such as Na, K, Ca, Mg, Cu, Cr, Mn, Ni, Fe, Pb, Zn, and Cd, in the leaves of Mentha longifolia L. and Mentha × piperita L. The plant material samples were collected from six different locations in Bosnia and Herzegovina (B&H), at selected distances from heavy metal pollution sources. Wet digestion was applied for the dissolution of samples and essential and heavy metals concentrations were analysed by flame atomic absorption spectrometry and (FAAS). Results of the analysis (expressed as mg g–1) were obtained as follows: Na 2.08–4.12; K 14.85–22.54; Ca 9.06–15.53; Mg 1.93–3.12; Cu 0.01–0.05; Cr 0.70–0.90; Mn 0.02–0.09; Ni 1.10–7.00; Fe 0.06–1.11; Pb 0.10–0.90; Zn 0.01–0.04. The cadmium concentration in all samples was below the detection limit by FAAS. Strong correlation between Ni and Pb, as well as Ni and Fe, confirmed mostly environmental and processing influence/impact. In conclusion, Mentha longifolia L. and Mentha × piperita L. can be used in daily consumption considering the high content of essential metals Fe, Cu, Mg, and Zn, and their beneficial effects on normal body function. In addition, there is no risk of heavy metals to human health after consuming these samples due to lower concentrations.
