“…In our earlier work (Augustynowicz et al 2014 ), we demonstrated the different accumulation patterns of Cr in Callitriche mature leaves and stems incubated both in Cr(III) and Cr(VI) solutions. In the present paper, we focus on the differences between the young and mature organs.…”

“…After treatment with Cr(VI)- and Cr(III)-containing media the plant samples were prepared according to a freeze-drying protocol to avoid the dehydration and redistribution of Cr ions during prolonged μXRF measurements (Augustynowicz et al 2014 ). The spatial distribution of chromium was investigated with a laboratory micro-XRF spectrometer (Wróbel et al 2012 ).…”

The aims of this study were both the qualitative and quantitative analysis of chromium accumulation in the shoots of Callitriche cophocarpa. This globally distributed, submersed macrophyte exhibits outstanding Cr phytoremediation capacity in an aquatic environment. Cr was applied separately for 7 days at two stable forms as Cr(VI) and Cr(III), known from their diverse physicochemical properties and toxicities. The maps of Cr depositions in young leaves, mature leaves, and stems were obtained by micro X-ray fluorescence spectroscopy (μXRF). The detailed analysis of XRF maps was done based on Image-Pro PLUS (Media Cybernetics) software. Cr was accumulated either in trichomes or vascular bundles in respect to the element speciation and the plant organ. The concentration of Cr significantly increased in the following order: Cr(VI) mature leaves < Cr(VI) young leaves = Cr(VI) stems < Cr(III) young leaves ≤ Cr(III) mature leaves ≤ Cr(III) stems. The observed differences in distribution and accumulation of Cr were correlated with the different reduction potential of Cr(VI) by particular plant organs. The reduction of Cr(VI) is considered the main detoxification mechanism of the highly toxic Cr(VI) form. The unique L-band electron resonance spectrometer (L-band EPR) was applied to follow the reduction of Cr(VI) to Cr(III) in the studied material.

“…Simulated studies using Cr(VI) as the spiking agent to investigate different crop reactions and growth have been reported by several authors [15,33,34]. Cr is considered strongly toxic because Cr(III) compounds in the soil are more or less insoluble and their ions are tightly bound to humus and clay particles while Cr(VI) is very soluble and easily passes through the plant cells into vacuoles where they combine with cations and form stable compounds which either accelerate or retard plants growth [34]. Amarantha dubuis Thell and Spinacia oleracea germinated in low concentration only while Cicer arietinum, Phaseoulus vulgaris and Vigna angularis germinated in both low and high concentration of Cr(VI).…”

“…It may be possible to state here that seed coats of different plants' impermeability and embryos' selectivity could have affected the tolerance The current study observed a significant variation in the germination and growth of edible vegetable seeds in Cr polluted soils (Figure 3c). Simulated studies using Cr(VI) as the spiking agent to investigate different crop reactions and growth have been reported by several authors [15,33,34]. Cr is considered strongly toxic because Cr(III) compounds in the soil are more or less insoluble and their ions are tightly bound to humus and clay particles while Cr(VI) is very soluble and easily passes through the plant cells into vacuoles where they combine with cations and form stable compounds which either accelerate or retard plants growth [34].…”

This study reports on the assessment of the growth potential of five edible vegetables, which were grown in Cr(VI) spiked soils. The vegetable plants that were used in this study were Vigna angularis, Cicer arietinum, Spinacia oleracea, Amaranthus dubius Thell and Phaseolus vulgaris. Dried ground samples from roots, stems and leaves were analysed for various oxidation states of Cr. The daily intake of chromium, hazard quotient (HQ) and hazard index (HI) methods were employed to assess the potential human health risks posed by these Cr oxidation states through vegetable consumption. The results showed that Vigna angularis was the only vegetable that germinated in highly concentrated Cr(VI) in the simulated soil (456 mg/kg). The highest total chromium (ChT) bioaccumulated in the roots was found in Phaseolus vulgaris at 0.8. The highest ChT translocation factor in the stem was that of Cicer arietinum and Vigna angularis at 0.30. The same plants translocated the highest ChT to the leaf at 0.7. A child or an adult consuming such contaminated Cicer arietinum vegetables were likely to take in between 508 and 785 mg/day of ChT, which are above the World Health Organisation guidelines of 220 and 340 mg/day, respectively. The highest HQ was found in Cicer arietinum at 8.7 and 13.4 for adults and children, respectively. The same species of plants also had high HI at 17.4 and 27.2 for adults and children, respectively. This indicated that consumers of the edible vegetables grown in Cr(VI) rich soils may be exposed to health risks, and the children were more likely to be vulnerable to these adverse effects than the adults.

“…The Cr transported to the aerial parts or retained at the roots might have affected the physiological processes of plants growth as it contributed to their various reduction in height as shown in Figure 2. [28,14] Simulated studies using Cr (VI) as the spiking agent to investigate different crops reactions have been reported by [29,30,31]. Cr is considered strongly toxic because Cr (III) compounds in the soil are more or less insoluble and their ions are tightly bound to humus and clay particles while Cr (VI) is very soluble and easily pass through the plant cells into vacuoles where they combine with cations and form stable compounds which either accelerate or retard plants growth [32].…”

This study reports on the assessment of the growth potential of five edible vegetables which were grown in Cr (VI) spiked soils. The vegetable plants that were used in this study were Vigna angularis, Cicer arietinum, Spinacia oleracea, Amaranthus dubius Thell and Phaseolus vulgaris. Dried ground samples from roots, stems and leaves were analysed for various oxidation states of Cr. The daily intake of chromium (DIC), hazard quotient (HQ) and hazard index (HI) methods were employed to assess the potential human health risks posed by these Cr oxidation states through vegetable consumption. The results showed that Vigna angularis was the only vegetable that germinated in highly concentrated Cr (VI) in the simulated soil (456 mg/kg). The highest bioaccumulation factor of CrT in the roots was found in Cicer arietinum at 3.5 ± 0.51 mg/kg DW. The highest translocation factor in stem was that of Cicer arietinum and Vigna angularis at 1.0 ± 0.00, while Cicer arietinum and Spinacia oleracea translocated highest Cr to the leaf at 2.1 ± 0.21. A child or an adult consuming such contaminated Cicer arietinum were likely to take in between 508 -785 mg/kg/day of total Cr which were above the World Health Organisation guidelines of 220 and 340 mg/kg/day, respectively. The highest HQ was found in Cicer arietinum at 8.7 and 13.4 for adults and children, respectively. The same species of plants had also high HI at 17.4 and 27.2 for adults and children respectively. This indicated that consumers of the edible vegetables grown in Cr (VI) rich soil may be exposed to health risks and the children were more likely to be vulnerable to these adverse effects than the adult.
