“…Initial parameters (fresh weight and length) were measured, air-dried, oven-dried at 75 °C for 48 hours, cooled, weighed, and milled accordingly with ZM1000, Retsch, Germany. Sample weight of 100 mg each was microwave digested with Ethos plus 2, MLS as recommended by Krachler et al, [23] and Okoroafor et al, [24]. The digestion was aided by 3 mL nitric acid and 0.1 mL hydrofluoric acid.…”

“…For the total elemental contents in soils, 0.5 g of pulverised sample, and 2 g of even portions of Na 2 CO 3 and K 2 CO 3 were homogenised for the melting digestion technique as employed by Okoroafor et al, [24]. Thus, heated the mixture at 900 degrees for half an hour in a muffle furnace, cooled and liquified with 50 mL of a solution of 2 mol/L nitric acid and 0.5 mol/L citric acid.…”

“…Despite this, the geo-chemical behaviour and interaction of elements in soil can strongly influence how much PTEs can be mobilised for absorption, translocation and/ or storage by plants. Soil contaminants mostly associate with organic matter in soils and/ or as carbonates [24,26]. This makes the bioavailability of toxic elements a single but crucial factor to determine the success of any phytoremediation [24].…”

Phytoremediation approaches have increasingly been applied in environmental remediation projects. In this study, the potentials of Manihot esculenta (M. esculenta), Vigna unguiculata (V. unguiculata) and J. curcas curcas (J. curcas) in remediating multi-contaminated mine spoils was evaluated. The target potentially toxic elements (PTEs) are Cd, As, Zn, Pb, and Hg. The test plants were grown and monitored under growth stress conditions for 270 days. Using inductively Coupled Plasma- Mass Spectrometry and EPA method 200.8, the total elemental contents in the shoot and root parts of the plants were determined. Significant differences (p< 0.01) were observed in the uptake performance of the test plants. For example, M. esculenta and J. curcas, bioaccumulated 50- 80 % of the various baseline PTE contents in their root parts at 270 days after planting. In contrast, < 27 % of PTEs were found in the root parts of V. unguiculata, except Zn at 70 %. Growth stressors and soil PTEs were factors that reduced biomass production in respective plants by 25 %. Cummulatively, the performance order M. esculenta> J. curcas> V. unguiculata was observed for multi-contaminant removal in soils. Techniques for enhancing the easy cultivation of the test plants are recommended to enhance their applicabilities in phytoremediation projects.

“…Furthermore, current studies on REEs in plants focus on a small number of species, particularly on REE accumulating plants like Phytolacca americana and Dicranopteris linearis 13 , 16 – 20 . Accumulating plants are an excellent way to study elemental uptake pathways, but it is important to diversify the number of plant species studied, since elemental uptake pathways are species dependent and may even vary from one population of the same species to another 21 .…”

Yttrium (Y) has gained importance in high tech applications and, together with the other rare earth elements (REEs), is also considered to be an emerging environmental pollutant. The alpine plant Saxifraga paniculata was previously shown to display high metal tolerance and an intriguing REE accumulation potential. In this study, we analysed soil grown commercial and wild specimens of Saxifraga paniculata to assess Y accumulation and shed light on the uptake pathway. Laser ablation inductively coupled plasma mass spectrometry and synchrotron-based micro X-ray fluorescence spectroscopy was used to localise Y within the plant tissues and identify colocalized elements. Y was distributed similarly in commercial and wild specimens. Within the roots, Y was mostly located in the epidermis region. Translocation was low, but wild individuals accumulated significantly more Y than commercial ones. In plants of both origins, we observed consistent colocalization of Al, Fe, Y and Ce in all plant parts except for the hydathodes. This indicates a shared pathway during translocation and could explained by the formation of a stable organic complex with citrate, for example. Our study provides important insights into the uptake pathway of Y in S. paniculata, which can be generalised to other plants.
