“…This finding suggests that heavy metal concentration accumulation in plants is partly completed through the method of initial cutting soaked in metal solutions. The initial cutting is implicated in phytoextraction during early willow growth even without roots (Algreen et al 2014). Cutting absorption is quite low in long-term plant growth.…”

Salix species are widely used as vegetation filters because of their flourishing root system and fast growth rate. However, studies have yet to determine whether the root system functions in vegetable filters with mixed heavy metal (HM) pollution or whether initial cutting participates in the phytoextraction of HMs. This study aims to determine the function of the root system and initial cutting as vegetation filters in the absorption and accumulation of Cd and Cu. Thick (>1 cm in diameter) and fine (<1 cm in diameter) initial cuttings of Salix matsudana were planted in a nutrient solution with single and mixed (Cd + Cu) treatments. The roots of several initial cuttings were removed daily to eradicate rhizofiltration. Results revealed that the existence of the root system altered distribution and interaction of Cd and Cu in plant organs and enhanced tolerance and phytoextraction capacity of plants. The initial cuttings could also absorb and accumulate HMs in the early growth stages of willow without roots. Cu inhibited the plant absorption and accumulation of Cd and promoted Cd transport to shoots. Cd inhibited the Cu absorption of the root system. Our study provided essential data regarding woody species as vegetation filters of HM pollution.

“…The field studies with S. viminalis were conducted by Ali et al (2003), Algreen et al (2014), and Kacalkova et al (2014), but only on soils contaminated with several heavy metals jointly, so it was not possible to assess the impact of the Ni exclusively on the formation of willow biomass.…”

“…Literature data report of numerous places in the world where Ni exceeds the permissible limit. For example, the Ni concentration of the soil was 1600-2150 mg kg −1 at Sudbury smelting area in Canada (Adamo et al 2002;Narendrula et al 2012), 303 mg kg −1 at Plovdiv non-ferrous metal smelter in Bulgaria (Bacon and Dinev 2005), 267 mg kg −1 around the Selebi Phikwe Cu-Ni mine in Botswana (Ngole and Ekosse 2012), 212 mg kg −1 at the former sludge disposal site in Denmark (Algreen et al 2014) and 122 mg kg −1 at the area of a former waste incineration plant in Czech Republic (Kacalkova et al 2014).…”

“…On the other hand, research on the potential of Ni phytoremediation of other species, mainly willow and maize, was mostly carried out in pots, or more often, in hydroponics, which does not reflect field conditions in which these plants actually grow (Antonkiewicz et al 2016;Drzewiecka et al 2012;Kopittke et al 2010;Seregin et al 2003). The only available study on willow and maize conducted under field conditions was on the soils contaminated with several metals jointly, which did not allow to draw conclusions about the Ni exclusively (Algreen et al 2014;Kacalkova et al 2014;Mleczek et al 2009). All in all, there is a lack of research that could be a reliable basis for the assessment of the suitability of mentioned species for the phytoremediation of sites polluted with Ni.…”

The aim of this study was to evaluate the usefulness of Phalaris arundinacea, Salix viminalis and Zea mays to the phytoremediation of the soil contaminated with nickel. A 2-year microplot experiment was carried out with plants growing on Ni-contaminated soil. Microplots (1 m 2 × 1 m deep) were filled with Haplic Luvisols soil. Simulated soil contamination with Ni was introduced in the following doses: 0-no metals, Ni 1 -60, Ni 2 -100 and Ni 3 -240 mg kg −1 . The phytoremediation potential of plants was evaluated using a tolerance index, bioaccumulation factor, and translocation factor. None of the tested plants was a species with high Ni phytoremediation potential. All of them demonstrated a total lack of usefulness for phytoextraction; however, they can be in some way useful for phytostabilization. Z. mays accumulated large amounts of Ni in the roots, which made it useful for phytostabilization, but, at the same time, showed little tolerance to this metal. For this reason, it can be successfully used only on soils medium-contaminated with Ni, where a large yield decrease did not occur. Its biomass may be safely used as cattle feed, as the Ni transfer from roots to shoots was strongly restricted. P. arundinacea and S. viminalis accumulated too little Ni in the roots to be considered as typical phytostabilization plants. However, they may be helpful for phytostabilization due to their high tolerance to Ni. These plants can grow in the soil contaminated with Ni, acting as a protection against soil erosion or the spread of contamination.

“…Thus, Wehrer et al 2014 apply tomography to investigate the complexity of preferential flow and transport at the smaller scale of a lysimeter, while Bloem et al 2014 consider a similar process with the innovative Multi Compartment Sampler MCS. Noninvasive monitoring techniques can, of course, also be extended to measurements using biota, as Algreen et al 2014 show with their work on phytoscreening and extraction of metals by trees, and Schurig et al 2014a for an in situ microcosm approach coupled with direct push technique for groundwater remediation assessment. The feasibility of Direct Push/Cone Penetrometer Technology (DPT/ CPT) as a function of soil type in Europe is described by Fleischer et al 2014.…”
