“…Our previous results indicated that the content of Cd, Cu, and Pb increased with increasing levels in the root zone. In this regard, Mleczek et al (2013) found a general increase in Cu accumulation in S. viminalis organs with increased Cu concentrations in the medium. Additionally, S. polaris organs treated with Cd have shown different concentrations between plant parts (Krajcarova et al, 2016).…”

“…Moreover, Dos Santos Utmazian et al (2007) revealed that willow growth and phytoextraction efficiency were significantly dependent on the planted species, and that there were differences in plant biomass, metal tolerance, and metal phytoextraction of willow clones. In addition, BCF values of different organs (leaf, bark, shoots, and roots) of S. viminalis in Cu concentrations of different Ca/Mg ratios were estimated as weak in most cases and as moderate in some cases, particularly in roots (Mleczek et al, 2013).…”

Phytoremediation is an environmentally friendly and effective method of reducing contaminating ions to very low levels. In this study, the effects of different concentrations of cadmium (Cd), copper (Cu), and lead (Pb) on vegetative growth and the chemical and biochemical compositions of Salix mucronata as well as the potential for phytoextraction of these metals by plant organs were investigated. S. mucronata had the highest survival percentage (100%) in the presence of CdCl2, CuCl2, and Pb acetate up to 80, 200, and 850 mg·kg−1 in soil, respectively. A negative influence of these metals on vegetative and chemical parameters was observed relative to the control plants. The potential role of antioxidant enzymes in protecting plants from oxidative injury was examined by analyzing the antioxidant enzyme activities of plants grown in contaminated and control soils. Enzymatic activities and electrolyte leakage were higher in the plants grown in soil with increasing heavy metals than in the control plants. The bioconcentrating efficiency of Cd, Cu, and Pb in plant organs was estimated to be medium [bioconcentration factor (BCF) of 1–0.1]; an exception was the BCF of Cu in the roots, which was estimated to be intensive (BCF < 1). Concentrations of 60 mg·kg−1 CdCl2, 50 mg·kg−1 CuCl2, and 650 mg·kg−1 Pb acetate caused significantly higher translocation compared with other levels of each pollutant. The biomass tolerance index was less than 1. Additionally, S. mucronata accumulated Cd, Cu, and Pb in the following order: roots > stems > leaves. Therefore, the risk of contamination through leaf fall can be minimized. Therefore, S. mucronata could be a good candidate for phytoremediation of Cd-, Cu-, and Pb-contaminated soil.

“…The results were compared with the certified reference material NCS ZC 73030 from the China National Analysis Center for Iron & Steel 2014 and with reference solutions by Fluka assigned the symbols: Pb 16595, Cd 51994, Cr 02733, Ni 42242, Mn 63534, Zn 18827, Cu 38996, Fe 16596, and Co 119785.0100. Moreover, the following coefficients were calculated for cobalt determined in oat grain, straw, and roots: bioconcentration coefficient from the formula: (BCF) = C plant organ /C soil , translocation coefficient (TF) = C aerial parts /C roots , and transfer coefficient (TFr) = C plant /C soil , where C stands for cobalt content expressed in mg kg −1 (Ali et al 2013 ; Mleczek et al 2013 ). Moreover, tolerance index Ti was computed from the formula: Ti = biomass yield from a cobalt-polluted object / biomass yield from the control object.…”

The aim of the study was to determine the effectiveness of soil application of manure, clay, charcoal, zeolite, and calcium oxide in remediation of soil polluted with cobalt (0, 20, 40, 80, 160, 320 mg Co kg −1 of soil). The following were determined: weight of harvested plants as well as the content of cobalt in grain, straw, and roots of oat. In addition, tolerance index (Ti), cobalt bioconcentration (BCF), translocation (TF), and transfer (TFr) coefficients were derived. In the series without amendments, the increasing doses of cobalt had a significant effect by decreasing the yields of oat grain and straw and the mass of its roots. Also, lower tolerance index values were noted in the objects polluted with cobalt, especially with its highest dose. The application of manure had the strongest effect on increasing the mass of particular organs of the test plant, while the application of charcoal led to a significant decrease in this respect. The application of all substances to the soil, and especially manure and calcium oxide, resulted in higher tolerance index Ti values. The growing contamination of soil with cobalt caused a significant increase in the content of this element in oat and in the values of the translocation coefficient, in contrast to the effects noted with respect to the bioconcentration and transfer coefficients. All the substances applied to soil reduced the content of cobalt and its bioconcentration in oat straw, in opposition to grain and roots, limited its translocation, but elevated the transfer of this element from soil to plants. Soil contamination with cobalt promoted the accumulation of lead and copper in grain, cadmium, lead, nickel, zinc, manganese, and iron in straw, as well as cadmium, nickel, zinc, and manganese in oat roots. As the cobalt dose increased, the content of other trace elements in oat organs either decreased or did not show any unambiguous changes. Of all the tested substances, the strongest influence on the content of trace elements was produced by calcium oxide in straw and roots and by zeolite in roots, whereas the weakest effect was generated by manure in oat grain. Oat is not the best plant for phytoremediation of soils contaminated with cobalt.

One-year-old cuttings of basket willow (Salix purpurea 9 viminalis) were cultivated hydroponically under increasing Cu concentrations (0, 1, 2 and 3 mM) and at four Ca/Mg ratios (4:1, 1:10, 20:1 and 1:1 / 4 ). After 14 days, rhizosphere and leaf samples were analysed. Salix plants were able to release relatively high amounts of low molecular weight organic acids (LMWOAs) in a short period of time. The total amount of LMWOAs increased with increasing Cu concentrations. Oxalic and acetic acids were dominant, and act as complexing agents for Cu ions, and therefore, organic exudates should be taken into account in phytoextraction of polluted areas. The Ca/Mg ratio of the medium significantly influenced not only concentration, but also the composition of LMWOAs. Phenolics content in leaves increased with the excess of Ca and Mg and with Cu level in the medium for all Ca/Mg ratios. The accumulation of glucose, fructose and sucrose in leaves was observed for deficiency and excess of Ca and/or Mg and Cu treatment at all Ca/Mg ratios. Excess calcium (Ca/Mg = 20:1) led to strong induction of salicylic acid biosynthesis, probably resulting from enhanced oxidative stress.
