“…In those situations, the selection of suitable plant species with the desired properties should be carefully considered (Murakami and Ae, 2009;Testiati et al, 2013). Studies performed under similar conditions are a useful strategy to compare the uptake characteristics of different species for different trace metals (Chehregani et al, 2009). Furthermore, phytoremediation efficiency can be enhanced through several types of changes such as by increasing oxygen levels in roots through aeration which may facilitate or difficult metal uptake (Zhao et al, 2009) or by improving soil nutrient levels through fertilization in order to promote plant growth and thus trace metal uptake (Erenoglu et al, 2011).…”

“…Willows have not been included in the group of hyperaccumulators of heavy metals, but on the other hand they provide potential bioindicator of pollution (Mleczek et al, 2009). However, metal concentrations in willows depend on species, growth performance, root density, distribution within the soil profile and sampling period (Chehregani, et al, 2009). Moreover, willow has been recently recognized as a good accumulator of heavy metals (Meers et al, 2007).…”

Human activities such as metals mining and milling operations provide one of the most important sources of contamination in the environment. Abandoned mines can be an important source of toxic elements. The threat of heavy metal pollution posed by mine soils generally concerns more than one metal. The aim of this study was to assess total concentration of six potentially toxic metals (Cd, Cr, Cu, Pb, Zn and Fe) in the soil and plant samples of three dominant willow species (Salix purpurea L., Salix caprea L. and Salix eleagnos Scop.) collected from abandoned mixed sulphide mine dumps (Imperina Valley, North-east Italy). Results demonstrate that metal concentrations in soils are in general above the Italian average limits and they are also significantly (except Cr), as compared with controls (p ≤ 0.05), with averages of 2.12 mg Cd kg −1 , 2267 mg Cu kg −1 , 9552 mg Pb kg −1 , 1243 mg Zn kg −1 and 299,973 mg Fe kg −1 . The phytoremediation ability of selected Salix species for heavy metals was estimated. The results have revealed significant differences among willow species (p ≤ 0.05) regardless of the species selected. The transfer factor and bioaccumulation coefficient of selected metals varied among plant species and from different sites. Some of the investigated species have potential for soil stabilization and extraction of heavy metals. The results indicate that there is an increasing need for further research projects mainly focused on the mechanisms whereby such willows are able to survive in contaminated soils.

“…Their accumulation in soils can become dangerous to all kinds of organisms, including plants (Gichner et al, 2006). This accumulation in arable soils is more serious, since these toxic elements can be taken up by plants and transferred to human (Chehregani et al, 2009). In the present experiment, the addition to soil of cocopeat and peatmoss was intentionally designed to prove the hypothesis that application of these materials to substrate would assist plant growth and Cd uptake in two poplars (species with fast growth rate and deep root system) in the same time.…”

A b s t r a c t. To investigate the effect of amended substrates on cadmium uptake by one-year old poplar rooted cuttings a pot culture was carried out. Pots were filled with three substrates. Four treatments of Cd supply including were organized. The results showed that higher biomass productions in substrates A and B compare to substrate C, led to an increase total Cd uptake two times more than that in substrate C, at 150 mg kg -1 concentration. Meanwhile maximum total uptake occurred in substrate B at 100 mg kg -1 concentration. Using synthetic chelators such as ethylenediaminetetraacetic acid in order to achieve high removal rate led to increased environmental impacts while they are not expected when such environmental friendly approaches are applied.K e y w o r d s: soil, cadmium, ethylenediaminetetraacetic acid, phytoextraction, substrate
