“…In our study, metal concentration in the shoots was in the order Zn [ Pb [ Ni, whereas the metal concentration in the roots was in the order Pb [ Zn [ Ni. Similar results were obtained by Meers et al (2005) who noted that Helianthus annuus and Z. mays showed more uptake of than Ni. This could be due to the fact that Pb uptake does not require any energetic expense, and it was deposited in large amounts in the roots (Wierzbicka et al 2007).…”

“…Root growth decreased progressively with increasing concentration of Pb in solutions. Meers et al (2005) reported that shoot selectivity of H. annuus was in the order of Zn [ Cu [ Ni [ Cd = Pb, while in Indian mustard, shoot selectivity was in the order of Zn [ Cd [ Ni [ Cu [ Pb (Do Nascimento et al 2006). Jadia and Fulekar (2008) reported that plant growth was adversely affected by heavy metals at higher concentration (40 and 50 mg kg -1 ).…”

Metals are very common contaminants in the soil. High-yielding biomass crops offer good potential for the phytoremediation of soils contaminated with heavy metals. Biomass fuel crops grown on contaminated land have several advantages as site remediation combined with bioenergy production. In this context, two energy crops, Sorghum bicolor and Carthamus tinctorius, were grown hydroponically to assess their potential use in phytoremediation of nickel (Ni), lead (Pb) and zinc (Zn) and biomass production. The experiment was carried out in a growth chamber using half-strength Hoagland's solution spiked separately with five concentrations for Ni, Pb and Zn (between 5 and 100 mg L -1 ). Shoot and root biomass were determined and analyzed for their metals contents. Results showed that the tested plants were able to uptake Ni, Pb and Zn. Furthermore, roots accumulated more metals than shoots. Ni seems to be more toxic than Zn and Pb. In fact, both species were unable to grow at Ni concentration above 10 mg L -1 . Metal toxicity ranked as follows: Ni [ Zn [ Pb. High toxicity symptoms and biomass reduction were observed at concentrations of Pb and Zn above 25 mg L -1 for both species. S. bicolor was more efficient than C. tinctorius in metal uptake due to the high biomass production and the relatively high shoot concentration of metal. S. bicolor could be successfully used in phytoremediation applications in marginal soils with moderately heavy metal contamination. However, results obtained through the hydroponic experiment need to be confirmed by field experiments.

“…S. vulgaris, exceptional in this way was used for comparison in the present study since it is known to hyperaccumulate heavy metals (Broadley et al 2007). Unfortunately its use in phytoextraction, similarly to nonmycorrhizal Brassicaceae plants, is limited due to the low biomass production (Meers et al 2005;Liang et al 2009). On the basis of data shown in the present study, there are several other plant species that can compete with Silene in metal uptake for phytoextraction purposes by simply having much higher yield.…”

Metal uptake by xerothermic plants introduced into Zn-Pb industrial wastes

et al. 2010

The dusty surfaces of post-flotation wastes contain high concentrations of toxic compounds and spread widely if appropriate vegetation is not introduced. It has been previously established that effective restoration of such waste areas are best met by xerothermic, mycorrhiza-assisted plants (Turnau et al. Plant and Soil 305:267-280, 2008). The aim of the current study was to improve phytostabilisation practices by gaining insight into the elements uptake in plants after their change of habitat. Total Reflection X-ray Fluorescence (TXRF) was employed to evaluate element concentration in the leaves of 23 plant species growing in the wild and on Zn-Pb waste. Higher levels of heavy metals (Zn, Y, As, Pb, Cu) in plants from tailings were usually accompanied by increased Ca concentration, suggesting a possible role of this element in detoxification mechanisms. Also, when compared to grassland specimens, plants from the tailings, exhibited potassium-deficiency. Thus, K-supplementation of the waste substrata should be considered to improve plant growth. Among all the introduced plants, three grass species (Melica transsilvanica, Bromus inermis, Elymus hispidus) and one legume (Anthylis vulneraria) were the most suitable for phytostabilisation. Heavy metal-accumulating properties of Verbascum thapsus need further investigation.

“…Plants developed efficient physiological and biochemical mechanisms of the uptake, translocation and accumulation of microelements, even at their low concentrations. The same mechanisms are also used to absorb toxic substances with chemical properties similar to microelements (Panwar et al 2002;Subhashini and Swamy 2013;Meers et al 2005). Plant species and varieties are characterized by a greatly diversified ability for heavy metals accumulation (Ogunkunle et al 2014;Yang et al 1996).…”

Nickel bioaccumulation by the chosen plant species

et al. 2016

View full text Add to dashboard Cite

The investigations aimed at the evaluation of nickel bioaccumulation ability of plants from various families (Poaceae-maize, Fabaceae-field bean and Asteraceae-lettuce). The research was conducted under hydroponic conditions. The experimental design comprised ten objects differing with nickel concentrations in the solution (ranging from 0.0 to 10.0 mg Ni dm -3 of the nutrient solution). The parameters, assumed as the basis on which nickel bioretention by selected plant species was determined were: the yield, nickel content in various plant parts, uptake and utilization of this element by the plant, tolerance index (TI) and translocation factor (TF), the metal concentrations in the aboveground parts index (CI) and bioacummulation factor (BAF). On the basis of the obtained results it was found that, due to low tolerance of nickel, maize could be used as the indicator plant for the environment quality assessment.
