“…In the present study, B. napus cultivars tend to accumulate more Cd in their roots, which shows their capability to avoid metalinduced stress (Najeeb et al 2011). Increased Cd concentration inside the plant induces the metal toxicity by replacing some of the essential cations such as Ca 2+ and Fe 3+ (Van Engelen et al 2007). In addition, excess of Cd 2+ in plant cell can inhibit the activities of various organic compounds by making bonds with side groups (McGrath et al 2002).…”

“…Plants exposed to elevated copper levels had previously been reported to show reduced biomass yield, chlorotic symptoms (Yruela 2005), and poor root growth (Lepp 2005). The Cd toxicity observed could be due to replacement of some of the essential cations such as Ca 2+ and Fe 3+ by Cd 2+ ions (Van Engelen et al 2007). Cadmium accumulated in shoots has been attributed to association with phytochelatins and sequestered in the cell wall vacuoles (Salt et al 1995).…”

Amendments and their combined application for enhanced copper, cadmium, lead uptake by Lolium perenne

Chemical amendments can enhance heavy metal phytoextraction by increasing metal bioavailability for plant root uptake and translocation to shoots, and by improving plant growth. This study assessed the effect of various amendments on plant growth and metal uptake over a 30-day period. An aminopolycarboxylic acid (EDDS), amino acid (histidine), organic acid (citric acid), biosurfactant (rhamnolipid), and inorganic ligand (sulfate) were applied as amendments individually or in combination to hydroponically grown ryegrass (Lolium perenne cv. SR4500) in the presence of a metal (Cu, Cd or Pb). EDDS (1 mM) was the most effective amendment (individually and in combinations) for enhancing Cu and Pb uptake to shoot tissue, while histidine was beneficial for increasing both Cu and Cd uptake. Individual treatments of citric acid, rhamnolipid and sulfate moderately enhanced shoot concentrations of Cu and Cd only. The combination of EDDS, rhamnolipid and citric acid resulted in the highest shoot metal levels, but also caused severe phytotoxicity.Translocation to shoot tissue was generally greater for amendments with higher affinity for the metal of interest, and metal mobility appeared to be influenced by speciation. Due to potential toxicity, amendment combinations may be more effective when applied shortly before harvesting.

“…While cadmium shoot concentrations did not vary in time, zinc concentration gradually decreased during the vegetation period (Ghosh and Singh 2005;McGrath et al 2006). Besides hyperaccumulators, there are plant species like Salix viminalis, T. caerulescens (which uptakes up-large portion of Cd and Zn), Brassica juncea (Pb, Cd, Hg), Lolium perenne (Pb), Zea mays (Pb), Helianthus annuus, and other plants (Pb, Cu, Zn), characterized by high content of heavy metals in biomass and good remediation capacity (Quartacci et al 2006;Van-Engelen et al 2007;Koopmans et al 2008;Padmavathiamma and Li 2007;Wang et al 2009). Highest Cd concentrations in the roots of Achillea ageratum, Plantago lanceolata, and Silene vulgaris were 338, 1,150, and 249 mg/kg dry weight (dw), respectively, while those in the leaves were 1,367, 569, and 1,163 mg/kg dw.…”

Contamination of metal ions in soil and water represents more pressing threats to resources as well as human health. The present research was carried out to screen the phytosequester plants growing in industrial waste-and wastewater-affected industrial areas of Okhla, New Delhi, India. Accumulation trend of metal Fe, Zn, Cu, Cr, Pb, Cd, Hg, and As from soil and wastewater by plants were collected for study. Among aquatic plants Hydrilla verticillata, Marsilea quadrifolia, and Ipomea aquatica were found to be highest metals accumulator, Eclipta alba and Sesbania cannabina among terrestrial plant were highest accumulator of metals. Among the algal spp. Spirulina platensis and Phormidium papyraceum were the most efficient in accumulating Cd and Hg. The maximum bioconcentration factor (BCF) was recorded in Hygroryza aristata for the metals (Hg, Cd) in M. quadrifolia (Cd, Cr), in E. alba (Cr, Cu), and in S. platensis (Hg, Pb). However, the translocation factor (TF) of metals was found more in M. quadrifolia followed by I. aquatica than other plants. Among all the plants, H. verticillata showed high TF and low BCF values for toxic metals (Pb, Cr) and was suitable for phytostabilization of these metals. Our study showed that native plant species growing on contaminated sites may have a potential of phytosequestration of these metals.
