“…Similar depressing effects at the presence of Ni have been reported for radishes (Simon et al 2000), fenugreek (Parida et al 2003), broad bean (Srivastava et al 2005), wheat (Ouzounidou et al 2006) and barley, and tomato (Rooney et al 2007). Some other reports are also available at the presence of Cd for marigold, chrysanthemum and gladiolus (Lal et al 2008), Brassica napus cocropped with B. parachinensis or Zea mays (Selvam and Wong 2009), radish (Asadi Kapourchal et al 2009), wheat (Jafarnejadi et al 2011), and tobacco (Maaroufi Dguimi et al 2009).

Soil contamination by heavy metals, due to human activities, is not often limited to a single contaminant. The objective of this study was to develop a simple model for phytoextracting separate and combined Ni and Cd from contaminated soils. The study was further aimed to study phytoextraction potential of ornamental kale and land cress grown in soils contaminated with separate and combined Ni and Cd metals. The results indicated that elevated Ni and Cd concentrations in soil inhibit growth of both ornamental kale and land cress plants. In Ni + Cd treatments, growth and development of both plants were more affected than in either Ni or Cd treatments. Further, in Ni + Cd treatments, Ni concentration in tissues of both plants was increased by increasing soil Ni concentration under various Cd concentrations. At constant Ni concentration, addition of Cd did not appreciably changed Ni content of plant tissues. Land cress demonstrated higher tolerance to soil contamination by Ni and Cd compared to ornamental kale. It also demonstrated higher phytoextraction potential for soil Cd than ornamental kale. Enhanced bioavailability of Ni and Cd ions, due to competitive adsorption and desorption reactions, had no reasonable effect on metal ion accumulation in plant tissues. This indicates that at relatively high soil contamination, metal ion adsorption is no longer a limiting factor for phytoremediation. The newly proposed model, which assumes that metal uptake rate inversely depends on total soil metal ion concentration, reasonably well predicted the cleanup time of Ni, Cd, and Ni at the presence of Cd from the contaminated soils. The model also predicts that phytoremediation process takes much longer time when soil is contaminated by multi-metal ions.

“…Soil moisture was maintained at field capacity under glasshouse conditions. The soil volume was not a limiting factor for the radish growth (Cai et al , 2008; Kapourchal et al , 2009). When plants were fully developed (at 40 days) they were harvested and divided into shoot and roots.…”

The context of this study is the pollution of soils and water by a persistent organo‐chlorinated insecticide, chlordecone, in a tropical environment. The application of chlordecone to control the banana black weevil has led to continuing diffuse pollution of soils, and to its being a source of contamination for cultivated plants, as well as for terrestrial and marine ecosystems. Chlordecone is toxic and stable and is considered to be a persistent organic pesticide. Consequently, the amounts of chlordecone that could migrate through the environment and contaminate agricultural products need to be controlled. We measured the impact of two composts (5% weight) on chlordecone sequestration in andosols. To this end, we first characterized the transfer of chlordecone from soil to water, and then its transfer from soil to plants. After 3 months of maturation, soil‐water and soil‐plant transfers were reduced by a factor of from 3 to 10. We also showed that adding compost to contaminated soils increases chlordecone sequestration because it leads to changes in soil microstructure in the form of pore collapse and closure of the fractal structure of the allophane content.

“…Moreover, Sani et al (2011) showed that vegetable species may considerably differ in their ability of taking up heavy metals and noticed that the highest concentrations were observed in lettuce (see also Nali et al, 2009). Literature references show that Pb accumulation in radish plant is very strongly related to concentration levels in soil, which fully justifies the use of this species to remediate Pb‐polluted topsoils ( Kapourchal et al, 2009). Akinci et al (2010) report that tomato exposed to increasing concentrations of Pb responded with an increased accumulation of this metal in plant organs, reaching higher concentrations in roots than in leaves.…”

Lead (Pb) and other heavy metals represent a great source of concern in agriculture because they may disperse from polluted sources and accumulate in crop organs. This research study was performed with three edible crops and one pasture species (lettuce: Lactuca sativa L. cv. Romana; radish: Raphanus sativus L. var. radicicola; tomato: Lycopersicon lycopersicum L. Karst.; Italian ryegrass: Lolium multiflorum Lam). It was aimed at (1) assessing how species affect Pb distribution among plant organs, (2) determining the extent to which Pb is localized in edible organs, and (3) ascertaining whether it could be possible to distinguish which compounds are responsible for the transport of Pb from one plant organ to another and which compounds are responsible for the accumulation of this metal inside each plant organ. The experiment was conducted in the greenhouse. Plants were grown in plastic pots using a Pb-spiked sandy soil as substrate. Total Pb concentrations in different plant organs and in soil were determined. Within plants, the maximum accumulation of Pb was found in roots while the remaining part of Pb was mainly located in leaves. Pb L-III edge XANES (X-ray Absorption Near Edge Spectroscopy) was applied to identify the principal Pb carrier molecules in the different plant organs. The data suggest that in roots Pb immobilization is mainly due to the complexing ability of histidine, which binds the metal and, to a lesser extent, to precipitation of Pb as carbonate. The transport to the upper plant organs is mainly attributed to Pb complexes with organic acids. In stems and leaves, Pb bonding is mainly carboxylic and amino acid-like, thus confirming the role of these substances in promoting Pb mobility. Thio amino acidic (glutathione and cysteine-like) Pb complexes, which in this study were only found in stems, can also be held responsible for Pb long-distance transport from roots to shoots
