“…There are also antioxidants of low molecular weight such as proline (PRO), cysteine (Cys), nonprotein thiol (NPT), ascorbic acid (AsA), and glutathione (GSH) that scavenge ROS, thereby prohibiting cell injury and tissue dysfunction ( Lyubenova and Schröder 2011 ;Mou et al 2011 ;Lomonte et al 2010 ;Ali et al 2011 ) .…”

Zirconium (Zr) is a transition metal that has both stable and radioactive isotopes.This metal has gained significant attention as a major pollutant of concern, partly because it has been prominent in the debate concerning the growing anthropogenic pressure on the environment. Its numerous past and present uses have induced significant soil and water pollution. Zr is generally considered to have low mobility in soils. The behavior of Zr particularly depends on the characteristics of the media in which it exists, and even its presence in the biosphere as a contaminate may affect its behavior. In this chapter, we describe the relationship between the behavior of Zrand its speciation in soils, its uptake and accumulation by plants, its translocation and toxicity inside plants, and mechanisms by which plants detoxify it.Zr is abundant and occurs naturally in the earth's crust. Zr emissions to the atmosphere are increasing from anthropogenic activities such as its use in industry and nuclear reactors. Zr forms various complexes with soil components, which reduces its soil mobility and phytoavailabilty. The mobility and phytoavailabilty of Zr in soil depend on its speciation and the physicochemical properties of soil that include soil pH, texture, and organic contents. Despite having low soil mobility and phytoavailability,amounts of Zr are absorbed by plants, mainly through the root system and can thereby enter the food chain.After plant uptake, Zr mainly accumulates in root cells. Zr does not have any known essential function in plant or animal metabolism. Although little published data are available, we conclude that the phytotoxicity of Zr is generally low.Notwithstanding, Zr can significantly reduce plant growth and can affect plantenzyme activity. When exposed to Zr-induced toxicity, plants possess numerous defense mechanisms to cope with the toxicity. Such strategies include Zr sequestration in plant roots and activation of various antioxidants. Because Zr may have impact on the biosphere, we believe it deserves to be evaluated in supplementary studies that will enhance the understanding of its behavior in soil-plant systems.

“…2) is of interest as heavy metals mainly accumulate in roots or underground storage organs (Msuya et al, 2000;Anderson et al, 2005;Esteban et al, 2008;Shiyab et al, 2008;Lomonte et al, 2010a). In terms of biomass allocation to roots, there was no significant difference among the Indian mustard plants grown in the different substrates, ranging from 6-13% only (Fig.…”

“…Other studies on the phytoremediation of mercury in contaminated soils have been reported using different plant species such as Atriplex canescens (saltbush ) (Patra and Sharma, 2000), Rumex induratus and Marrubium vulgare (common horehound) (MorenoJiménez et al, 2006), white lupin (Ximenez-Embun et al, 2001), Tritcum aestivum (wheat) (Cavallini et al, 1999), Pisum sativum (pea) (Beauford et al, 1977;Godbold and Huttermann, 1986), Sorghum bicolor (sorghum) (Patra and Sharma, 2000), Chrysopogon zizanioides (vetiver grass) (Wong, 2003), Azolla caroliniana (an aquatic fern) (Bennicelli et al, 2004), and Oryza sativa (rice) (Du et al, 2005). Few studies however, have been carried out on biosolids phytoremediation and Hg was found mainly in the roots of the nine plant species tested with very low translocation to the shoot (Lomonte et al, 2010a). In order to find the best plant species for future phytoextraction or phytomining studies, several candidate plant species known for Hg and/or Au uptake have been identified and they include Indian mustard, white lupin, sugar beet, carrot, cassava, and potato.…”

“…The tap roots of Indian mustard are strong and easy to harvest (Rakow, 2004), making it an ideal plant for root phytoextraction. Hg uptake/phytoextraction or Au uptake/phytoextraction have already been studied using this plant (Anderson et al, 2005;Shiyab et al, 2008;Lomonte et al, 2010a), but not both elements together. White lupin is also known to take up Hg (Esteban et al, 2008).…”

Each plant species exhibited differential responses in terms of germination, seedling quality, leaf area, specific leaf area, root and shoot biomass, and percentage dry matter partitioning to the roots. Both the Indian mustard and carrot grew successfully in the biosolidsmine tailings substrate combinations while white lupin, sugar beet, cassava, and potato failed to grow in most of the substrate combinations. The most suitable biosolids-mine tailings combination was determined to be 75% biosolids -25% mine tailings, wherein most of the abovementioned growth parameters did not differ significantly from those of the plants grown in the control potting mix.

“…For the efficient application of phytoextraction, plants must accumulate a high amount of mercury in the aboveground parts and produce large quantities of biomass. However, as a defense mechanism, mercury is mostly stored in roots [7][8][9][10][11], hindering remediation through phytoextraction. Moreover, mercury phytoextraction using hyperaccumulator plants is currently not possible because no plants have been found to hyperaccumulate this metal.…”
