“…Kabata-Pendias and Pendias ( 1992 ) reported a higher increase of Zr content in nodules and roots of legumes than in aerial parts. Wang et al ( 2000 ) found the same result for soybean plants that were cultivated in a radio contaminated soil, even for a longer growing period (up to 60 days after sowing). found that Zr in Oryza sativa was concentrated in the roots and lower part of the stem.…”

Like Pb, generally more that 90% or more of absorbed Zr is accumulated in plant roots (Kabata-Pendias and Pendias 1992 ; Wang et al 2000 ;Klechkovsky and Gulyakin 1958 ;Ferrand et al 2006 ;Yan et al 2010 ;Gupta et al 2010 ;Jiang and Liu 2010 ) .…”

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.

“…Overall, despite differences between laboratory and field, and between species, reported TFs for 99 Tc are high. They can be as high as for any other radionuclide that is a potential contaminant of terrestrial systems (Sheppard and Evenden, 1997;Yanagisawa and Muramatsu, 1997;Wang et al, 2000).…”
