“…Only a small portion could be transported to the shoots, indicating their limited mobility once inside the plant. This is consistent with previous reports (Deng et al 2004;Fitzgerald et al 2003), whereas the exclusion of metals from aboveground tissues has been suggested as a metal tolerance strategy for wetland plant species (Taylor and Crowder 1983). The results also showed that metal accumulation by wetland plants differed among species.…”

Background and aims Measuring specific ion fluxes from different regions of the root under practical physiological conditions is crucial for understanding metal uptake mechanisms by plants. Methods We developed and tested a neutral carrierbased liquid-membrane Pb 2+ and Cu 2+ ion selective microelectrode (ISME) to investigate ion-transport processes along the roots of three common wetland plant species. Results The Pb 2+ and Cu 2+ ISME exhibited a Nernstian response with Pb 2+ and Cu 2+ activities as low as 1.0 nM and 1.0 μM in deionized water and simulated soil solution, respectively. Phragmites australis had a region of Cu 2+ release for approximately the first 200 μm, while it exhibited Pb 2+ and Cd 2+ outward net flux up to the first 500 μm. Although in older sections of the root of Phragmites australis there were areas of influx of Cu 2+ , Pb 2+ and Cd 2+ , the overall influx was much smaller than that of Typha latifolia or Canna indica. Such a reduced uptake and/or an increased efflux of metal ions across the root-cell plasma-membrane might explain the higher resistance of Phragmites australis to metals, at least in part. Conclusions The Pb 2+ and Cu 2+ ISMEs are shown to permit detailed investigation of heavy-metal ion transport in plant roots, especially for plants used for phytoremediation.

“…2a, Pb, As, Ni, and Co accumulated by desert broom was retained in the roots and TF values less than 1 demonstrates the limited mobility of Pb, As, Ni, and Co in desert broom. Each plant species might have a unique mechanism against any metal; however, similar results were found in other research for Pb (Fitzgerald et al, 2003), As (Geng et al, 2006), Ni (Nkoane et al, 2005), and Co (Page et al, 2006). The elevated metal concentrations in roots and low translocation to the aboveground tissues in some investigated species might also suggest that they are capable of rather well-balanced uptake and translocation of metals under heavily metal-polluted conditions (Nkoane et al, 2005, Deng et al, 2004).…”

This research was conducted out at a copper mine tailings reclamation project (CMTRP ) located in the Globe-Miami mining district near Claypool, AZ, USA. Desert broom (Baccharis sarothroides) is a very environmentally friendly and available plant that might have phytoremediation potential, grows at the CMTRP. Therefore, in this research metal concentrations both in the tailings and plants (elemental ratio from soil to plant) were investigated. The metal concentrations in the soil cover and tailings were determined using ICP-OES. Based on the concentration, the elements were classified as high level elements

“…Populations of Suaeda maritima from the inland saline areas preferred accumulation of metals in the above-ground parts (stems and leaves), while populations of the same species from the maritime saline areas preferred accumulation in the root. The variable results with Suaeda maritima may have been due to differential water logging within sites that affected metal uptake [27,28].…”

“…Some previous studies show poor correlations between metal uptake by plants and metal concentration in soils [27,29]. Gregory et al [30] indicated that concentrations of Cu, Ni, Fe, and Mn in Typha latifolia L. root tissues correlated with concentrations in wetland sediments.…”

Heavy metal content in halophytic plants from inland and maritime saline areas

We investigated the concentration of Aluminium (Al), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni) and Zinc (Zn) in the root and aboveground organs of four halophyte species (Salicornia europaea, Suaeda maritima, Salsola soda and Halimione portulacoides), as well as in the soil from maritime and inland saline areas. The aim of our research was to evaluate the capability of some halophyte species to absorb different heavy metals and to detect differentiation of heavy metal accumulation within populations from inland and maritime saline areas. Generally, the plant roots had significantly higher concentrations of metals when compared to stems and leaves. Zinc was the only metal with concentrations significantly higher in the leaves than in the root and stem. Populations from maritime saline areas had higher trace root and stem metal concentrations than populations from inland saline areas. Excepting zinc, populations from inland saline areas had higher heavy metal concentrations in the leaves. The factors that affected metal accumulation by halophytes included the percentage of salt in the soil. We also discuss the potential use of these halophytes in phytoremediation.
