“…Hutchinson et al (1975) stated that poor correlations existed between both Cu and Ni concentrations in sediment and in N. variegatum roots. Previous studies have mostly shown only poor correlations between the metal uptake of wetland plants and the sediment concentrations (Dunbabin and Bowmer, 1992;Greger, 1999;Deng et al, 2004). Because of this, concentration factor (CF) of metals on N. lutea, was calculated as metal concentration (mg g À 1 ) in plant partsymetal concentration (mg L À 1 ) in surrounding water (Choo et al, 2006).…”

Heavy metal bioaccumulation and translocation properties of aquatic plants are interesting because of their potential use in phytoextraction. However, there is not enough knowledge about the seasonal changes of the metal distribution properties of aquatic plants. Our study focused on seasonal variation of some heavy metals in relation to their bioaccumulation and translocation in Nuphar lutea, a floating leaved, widespread plant that is important to wildlife. In this study, N. lutea, corresponding sediment and water samples were collected at different seasons from Lake Abant (Turkey) and analysed for their heavy metal content (Pb, Cr, Cu, Mn, Ni, Zn and Cd). Accumulation and translocation of heavy metal ratios were calculated seasonally. It was found that Cr and Zn were actively transported from sediment to the root, where they accumulated especially in summer; it was also shown that Cu, Mn and Zn were not only taken up from the sediment but also from the surrounding water. The investigations suggested that translocation ratios for leafyroot of Pb, Cr, Mn and Zn reached their highest levels in spring. It was found that the bioaccumulation and translocation of heavy metals at different parts of N. lutea changes with respect to season and the type of heavy metal.

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

et al. 2012

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.

“…Natural and artificially-planted aquatic treatment systems making use of cattails have been used to perform satisfactory sewage treatment. Recently, wetlands have also been used to treat metal-contaminated effluent (Erten et al, 1988;Wildeman, Laudon & Howard, 1988;Miedecke, 1989;Dunbabin & Bowmer, 1992;Ye et al, 1992a). It is uncertain, however, whether the distribution of T. latifolia is related to its capacity to evolve metal tolerance when growing on metal-contaminated soils, or whether it has an innate metal tolerance throughout its range.…”

Zinc, lead and cadmium tolerance, uptake and accumulation by Typha latifolia

et al. 1997

SUMMARYZinc, lead and cadmium tolerance in four populations of Typha latifolia raised from seed collected from metalcontaminated and uncontaminated sites were investigated. Metal concentrations in natural plant populations showed that Zn, Pb and Cd in the leaves were maintained at low levels (Zn: 22-122, Pb: 4-7-40 and Cd: 0-2-0-8 //g g~^ d. wt), although concentrations of these metals in the associated soil-sediments (total concentrations of Zn: 86-3009, Pb: 26-18894 and Cd: l-4-26//gg-i d. wt) and in the roots (Zn: 46-946, Pb: 25-3628 and Cd: 10-17//g g"^ d. wt) varied widely. Some differences were found between metal-contaminated and uncontaminated populations in terms of metal uptake under controlled conditions. Seedlings from metal-contaminated populations accumulated considerably more metals (up to nearly twice as much Zn and Pb and three times as much Cd) in roots than the uncontaminated population in a pot trial. In general, however, different populations of T. latifolia showed similar growth responses (the longest leaf elongation, the longest root elongation, shoot and root d. wt), metal uptake and indices of metal tolerance when seedlings were grown in the same metal treatment solutions or in the same metal-contaminated media under laboratory conditions. The data do not support the hypothesis that populations from metal-contaminated sites have evolved tolerance to Zn, Pb and Cd, but rather that T. latifolia shows constitutional tolerance.
