“…In general, the heavy metal concentrations in the plant tissues decreased in sequence of Mn4Zn4Cu4Pb4Cr Ni4Cd. The roots of aquatic plants accumulate higher amount of metal than the stems and the leaves (Aksoy et al, 2005;Goulet et al, 2005;Choo et al, 2006;Duman et al, 2006). In this study, Mn concentrations were found higher in leaves during all seasons.…”

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.

“…In this study, the studied heavy metals underwent seasonal change and there was an increase in heavy metal concentrations generally in spring. The reason was that spring growth was characterized by a rapid uptake of nutrients and trace elements (Duman et al 2006). Grudnik (2010) found similar results as of this study that the concentrations of heavy metals such as Cr, As and Pb in M. spicatum plant were more in spring than any other season.…”

“…Furthermore, as reviewed also by Weis and Weis (2004), there are conflicting reports regarding the influence of changes in the season and/or sampling time on the trace metal accumulation and its partitioning in plant parts. In general, plants accumulate the sediment-associated trace metals and transfer/partition these metals to aerial parts mainly during the growing season which in turn may be influenced by seasonal fluctuations/ variation as reported by Caçador et al (2000), Duman et al (2006) and Homyog et al (2008). Some researchers have reported the highest metal contents during autumn and relatively low levels during spring (Brekken and Steinnes 2004), whereas others have indicated the highest foliar metal levels during spring and the lowest during winter (Martin and Coughtrey 1982).…”

The availability of metals to plants is a complex function of numerous environmental factors. Many of these factors are interrelated, and vary seasonally and temporally. The current study intended to understand the influence of seasonal fluctuations and the vegetation of salt marsh plants (SMPs; Halimione portulacoides, Juncus maritimus) on sediment's mercury (Hg) and its pH and redox potential (Eh), as well as their cumulative effect on the plant's Hg-accumulation and Hg-partitioning potential. The area selected for the study was Laranjo Basin at Ria de Aveiro lagoon (Portugal) where a known Hg gradient was existed due to chlor-alkali plant discharge. Three sampling sites (L1, L2 and L3) were selected along a transect defined by the distance from the main Hg source. Samples were also collected from the Hg-free site (R). Irrespective of the plant vegetation, Hg in sediments gradually increased with a decreasing distance towards Hg-point source. The sediment colonised by J. maritimus showed more Hg concentration compared with H. portulacoides irrespective of the season. As a whole, J. maritimus accumulated Hg more than H. portulacoides at all the sampling sites, whereas in root, stem and leaf, the concentration was ranked as: L1 > L2 > L3 in both the plant species and was differentially influenced by seasonal changes. Moreover, root of both plants exhibited highest Hg concentration compared with stem and leaf. In addition, the leaf of H. portulacoides exhibited more Hg than leaves of J. maritimus. Bioaccumulation and translocation factors and dry weight were differentially influenced by seasonal changes. Taking together the results, the physicochemical properties of sediment especially the sediment-Eh seems to be influnced by the type of plant vegetation and seasonal changes which in turn may have influenced the chemistry of sediments; thus, it enfluences the bioavalability of Hg and the Hgretention capacity of both salt marsh sediments (SMSs) and SMPs (bioaccumulation factor). Moreover, SMSs vegetated by J. maritimus exhibited a stronger capacity for the retention and phytostabilization of Hg belowground (in sediments and/or roots) than those dominated by H. portulacoides. ConverseWater Air Soil Pollut (2011) 222:1-15 ly, those SMSs extensively vegetated by H. portulacoides are expected to translocate more Hg to aboveground parts, acting as a potential source of this metal to the marsh ecosystem. Therefore, J. maritimus and H. portulacoides may be used repectively for phytostabilization (in rhizosediments) and phytoextraction (by accumulation in aboveground plant tissue for subsequent plant removal).
