“…BCF and TF values greater than 1 are typical indicators for bioaccumulators (Baker, 1981;Baker and Brooks, 1989;Yoon et al, 2006). Plants are considered useful phytostabilizers if metal concentrations are particularly high in the root system (Fitamo and Leta, 2010). The bioaccumulation factors for the plant species investigated in the Olifants River catchment are shown in Schoenoplectus corymbosus and T. capensis showed BCFs higher than 1 for all three metals.…”

“…The extraction efficiency of a plant depends on the metal concentration and the dry weight of harvestable tissue (Bech et al, 2002;Fitamo and Leta, 2010). The capacity of a plant for phytoextraction and phytostabilization was calculated using Eq.…”

“…The capacity of the seven abundant and widespread riparian plant species (Table 1) to bioaccumulate Al, Fe and Mn was investigated by determining the total metal concentration extracted per plant, root versus shoot tissue accumulation and overall plant biomass (Bech et al, 2002;Fitamo and Leta, 2010). Herein, the possible ecological service they could provide, and potential role in future rehabilitation and remediation efforts along rivers impacted by anthropogenic activities such as acid mine drainage (AMD), could be estimated.…”

“…The TF is the concentration ratio defining the translocation of metals from the roots to the shoots and the TC ratio is that between soil and shoot concentrations (Fitamo and Leta, 2010;Yoon et al, 2006). BCF and TF values greater than 1 are typical indicators for bioaccumulators (Baker, 1981;Baker and Brooks, 1989;Yoon et al, 2006).…”

“…However, the majority of important information concerning heavy metals (HMs) distribution is related to: research on arable crops (Römer et al, 2000;Chan and Hale, 2004;Alexander et al, 2006;Zheng et al, 2008;Mori et al, 2009); natural hyper-accumulators in proximity of industrial plants, waste dumps, and mines (Wong, 2003;Jambhulkar and Juwarkar, 2009;Fitamo and Leta, 2010;Massa et al, 2010;Nganje et al, 2010) ; or the main edificatory species of forest ecosystems -woody plants (Hagemayer, 1986;Andersen et al, 2004;Tyler, 2004;Merino et al, 2008). As such, data for forest herb synusia are scarce or absent.…”

This study addresses the issue of heavy metal (HM) accumulation and distribution for three different plant species, Carex pilosa, Dentaria bulbifera, Galium odoratum, in Carpathian beech ecosystems. Data are presented on HM concentrations in forest understory vegetation and a preliminary insight into different HM allocation patterns is provided. Bioaccumulation factors (BCFs) and shoot/root ratios differed considerably among the species and between polluted and unpolluted regions. HMs were accumulated in forest plants as follows: Cu > Zn > Cd >Pb in unpolluted areas and Zn> Cd > Cu >Pb in polluted areas. Zn was preferentially distributed to roots and Cu to shoots. The distribution of Cd and Pb in different plant parts was specific in terms of the species-dependence. Cd and Pb levels in Carex pilosa and Galium odoratum were more strictly controlled in the transfer zone of root-shoot, compared to Dentaria bulbifera. The highest BCFs were found in Carex pilosa for Cu (5.9) and in Dentaria bulbifera was found the highest shoot/root ratio for Cd (3.1).

Identification and classification of metal-accumulating plant species is essential for phytoextraction. Cluster analysis is used for classifying individuals based on measured characteristics. In this study, classification of plant species for metal accumulation was conducted using cluster analysis based on a practical survey. Forty plant samples belonging to 21 species were collected from an ancient silver-mining site. Five groups such as hyperaccumulator, potential hyperaccumulator, accumulator, potential accumulator, and normal accumulating plant were graded. For Cd accumulation, the ancient silver-mining ecotype of Sedum alfredii was treated as a Cd hyperaccumulator, and the others were normal Cd-accumulating plants. For Zn accumulation, S. alfredii was considered as a potential Zn hyperaccumulator, Conyza canadensis and Artemisia lavandulaefolia were Zn accumulators, and the others were normal Zn-accumulating plants. For Pb accumulation, S. alfredii and Elatostema lineolatum were potential Pb hyperaccumulators, Rubus hunanensis, Ajuga decumbens, and Erigeron annuus were Pb accumulators, C. canadensis and A. lavandulaefolia were potential Pb accumulators, and the others were normal Pb-accumulating plants. Plant species with the potential for phytoextraction were identified such as S. alfredii for Cd and Zn, C. canadensis and A. lavandulaefolia for Zn and Pb, and E. lineolatum, R. hunanensis, A. decumbens, and E. annuus for Pb. Cluster analysis is effective in the classification of plant species for metal accumulation and identification of potential species for phytoextraction.
