Phytoremediation is one of the cost-effective and environmental friendly technologies used to remove contaminants from contaminated soils, which has been intensively studied during the last decade. Presently, few economical and effective remediation methods are available for the remediation of Pb contaminated sites. This study was conducted to assess the potential of 19 plants growing on contaminated sites in Pb mine area. Plants and associated soil samples were collected and analyzed for total metal concentrations. While total soil Pb, Cu and Zn concentrations varied from 1,239 to 4,311, 36 to 1,020 and 240 to 2,380 mg/kg, those in the plant shoots ranged from 6.3 to 2,029, 20 to 570, and 36 to 690 mg/kg, respectively. Among the plants, we found that one cultivated crop (Ricinus communis L.) and two native species (Tephrosia candida and Debregeasia orientalis) have a great potential for phytoremediation of Pb contaminated soils, the Pb hyperaccumulation capacity of the 3 plants was found as the order: R. communis > D. orientalis > T. candida in the investigated area.

“…Although the root length of E. splendens from Tongling decreased slightly, root length of the other two E. splendens ecotypes increased slightly at elevated Cu levels. The tolerance indices of the three E. splendens ecotypes were calculated by the equation described by Shu et al (2002) as follows:…”

The effects of copper (Cu) on the yield and Cu uptake of three ecotypes of Elsholtzia splendens and one of Elsholtzia argyi were studied using solution culture. Three Cu concentrations were compared: 0.31 (control), 50 and 100 Amol L . In contrast, plants from all three populations of E. splendens showed high Cu tolerance and substantial shoot Cu accumulation of 58 -144 mg kg À 1 . Shoot Cu concentrations were about 16 -27 times higher than root Cu concentrations. Root-to-shoot ratio of the E. argyi ecotype was halved when Cu was supplied at a level of 100 mg L À 1 compared to the control (0.31 mg L À 1 ) but the ratio increased by 6 -47% in the three E. splendens ecotypes. The increase in root-to-shoot ratio in E. splendens may be a mechanism by which the plants can tolerate high Cu concentrations. There were few differences in morphology among the three E. splendens ecotypes in response to added Cu. The results are discussed in relation to the possible use of E. splendens as a pioneer species in the phytostabilization of Cu-contaminated soils. D

“…In general, bioavailable Ni concentration is found higher in FA than TS, but its translocation to the shoot is less, like Pb and Co (TF<1). The Pb concentration was higher in FA (root: 5 mg kg -1 ; shoot: 3 mg kg -1 ) than TS, but well within the concentration of normal soil (root: 18 mg kg -1 ; shoot: 12 mg kg -1 ) (Shu et al, 2002), whereas hyperaccumulator plant has potential to accumulate more than 1000 mg Pb per kg dry wt (Reeves and Brooks, 1983). Studies showed that phytoavailability of Pb increase with increased level of Pb in soil.…”

Maiti et al.: Comparative study on bioaccumulation and translocation of metals inAbstract. Cynodon dactylon (Bermuda grass) is one of the most common naturally colonized creeper grass found on fly ash lagoons and soils in India. Bioavailable metal concentrations in fly ash and topsoil were analyzed by using DTPA as extractant. Bioaccumulation of metals in the root and their translocation to the shoot were estimated for fly ash and compared with topsoil. Bioaccumulation of Zn, Mn, Ni and Cu were found similar for the plants growing on fly ash and topsoil. Different bioaccumulation trends were observed for Pb, Co and Cd, in fly ash and topsoil. In fly ash translocation factors were found >1 for Cd, Mn, Zn and Cu, indicating a higher translocation of these metals in aerial parts, which can easily transfer to the food chain. In topsoil, translocation factor for all the metals (except Cd) was found <1, indicating immobilization of metals in root. The study concluded that Bermuda grass growing on fly ash lagoons can act as a transferring link of heavy metals in the food chain.
