This study was conducted to determine the heavy metals of Cd, Mn, Ni, Zn, Pb, Cu, and Cr in two naturally grown plants (Hippophae rhamnoides L. and Pyrus elaeagnifolia Pall.) and on the roadside soil.
Using a global database of 664 hyperaccumulating plants, we constructed a phylogeny of hyperaccumulating plants of As, Cd, Cu, Cr, Mn, Ni, Pb, and Zn. We evaluated the phylogenetic randomness of plants hyperaccumulating different metals by comparing the minimum number of trait-state changes across the phylogenetic tree to a null model.
ABSTRACT: In current time the environment is heavily polluted by various toxic metals, which create a danger for all living beings. Phytoremediation can be potentially used to remediate metal-contaminated sites. A major step towards the development of phytoremediation of heavy metal impacted soils is the discovery of the heavy metal hyperaccumulation in plants. This study …
Among the investigated metals, the plant available Pb and Cd species are the most severe contaminants. Significant correlations between total and DTPA extractable metals were found for Cu (r=0.510) and Pb (0.418), and also an affinity between total and water extractable metals were identified for Cu (0.366), Pb (0.502) and Zn (0.597).

We design and manufacture a wide range of filter presses to dewater coal, mine tailings or minerals ore concentrates, like zinc or copper.
The pairs of Cu–Zn (0.486) and Zn–Pb (0.423) showed high and significant correlations at 99 and 95 % confidence levels, respectively. Furthermore, the linear correlation for soil to leaf transfer showed that between Cd in soil and leaf, there is a high and significant correlation (0.560) at 99 % confidence level.
The sludge was examined for and the total concentrations and different chemical fractions of Cd, Cr, Pb, Cu, Ni and Zn. The total metal concentrations of heavy metals in sludge varied greatly. The contents of Zn and Cu were the highest, followed by then Cr, Ni and Pb and the content of Cd was the least.

Of the metals reviewed, Zn is the least toxic. Generally plant growth is affected at 1000 μg Zn L−1 or more in a nutrient solution, though 100 to 200 µg L−1 may give cytological disorders. At concentrations of 100 to 200 μg L−1, Cu and Cd disturb metabolic processes and growth, whereas the phytotoxicity of Pb generally is lower.
