Six plants of each species, except for Salix where four plants were used, were mounted in black styro plates and placed in 1 l plastic pots filled with 30% nutrient solution with or without the addition of heavy metals. In metal-treatment pots, the elements given were 0.12 μM Cd, 2.7 μM Cu, 19.8 μM Pb, 42.3 μM Zn and 6.37 μM As.

Abstract. The uptake and distribution of four heavy metals, including copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn), and those of total phosphorus (TP) in 30 plants in North China were investigated through pot trial experiments. Accumulation and distribution of heavy metals or TP were associated with plant species, tissues, metal elements ...

In this work, native plant species were identified that can tolerate high concentrations of heavy metals and are useful for phytoremediation in an abandoned Pb-Zn mine in the north of Iran. Twelve plant species and the corresponding soils were collected and analyzed for As, Cd, Co, Cr, Cu, Mo, Pb, Sb, Ni and Zn contents using inductively ...

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this …

Such properties have been found in Cardaminopsis halleri for Zn and Cd (Dahmani-Muller et al., 2000) and Thlaspi goeingense for Ni (Krämer et al., 1997). If plants growing on water-saturated mine tailings accumulate Cd, Cu, Zn, Pb and As in the shoot, the elements may be dispersed into the environment through herbivores or at senescence.

The highest BAF of each metal calculated was as follows: Cr (0.091 in winter) > Cu (0.054 in autumn) > Pb (0.016 in summer) > Zn (0.011 in summer). Highest root-rhizome TF values were recorded for four metals: 6.450 for Cu in autumn, 2.895 for Zn in summer, 7.031 for Pb in autumn, and 2.012 for Cr in autumn.
