39 indigenous plant species in 18 families were collected and investigated in four heavy-metal polluted sites. The tolerance and hyptoextraction characteristics of them to Cd, Pb, Cu, Zn and As were examined. In field survey, Bidens bipinnata, Artemisia dubia, Polygonum lapatuifolium, Chenopodium ambrosioides and Solanum nigrum showed to concentrate remarkable heavy metal in shoots. In the further...
The concentration of eighteen nutrients and heavy metals in E. crassipes collected from different sites in the North Zhejiang, China was concurrently studied. The concentration of the elements in whole plants was in the order of K (14896.92 μg g-1)>P (5775.78 μg g-1)>S (5596.38 μg g-1)>Ca (2368.92μg g-1)>Pb (2380.03 μg g-1)>Mn (852.90 μg g-1)>Fe (782.63 μg g-1) >Al (456.26 μg...
Soil pollution is a worldwide problem. Both inorganic and persistent organic pollutants (POPs) possess high toxicity and long-term persistence. Biosurfactant based remediation technologies for contaminated soil are of increasing importance recently, and they have been demonstrated to be effective in uptaking both heavy metals such as Cd, Pb, Zn, Cu, and organic pollutants like hydrophobic organic...
A facultative halophite Mesembryanthemum crystallinum L. (the common ice plant) was shown to grow successively at the high concentrations of Cu and Zn. Although 25 µM CuSO4 or 800 µM ZnSO4 retarded markedly plant growth, they did not interfere with the completion of plant development and the formation of viable seeds. In such plants, leaves accumulated more than 200 µg of Cu and 1700 µg of Zn per...
