Accumulation of lead, zinc, copper and cadmium by 12 wetland plant species thriving in metal-contaminated sites in China.
The concentrations of lead, zinc, copper and cadmium accumulated by 12 emergent-rooted wetland plant species including different populations of Leersia hexandra, Juncus effusus and EquisetumExpand
Growth of Vetiveria zizanioides and Phragmities australis on Pb/Zn and Cu mine tailings amended with manure compost and sewage sludge: a greenhouse study.
Plant tissue analysis showed that application of manure compost and sewage sludge could significantly reduce Pb uptake and accumulation, but not Cu in both vetiver and common reed. Expand
Zinc, lead and cadmium tolerance, uptake and accumulation by Typha latifolia.
The data do not support the hypothesis that populations from metal-contaminated sites have evolved tolerance to Zn, Pb and Cd, but rather that T. latifolia shows constitutional tolerance. Expand
Evaluation of major constraints to revegetation of lead/zinc mine tailings using bioassay techniques.
It was found that root elongation provided a better evaluation of toxicity than seed germination, and heavy metal toxicity, especially available Pb, low content of nutrient, and poor physical structure were major constraints on plant establishment and colonization on the Pb/Zn mine tailings. Expand
Natural Colonization of Plants on Five Lead/Zinc Mine Tailings in Southern China
Mine tailings can have a specific assemblage of plant species due to their unique physicochemical properties, and this process can be important in developing ecological theory and restorationExpand
Interactions of mycorrhizal fungi with Pteris vittata (As hyperaccumulator) in As-contaminated soils.
The indigenous mycorrhizas enhanced As accumulation in the As mine populations of P. vittata and Cynodon dactylon and sustained its growth by aiding P absorption, and for C.dactylon, As was mainly accumulated in myCorrhizal roots and translocation to shoots was inhibited. Expand
Lead, zinc and copper accumulation and tolerance in populations of Paspalum distichum and Cynodon dactylon.
Tolerant populations of these species would serve as potential candidates for re-vegetation of wastelands contaminated with Pb, Zn and Cu and suggested that co-tolerant ecotypes have evolved in the two grasses. Expand
Zinc, Lead and Cadmium Tolerance, Uptake and Accumulation by the Common Reed,Phragmites australis(Cav.) Trin. ex Steudel
There was insufficient evidence to support the hypothesis that the metal-contaminated population has evolved to a Zn-, Pb- or Cd-tolerant ecotype but the results indicated some differentiation between the populations with that from Hong Kong being the least productive under the experimental conditions used.

Chemically Assisted Phytoextraction of Heavy Metal Contaminated Soils using Three Plant Species
Phytoextraction is a potential, innovative and cost-effective technology for non-destructive remediation of heavy metal-contaminated soils. A field trial was conducted to evaluate the phytoextractionExpand
Accumulation of total mercury and methylmercury in rice plants collected from different mining areas in China.
Although the degree of Hg contamination varied significantly among different mining areas, rice seed showed the highest ability for methylmercury (MeHg) accumulation, indicating soil is still an important source for both inorganic mercury (IHG) and MeHg in rice plants. Expand
