“…According to Chaney et al (1997), for an e ective development of phytoremediation, each element must be considered separately because of its unique soil and plant chemistry. On the other hand, metals rarely occur alone and adaptive tolerance may be needed for several metals simultaneously, even though phytoextraction of only one metal would be the goal.…”

“…A plant cover e ectively prevents contaminant spread by minimizing wind erosion and surface run-o , as well as by reducing percolation to the ground water. Plants may also be used to remove contaminants from soil by phytoextraction and then harvested for processing (Cunningham et al, 1995;Salt et al, 1995Salt et al, , 1998Chaney et al, 1997). There are some promising results suggesting that these techniques might become viable alternatives to mechanical and chemical approaches in remediation of metal contaminated soils.…”

“…There has been intensely increasing interest in understanding the pollution of heavy metals in coastal marsh due to the great influences of human activities (Li et al 2000(Li et al , 2007Caeiro et al 2005;Abrahim and Parker 2008;Bai et al 2011Bai et al , 2012Xiao et al 2013). Exploring heavy metal accumulation in plants for the remediation (or phytoremediation) of coastal environment is of great significance (Chaney et al 1997;Deng et al 2004).…”

To understand the temporal variations and bioaccumulation of heavy metals in the coastal marshes, the concentrations of heavy metals (Cr, Ni, Pb, and Cu) in the two Suaeda salsa marshes [middle S. salsa marsh (MM) and low S. salsa marsh (LM)] of the Yellow River estuary were determined from May to November in 2008 by in situ sampling and inductively coupled plasma mass spectrometry (ICP-MS) analysis. Results showed that heavy metal concentrations in S. salsa of MM and LM were generally in the order of Cu>Cr>Pb>Ni, while those in sediments fell in the order of Cr>Ni>Cu>Pb. Heavy metal concentrations of S. salsa in MM and LM were different, and significant differences were observed in stems (F = 4.797, p= 0.046) and litters (F=6.799, p=0.026) for Ni. Litter was the main stock of heavy metals, and the allocations of Cr, Ni, and Pb reached 31. .64 % (in LM), respectively. The ratios of roots/ leaves (R/L) and roots/stems (R/S) for Cr and Ni in MM were mostly greater than 1, while those ratios in LM were mostly less than 1, indicating that Cr and Ni in S. salsa at LM had greater mobility compared with those at MM. Moreover, the [accumulation factor, AF] plant of Cr, Ni, Cu, and Pb in LM, especially [AF] root and [AF] stem of Cr and [AF] litter of Ni, was also higher than that in MM. These indicated that S. salsa grown in LM was more suitable for potential biomonitor or phytoremediation of Cr, Ni, Cu, and Pb if intertidal sediments were seriously contaminated with an increase of pollutant loading (especially heavy metals) in the Yellow River estuary. The use of biomonitor (S. salsa) living and growing in LM could yield valuable information not only on the presence of anthropogenic stressors, but, more importantly, on the adverse influence the stressors are having on the environment.

Capability of Brassica napus to Accumulate Cadmium, Zinc and Copper from Soil

et al. 2002

The capability of Brassica napus to accumulate soil cadmium, zinc and copper was investigated. The removals of cadmium, zinc and copper from soil by plants, in the fifth week of growth, were calculated by multiplying the heavy metal concentrations by the vegetable biomass production. Plants were cultivated in pots on artificially contaminated soil (50 mg/kg Cd, 600 mg/kg Zn and 600 mg/kg Cu). In contaminated soil, Brassica napus did not show any upper threshold to the absorption of Cd and Zn, hence the removal of these metals from soil was higher than that of the control. In contrast, Cu absorption was poor and the removal of copper from soil did not differ between contaminated soil and control. The results showed that Brassica napus would most likely be more effective in removing cadmium and zinc than copper from the soil.
