No
Yes
The list below are considered as heavy metals except:
Lead (Pb)
Mercury (Hg)
Cadmium (Cd)
Arsenic (As)
Phytoremdiation basically refers to use plants and associated soil microbes to reduce the concentrations or toxic effects of contaminants in the environment
No
Yes
All plants have the ability in accumulating all elements including heavy metals
No
Yes
The metal hyperaccumulator plants is the term introduced by Brooks (1977) which refer to plants which can accumulate more than 10 mg metal/g dry mass in the leaves
No
Yes
The series of the metals uptake by metal hyperaccumulators are as list below except:
Root uptake
Phloem loading
Xylem loading
Sequestration
Phytoextraction is the technique involves in stabilizing soil contamination by complexation, precipitation or root absorption rather than clean up
No
Yes

Phytoextraction
Rhizofiltration
Phytodegradation
Phytoexclusion
