This table was originally provided by Stevie Famulari for her students at the University of New Mexico Landscape Architecture Department, for a phytoremediation project regarding the drainage canyon of the Manhattan Project at Los Alamos, New Mexico. It has now grown into three sections.

This section covers mainly some toxic metals and informations on the plants used for their remediation.

Cs-137 activity was much smaller in leaves of larch and sycamore maple than of spruce: spruce > larch > sycamore maple.


[edit] Reference sources and notes for the hyperaccumulators table

Notes

  • The references are so far mostly from academic trial papers, experiments and generally of exploration of that field.
  • Alpine pennycress or «Alpine Pennygrass» is found as «Alpine Pennycrest» in (some books).
  • Uranium's symbol is sometimes given as Ur instead of U. According to Ulrich Schmidt[6], plants' concentration of uranium is considerably increased by an application of citric acid, which solubilizes the Uranium (and other metals).

Uptake Kinetics, Interactions with Phosphate, and Arsenic Speciation. Plant Physiol, November 2002, Vol. 130, pp. 1552-1561. 18 days' hydroponic experiment with varying concentrations of arsenate and P. Within 8 h, 50% to 78% of the As taken up is distributed to the fronds, which take from 1.3 to 6.7 times more As than the roots do. No P for 8 days increases the arsenate's maximum net influx by 2.5-fold; the plants then absorbs 10 times more arsenate than arsenite. If on the other hand the P supply is increased, As uptake decreases - with a greater effect on the roots than on the shoots. More arsenate decreases the P concentration in the roots, but not in the fronds. P in the uptake solution markedly decreases arsenate uptake. The presence or absence of P does not affect the uptake of arsenite, which translocates more easily than arsenate.
