Hyperaccumulators Table – 3
This list covers hyperaccumulators, plant species which accumulate, or are tolerant of, radionuclides (Cadmium, Cd, Caesium-137, Cs-137, Cobalt, Co, Plutonium-238, Pu-238, Radium, Ra, Strontium, Sr, Uranium-234, U-234, Uranium-235, 235, Uranium-238, 238), hydrocarbons and organic solvents (Benzene, BTEX, DDT, Dieldrin, Endosulfan, Fluoranthene, MTBE, Polychlorinated biphenyl, PCB, PCNB, Trichloroethylene, TCE and by-products), and inorganic compounds (Potassium ferrocyanide).

According to Ulrich Schmidt and others, plants' concentration of uranium is considerably increased by an application of citric acid, which solubilizes the uranium (and other metals). * Radionuclides: Cs-137 and Sr-90 are not removed from the top 0.4 meters of s ...

Hyperaccumulator
A hyperaccumulator is a plant capable of growing in soil or water with high concentrations of metals, absorbing them through their roots, and concentrating extremely high levels of metals in their tissues. The metals are concentrated at levels that are Phytotoxin, toxic to closely related species not adapted to growing on the metalliferous soils. Compared to non-hyperaccumulating species, hyperaccumulator roots extract the metal from the soil at a higher rate, transfer it more quickly to their shoots, and store large amounts in leaves and roots. The ability to hyperaccumulate toxic metals compared to related species has been shown to be due to differential gene expression and gene regulation, regulation of the same genes in both plants. Hyperaccumulating plants are of interest for their ability to extract metals from the soils of contaminated sites (phytoremediation) to return the ecosystem to a less toxic state. The plants also hold potential to be used to mine metals from soils ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
