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). See also: *List of hyperaccumulators, Hyperaccumulators table – 1 : Ag, Al, As, Be, Cr, Cu, Hg, Mn, Mo, Naphthalene, Pb, Pd, Se, Zn *Hyperaccumulators table – 2 : Nickel Notes * Uranium: The symbol for Uranium is sometimes given as Ur instead of U. 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 ...

Fluoranthene
Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. The chemical formula is . Although samples are often pale yellow, the compound is colorless. It is soluble in nonpolar organic solvents.Karl Griesbaum, Arno Behr, Dieter Biedenkapp, Heinz-Werner Voges, Dorothea Garbe, Christian Paetz, Gerd Collin, Dieter Mayer, Hartmut Höke “Hydrocarbons” in Ullmann's Encyclopedia of Industrial Chemistry 2002 Wiley-VCH, Weinheim. It is a member of the class of PAHs known as non-alternant PAHs because it has rings other than those with six carbon atoms. It is a structural isomer of the alternant PAH pyrene. It is not as thermodynamically stable as pyrene. Its name is derived from its fluorescence under UV light. Occurrence Traces of fluoranthene is found in many combustion products, along with other PAHs. It results from incomplete combustion. Fluoranthene was originally isola ...

Brassica Juncea
''Brassica juncea'', commonly mustard greens, brown mustard, Chinese mustard, Indian mustard, Korean green mustard, leaf mustard, Oriental mustard and vegetable mustard, is a species of mustard plant. Cultivar ''Brassica juncea'' cultivars can be divided into four major subgroups: integrifolia, juncea, napiformis, and tsatsai. Integrifolia Juncea Napiformis Tsatsai Uses Nutrition In a reference serving, cooked mustard greens provide of food energy and are a rich source (20% or more of the Daily Value) of vitamins A, C, and K—K being especially high as a multiple of its Daily Value. Mustard greens are a moderate source of vitamin E and calcium. Greens are 92% water, 4.5% carbohydrates, 2.6% protein and 0.5% fat (table). Cuisine The leaves, seeds, and stems of this mustard variety are edible. The plant appears in some form in African, Bangladeshi, Chinese, Filipino, Tripuri, Italian, Indian, Japanese, Okinawan, Nepali, Pakistani, ...

Brassicaceae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important Family (biology), family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in Rosette (botany), rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetable ...

Bacopa Monnieri
''Bacopa monnieri'', also known as water hyssop, brahmi, thyme-leafed gratiola, herb of grace, and Indian pennywort, is a perennial, creeping herb native to wetland areas globally. It is used in Ayurveda. In 2019, the US Food and Drug Administration (FDA) warned manufacturers of dietary supplement products containing ''Bacopa monnieri'' against making illegal and unproven claims that the herb can treat various diseases. There is inconclusive evidence of it improving cognitive performance and memory, and its safety and effectiveness remain uncertain. Description ''Bacopa monnieri'' is a non-aromatic herb. The leaves of this plant are succulent, oblong, and thick. Leaves are oblanceolate and are arranged oppositely on the stem. The flowers are small, actinomorphic and white, with four to five petals. It can even grow in slightly brackish conditions. Propagation is often achieved through cuttings. Ecology ''Bacopa monnieri'' is one of the most widespread ''Bacopa'' species. ...

Avena Strigosa
''Avena strigosa'' (also called lopsided oat, bristle oat or black oat; syn. ''Avena hispanica'' Ard.) is a species of grass native to Europe. It has edible seeds and is often cultivated as animal feed in southern Brazil. It is sometimes reported as a weed. Description ''Avena strigosa'' is a tufted grass growing to a height of 0.8–1.5 m. Its seeds are smaller than those of the common oat The oat (''Avena sativa''), sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name (usually in the plural). Oats appear to have been domesticated as a secondary crop, as their seeds ..., ''Avena sativa''.Heuzé V., Tran G., Hassoun P., Lebas F., 2015. Black oat (Avena strigosa).

Athyrium Yokoscense
''Athyrium yokoscense'', commonly known as Asian common ladyfern in English and as ''Hebino-negoza'' in Japanese, is a species of fern in the family Athyriaceae. These tough plants live primarily in and around mine sites and thrive in soils contaminated with high concentrations of heavy metals, such as zinc, cadmium, lead, and copper. ''A. yokoscense'' is indigenous to Japan, Korea, eastern Siberia and northeastern China and has been known for centuries to tolerate phytotoxic mining sites. The predominance and concentration of this fern species at a particular region was used to identify potential mining sites. The primary potential of ''A. yokoscense'' is in its phytoremediative ability to accumulate toxic metals from soils contaminated with heavy metals, so it may have some long-term commercial importance. No medicinal or culinary values of this fern species have been studied or confirmed. Morphology ''A. yokoscense'' is similar to other species in the g ...

Nickel
Nickel is a chemical element; it has Chemical symbol, symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and Ductility, ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under Standard temperature and pressure, standard conditions because a Passivation (chemistry), passivation layer of Nickel(II) oxide, nickel oxide forms on the surface that prevents further corrosion. Even so, pure native metal, native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger iron meteorite, nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric iron, Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer core, Earth's outer a ...
