Sep 15, 2006 Normal and phytotoxic concentrations of Pb, Zn and Cu were reported by Levy et al. 1999, which were 0.510 and 30300 mg kg 1 for Pb, 330 and 20100 mg kg 1 for Cu, and 10150 and 100 mg kg 1 for Zn. Almost all collected plant species showed heavy metal concentration higher than the normal or phytotoxic levels.
Accumulation of Pb Cu and Zn in native plants growing on a . Normal and phytotoxic concentrations of Pb Zn and Cu were reported by Levy et al. 1999 which were 0.510 and 30300 mg kg 1 for Pb 330 and 20100 mg kg 1 for Cu and 10150 and 100 mg kg 1 for Zn.
Plants demonstrated differentiated potential on metal accumulation and translocation, and the total Cd, Cu, Pb, and Zn contents in the aerial parts of plants ranged from 5.57 to 268.5, 14.34 to 140.90, 10.43 to 570.3, and 110.3 to 1350 mg kg-1, respectively. Symphytum officinale Linn. distinguished itself from the various plants as a promising ...
Mar 20, 2007 Various extraction procedures were employed for measuring extractable concentrations of potential toxic elements in soil. The extractability of Cd, Cu, Pb and Zn in four contaminated and four non-contaminated soils of Japan, was compared by single extraction CaCl2, DTPA, NH4Cl, 0.1 M HCl and 1 M HCl and sequential extraction procedures six operationally defined chemical phases, viz.
We average our results for Cu, Zn, Pb, Fe, and Al with other estimates Weisel et al., 1984 to arrive at a best estimate. The total sea salt flow to the atmosphere is about 1 10 13 kga, of which 98.5 is deposited back into the ocean, with only the remaining 1.5 deposited onto land Gong et al., 2002
Cd, Cu, Pb and Zn in the soils varied from 0.7 to 12.5, 23 to 133, 19 to 359 and 90 to 704 mgkg, respectively. Generally the concentrations of most metals were 5 to 18 fold higher in the contaminated soils than the non-contaminated soils Table 1. Metals extractability As expected, 1 M HCl was the most efficient extractant Table 3.
Screening of native plant species from mining sites can lead to identify suitable plants for phytoremediation approaches. In this study, we assayed heavy metals tolerance and accumulation in native and dominant plants growing on abandoned PbZn mining site in eastern Morocco. Soil samples and native plants were collected and analyzed for As, Cd, Cu, Ni, Sb, Pb, and Zn concentrations.
May 01, 2002 Six plants of each species, except for Salix where four plants were used, were mounted in black styrofoam plates and placed in 1 l plastic pots filled with 30 nutrient solution with or without the addition of heavy metals. In metal-treatment pots, the elements given were 0.12 M Cd, 2.7 M Cu, 19.8 M Pb, 42.3 M Zn and 6.37 M As.
Oct 20, 2013 Total element concentrations Al, As, Ba, Cd, Co, Cr, Cu, Ni, Pb, Zn, Fe, Mg, Mn, K and Ca were determined after dissolution of the samples with a mixture of 3 concentrated acids 4 mL HCl conc, 2 mL HNO 3conc and 2 mL HF conc. A certified reference material GBW07411 Soil and sample triplicates were used for quality control. Values in mg ...
The Kihabe Zn-Pb-V Cu-Ag-Ge prospect is located at the boundary between Namibia and Botswana Aha Hills, Ngamiland District in a strongly deformed Proterozoic fold belt, corresponding to the NE extension of the Namibian Damara Orogen. The Kihabe prospect contains Zn-Pb resources of 14.4 million tonnes at 2.84 zinc equivalent, Ag resources of 3.3 million ounces, and notable V-Ge
Concentrations of Ag, Cd, Cu, Pb, Sb, and Zn in the initial contaminated soil were 36 times higher than those in the initial clean soil. In particular, contents of Cu, Mo, Ni, Pb, Sb and Zn in roots of the wheat grown in the contaminated soil were higher than those in the roots of the plants grown in the clean soil.
The Kihabe prospect contains Zn-Pb resources of 14.4 million tonnes at 2.84 zinc equivalent, Ag resources of 3.3 million ounces, and notable V-Ge amounts, still not evaluated at a resource level. The ores are represented by a mixed sulfideampndashnonsulfide mineralization.
Plant species that present these adaptations might be useful to mining and other metal pollution restoration programs. This study reports the results for the screening of Ca, Mg, Na, Mn, Fe, Ni, Cu, Zn, As, and Pb in aerial tissues of 97 plant species from the Tinto basin flora.
The stress-resistant exotic olive, Olea europaea exhibited EF of 0.01 for Cu, Cd, and Pb, and 0.29 for Zn, which is characteristic of an excluder plant. Acacia pycnantha, the Australian pioneer legume species with EF 0.03, 0.80, 0.32, and 0.01 for Cu, Zn, Cd, and Pb, respectively, emerged as another strong metal excluder and consequently as ...

Zinc equivalency is based on the following metal price assumptions US18.24oz Ag, US3.05lb Cu, US0.91lb Pb, US1.06 Zn and US1,502oz Au. Metallurgical recovery assumptions are variable between mineralization types, and are based on Yauricocha actual plant data. The average is where recovered 76 Ag, 75 Cu, 89 Pb, 89 Zn, 22 Au.
In a pot culture experiment, five different species of Brassica Brassica juncea, Brassica campestris, Brassica carinata, Brassica napus, and Brassica nigra were grown for screening possible accumulators of heavy metals, viz. Zn, Cu, Ni, and Pb. The plants were grown to maturity in a soil irrigated . Phytoextraction of zinc, copper, nickel and lead from a contaminated soil by different species of Brassica.
Faeces contribute 60 70 of the load of Cd, Zn, Cu and Ni in domestic wastewater and 20 of the input of these elements in mixed wastewater from domestic and industrial premises. Faecal matter typically contains 250 mg Zn kg-1, 70 mg Cu kg-1, 5 mg Ni kg-1, 2 mg Cd kg-1 and 10 mg Pb kg-1 ds. The other principal sources of metals in domestic
Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment raising concerns over their potential effects on human health and the environment.
