The accumulation of heavy metals in agricultural soils is of increasing concern because of food safety issues potential health risks and its detrimental effects on soil ecosystems McLaughlin et al 1999 Cui et al 2004 Hg Pb and Cd are of great concern because of their toxicity to human health and other organisms whereas Zn and Cu are
The absorption and accumulation of Pb Zn Cu and Cd in some endurant weed plant species that survived in an old smeltery in Liaoning China were systematically investigated Potential hyperaccumulative characteristics of these species were also discussed The results showed that metal accumulation in plants differed with species tissues and metals Endurant

Soil contamination caused by heavy metals has gained widespread attention from both government and public In the present research ball milling was utilized to remediate soil contaminated by Pb Cu and Zn and the influence of milling time on immobilization effectiveness was also investigated The effectiveness of immobilization was evaluated by analyzing the
An exploratory study on soil contamination of heavy metals was carried out surrounding Huludao zinc smelter in Liaoning province China The distribution of total heavy metals and their chemical speciations were investigated The correlations between heavy metal speciations and soil pH values in corresponding sites were also analyzed In general Cd Zn
Soil is a medium of crucial importance for plants animals and human beings the soil samples were unified concerning the fraction size by grinding them in a planetary mill Planetary Ball Mill PM 100 Retsch toxic heavy metals Pb Cd Cr and Ni were examined using a reference method The bioavailable forms of Cd Cu Pb Ni Cr
From the Middle Ages until the beginning of the twentieth century extensive Zn Pb mining and smelting was carried out in East Belgium By lack of waste treatment techniques and sustainable management practices metal bearing slags and unprocessed waste were dumped in huge tailings which still represent an important source of contamination A
[Element] shoot [Element] root ratios in fi eld plants white bars and in plants treated for 1 week with a solution containing m M Cd m M Cu m M Pb m M Zn and m M As
Using a global database of 664 hyperaccumulating plants we constructed a phylogeny of hyperaccumulating plants of As Cd Cu Cr Mn Ni Pb and Zn We evaluated the phylogenetic randomness of plants hyperaccumulating different metals by comparing the minimum number of trait state changes across the phylogenetic tree to a null model Based on
High levels of Zn ± μg g⁻¹ were found in plant tissue compared to Pb ± μg g⁻¹ and Cu ± μg g⁻¹ Toxicological endpoints correlated with metal
ABSTRACT In current time the environment is heavily polluted by various toxic metals which create a danger for all living beings Phytoremediation can be potentially used to remediate metal contaminated sites A major step towards the development of phytoremediation of heavy metal impacted soils is the discovery of the heavy metal hyperaccumulation in plants This study
Simultaneous adsorption of Cu II Zn II Cd II and Pb II from synthetic wastewater using NaP and LTA zeolites prepared from biomass fly ash was collected from a co incineration plant of a paper mill located in Southeast Finland where bark natural gas wastewater sludge wood chips and recycled wood are utilized as the fuel source
For example after investigating 15 species of aquatic plants from contaminated urban streams Cardwell et al 2002 found that the roots had higher concentrations of metals Cd Cu Pb and Zn
Hyperaccumulators the plant species that can accumulate 1000 mg Ni Cu Co Cr and Pb 100 mg Cd and 10 000 mg kg −1 Zn and Mn dry weight may be emphasized for the phytoextraction Garcıa et
The results of the concentrations of four heavy metals Cu Cd Pb and Zn determined from wastewater samples from Gusii treatment plant are shown in table concentrations of Zn and Cadmium Cd
In the Lingchuan Daoping and Xinglu Pb Zn ore fields in northern and eastern Guangxi Autonomous Region Pb Cu botanogeochemical anomalies may be ascribed to the excessive amounts of Pb and Cu taken up by the root system of plants such as China fir Cunninghamia lanceolata Lamb Hook mason pine Pinus massoniana Lamb and bracken fern Pteridium
example addition of P to a soil contaminated with Pb Zn and Cd reduced the bioavailable Pb but increased plant Cd concentrations [19] Phosphate rock was effective in reduced Pb in physiologically
The remediation of Pb Cd and Zn contaminated soil by ex situ EDTA washing was investigated in two pot experiments We tested the influence of i 0 and %wt zero valent iron ZVI and ii a combination of 5%wt vermicompost 2%wt biochar and 1%wt ZVI on the metal availability in EDTA washed soil using different soil extracts Aqua regia
gistic effect of Cl K Ca Cr Mo Ba and Pb sulphur presumably is present in higher concentrations in the form of various compounds mainly in winter but
The study presents results from 6 months of phytoremediation of sediments dredged from three urban retention tanks carried out in a mesocosm setup with the use of P kinds of P australis seedlings were considered seedlings originating from natural uncontaminated S uncont and anthropogenically changed environments contaminated S
Copper Cu is an essential mineral nutrient for the proper growth and development of plants; it is involved in myriad morphological physiological and biochemical processes Copper acts as a cofactor in various enzymes and performs essential roles in photosynthesis respiration and the electron transport chain and is a structural component of
