In this work native plant species were identified that can tolerate high concentrations of heavy metals and are useful for phytoremediation in an abandoned Pb Zn mine in the north of Iran Twelve plant species and the corresponding soils were collected and analyzed for As Cd Co Cr Cu Mo Pb Sb Ni and Zn contents using inductively
According to BCF TF and BAC these plant species could be used as effective plants for Pb phytoextraction Stipa tenacissima and Artemisia herba alba are better suited for phytostabilization of Cd/Cu and Cu/Zn respectively Our study shows that several spontaneous and native plants growing on Pb/Zn contaminated sites have a good potential
[Background] Plant growth promoting bacteria PGPB have good potential in assisting phytoremediation of heavy metal pollution due to their advantages in promoting the growth and heavy metal resistance of plants In heavy metal contaminated soils indigenous PGPB can better colonize and exert their plant growth promoting abilities [Objective] Our aim is to isolate the
The pollution status of ten potentially toxic elements PTEs isotopic compositions Cu Zn Pb and the potential ecological risk posed by them were investigated in the PM10 fraction of road dust in Busan Metropolitan city South Korea Enrichment factors revealed extremely to strongly polluted levels of Sb Cd Zn Pb and Cu in the PM10 fraction of
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 elements of P Cd Cu Pb Se and Zn were further investigated Cu Cd Pb and Zn are frequently studied metals Goodyear and McNeill 1999 as elevated levels might be toxic to organisms Zn and Cu are essential trace metals; whereas Cd and Pb are in general considered non essential Rainbow 2002; Hejna et al 2018 P is an
The Pb Cd Cr Cu and Ni contents in oolong tea fell below the limit stipulated in the related standards GB 2762 2012 NY 659 2003 and NY/T 288 2012 while the Pb and Cu contents in the green tea samples as well as a few black Pu er and jasmine tea samples exceeded the limit
A field survey of higher terrestrial plants growing on Lanping lead zinc mine China were conducted to identify species accumulating exceptionally large concentrations of Pb Cd Cu and Zn of 20 samples of 17 plant species Concentrations of Pb and Zn in soil and in plant were higher than that of Cu and Cd Significant difference was observed

Both background concentrations and risk based values have been used to establish cleanup target levels Background concentrations of trace metals can be used as a reference to evaluate if a site is contaminated Ma et al 1997 In Florida the Soil Cleanup Target Levels SCTLs for trace metals in contaminated soils were established based on human

The uptake and distribution of four heavy metals including copper Cu cadmium Cd lead Pb and zinc Zn and those of total phosphorus TP in 30 plants in North China were investigated through pot trial experiments Accumulation and distribution of heavy metals or TP were associated with plant species tissues metal elements and pollutant
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
Toxic metals such as As Cd Cr Cu Hg Pb and Zn have been wildly distributed in the environment [] Their presence in soil has raised a major concern for human health [1 2] Excessive amounts of heavy metals in soil can affect both the quality and quantity of functioning biota and thus ecosystems in general [3 4 5 6 7] Anthropogenic activities release
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 Pb/Zn mining site in eastern Morocco Soil samples and native plants were collected and analyzed for As Cd Cu Ni Sb
In the case of Zn CaCl 2 extractable concentrations decreased significantly both with or without plants while the DTPA extractable Zn concentration in the soils with plants slightly increased
