Among the plants, Phyla nodiflora was the most efficient in accumulating Cu and Zn in its shoots (TF = 12 and 6.3) while Gentiana pennelliana was most suitable for phytostabilization of sites contaminated with Pb, Cu and Zn (BCF = 11, 22 and 2.6). Plant uptake of the three metals was highly correlated, whereas translocation of Pb was …
The overall metal uptake in plant shoots was lower under DC treatment compared to AC treatment and control, although there was a higher accumulation of Zn and Cu in the plant roots treated with ...
[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 …

Aims The main aim of this study was to validate the HYDRUS-2D model for the simulation of Cd, Cu, Pb and Zn transport within a soil column and their accumulation by willows. Methods A simulation of metal transport and uptake by willow was implemented using the HYDRUS-2D code. Two scenarios of the column experiment were compared: …

Our study shows that several spontaneous and native plants growing on Pb/Zn contaminated sites have a good potential for developing heavy metals phytoremediation strategies. Keywords: phytoextraction; phytostabilization; native plants; heavy metal; …
This study sought to identify plant species with potential for phytoremediation of soils polluted with lead (Pb), zinc (Zn) and copper (Cu) and identified Tephrosia candida and Tagetes minuta and Blotiella glabra (Bory) Tryon as potential plants for phytoextraction of Pb and Stylochaeton natalensis Schott forphytostabilisation of Zn.

Under the optimal conditions, the removal rates of Cu, Zn, and Pb from the soil are 43.9%,73.1%, and 41.5%, respectively. Single-factor experimental studies show a …
About 150 soil samples from 20 urban and 3 non-urban soil profiles in Nanjing were analyzed for total concentrations of Cu, Zn, Pb and Cr using ICP spectrometry. The Cu, Zn, Pb and Cr of 23 urban and non-urban topsoils (A horizon soils) were sequentially extracted into 5 fractions according to the method of Tessier [Anal. Chem. 51 (1979) 844].
For example, 4 found that the formation of aggregates occurred around plant roots in OM-treated Cu-Pb-Zn tailings. Hence, the colonization of native grasses as pioneer plants would be a useful method to improve the aggregation of Cu/Pb-Zn tailings and the resultant physical structure (39; 64). Consequently, the effect of plant growth in the OM ...
Soil in these sites exhibited toxic levels of Cr (averaged 16,492 mg kg−1) and other metals (e.g., 48.3 mg Cu kg−1, 2370 mg Zn kg−1, 44.9 mg Pb kg−1, and 0.59 mg Cd kg−1). Different metal tolerance and accumulation patterns were observed among the sampled plant species.
Bacterial isolates underwent screening for heavy metals tolerance such as Cd/ Cr/ Zn/ Ni/Cu/Sb/As on agar plates containing varying concentration of these metals (Table 3). Lack of growth of the isolates on certain media indicated that the level of heavy was lethal for bacterial proliferation.
