Background, aim, and scope Heavy metal (HM) mobility in soil depends on the HM species in it. Therefore, knowledge of the HM speciation in soil allows the prediction of HM impact on the environment. HM speciation in soil depends on the metal chemical origin, soil texture, and other factors such as the origin and level of soil contamination. …

The objectives of this study were to characterize and map the spatial distribution of As, Cd, Cu, Pb, and Zn in topsoil at Rayong Province, a rapidly developing city, and to evaluate the associated health risks.

Metal pollution in urban soils due to smelting and electroplating has become a severe problem in China. In this study, the concentration, chemical fraction, and leaching behavior of typical metals (Cu, Zn, Cd, and Pb) in soil samples from ten metallurgical sites were studied. The results show that some of the soils were polluted with Cu and most …

The ({T}_{r}^{i}) values for As, Cd, Cr, Cu, Hg, Pb, Ni and Zn were 10, 30, 2, 5, 40, 5, 5 and 1, respectively.. Potential sources Statistical analysis. The heavy metal concentrations were ...

Functional Trait-Based Screening of Zn-Pb Tolerant Wild Plant Species at an Abandoned Mine Site in Gard (France) for Rehabilitation of Mediterranean Metal-Contaminated Soils ... Compared to mine sites in France, at the Les Malines and Les Avinières near the present study site, the authors detected lower concentrations in Zn and greater in Pb ...

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 …

To investigate and evaluate the spatial distribution of Zn, Pb and Cd in the soil around a municipal solid waste incineration plant and its ecological risks, Zn, Pb and Cd were analyzed in soil samples around a municipal solid waste incineration plant in Chengdu, Sichuan Province, China. The results revealed that the average content of Zn …

To accurately evaluate the pollution and risk of heavy metals in crops and farmlands near mines, we determined the contents of Cr, Ni, Cu, As, Cd, Pb, and Zn in 10 farmland soil sampling sites and six crops …

A Cu-Pb-Zn (copper-lead-zinc) production line is utilized in mining operations to extract and process these valuable metals from ores. The extracted metals have numerous industrial and commercial applications. Here's a detailed look at the uses of each metal and the production line's overall utility: Copper (Cu) Uses of Copper: Electrical ...
