1. Introduction. Contamination of soils with metals, including Cd, Pb and Zn, causes soil degradation, which is mostly originated from human activity, posing a threat to soil health and compromising its ability to perform its functions (Kumpiene et al., 2009; Pereira et al., 2018).Mining is one of the main sources of metal pollution for soils, …

concentrations of Pb, Cd, Cu, and Zn were also found in the tanning sludge storage sites (Table2). Meanwhile, met-al concentrations in the soil samples collected from differ-ent sites were highly correlated with Cr-Zn (r =0.671, p < 0.01, N = 16) and Cr-Cd (r = 0.673, p < 0.01, N = 16). These significant correlations indicated a site that
The total average Cu isotope composition for the main mineralization of the Mt Isa Cu–Zn–Pb deposit is 0.00‰, noting that there is significant inter-variability due to inherent variations in chalcopyrite Cu isotope composition (not reflective of analytical uncertainties of individual sample analyses, all typically below 0.1‰). ...

Micronutrients are elements that are essential for plant growth but are required in much smaller amounts (Table 1) than those of the primary nutrients such as nitrogen, phosphorus, sulfur, and potassium.Plants show different needs for certain micronutrients, but the elements that are generally accepted as essential for all higher …
Contamination by heavy metals (HM) is a global concern due to their impact on terrestrial and aquatic environments. This question has great relevance in agricultural areas due to excessive chemical fertilization. In this sense, Cd is a toxic element that can reach agricultural soils through chemical fertilization or sewage sludges. Tobacco plants …

The effect of initial concentration on the adsorption of Pb(II), Cd(II), Ni(II) and Cu(II) using the kaolinite clay was examined with results shown in Fig. 3, where increasing initial metal ion concentration from 10 to 150 mg/L resulted in an increase in the metal ions adsorbed for both single metal and multi-metal competitive adsorption. In general, the …
There are giant gold deposits such as Muruntau, Kumtor and Kalmakyr, world-class copper deposits such as Kalmakyr and Dal'neye, and super-large zinc-lead deposits such as Tekeli in western Tianshan forming a giant Au-Cu-Zn-Pb metallogenic belt, attracting the attention from the world. Yet it is hoped to find gold, copper and zinc-lead deposits significantly in …

Zn (s) + CuSO 4 (aq) → ZnSO 4 (aq) + Cu (s) This concept has several practical applications in the extraction of metals. For example, titanium is extracted from titanium tetrachloride via a single displacement reaction with magnesium. Thus, the reactivity series of metals can also be used to predict the outcome of single displacement reactions.
