 — Unlike Cr, Cu, Cd, and Pb, the maximum Zn concentration was not found in plants at site HN-4 or HN-5, but in A. philoxeroides (365 mg kg −1) at site HN-3. Furthermore, Z. candida and C. dactylon at site HN-2 and even C. rotundus at Site HN-6 contained Zn concentrations greater than 200 mg kg −1, exceeding the highest Zn …

 — 1. Introduction. Globally, epithermal deposits host significant amounts of Cu, Pb, and Zn as well as other economically important elements such as In and Te (Hedenquist et al., 2000; Sillitoe and Hedenquist, 2003).These metals commonly occur in sulfides, mainly as chalcopyrite (CuFeS 2), galena (PbS), and sphalerite (ZnS); …

 — Tea is known as an inevitable and important part of a healthy and balanced diet. However, it might be contaminated by heavy metals via many ways, including irrigation by sewage water, industrial effluents, sewage sludge, vehicular emissions, industrial wastes, and atmospheric deposition.

 — The Zn isotopes signature related to slag materials at Pb and Zn smelting sites can exhibit a large range of δ 66 Zn: 0.81 ± 0.20‰ (Juillot et al., 2011), 0.37–0.43‰ from Pb–Zn refinery (Couder et al., 2008), 0.85 ± 0.74‰ from Belgian Zn refinery (Sonke et al., 2008), 0.18–1.49 ± 0.04‰ for tailings at a former French Zn ...

 — The Southern Permian basin in central Europe contains a number of important high-grade sediment-hosted Cu deposits. Laterally extensive stratabound Cu and Zn-Pb sulfide mineralized rocks are located at a major stratigraphic redox boundary, where coarse-grained continental sandstones of the uppermost Rotliegend Group are overlain …

 — Zn and Pb smelters are the major contributors to Zn and Pb emissions among all anthropogenic sources, thus, it is essential to understand Zn isotopic variations within the context of metallurgical industries, as well as its fractionation in different environments impacted by smelting activities.This mini review outlines the current state of knowledge …

 — The effectiveness of immobilization was evaluated by analyzing the leachable fraction of heavy metals from the ball-milled soil. When the milling time was 2 h, Pb, Cu, …

Knowledge of normal levels of concentrations of trace elements (Cd, Pb, Hg, Cu, Zn, and Se) in the population serves, among others, in design of regulations concerning health protection, determination of exposition limits and prevention of diseases caused by deficiency of trace elements. Concentrati …

 — This study was conducted to investigate the pollution load index, fraction distributions, and mobility of Pb, Cd, Cu, and Zn in garden and paddy soils collected from a Pb/Zn mine in Chenzhou City, China. The samples were analyzed using Leleyter and Probst's sequential extraction procedures. Total metal concentrations including Pb, Cd, …

 — Additional benefits can be realised by implementing energy-efficient grinding technologies downstream of the HPGR circuit. Stirred mills/tower mills are more energy-efficient than conventional ball mills because they use much smaller grinding media in regrinding and fine grinding operations; a ∼50 % reduction in energy compared with ball …

The release of in situ heavy metals (cadmium [Cd], copper [Cu], lead [Pb], manganese [Mn], and zinc [Zn]) from contaminated river sediment near a Cu-iron mine in South China was experimentally studied. The effects of pH values and the kinetics of heavy metal release were investigated. In addition, s …

 — Changes in soil pH may cause heavy metals to be released again, however, ball milling can enhance the anti-acid ability of soils. After ball milling, the leaching …

The results showed that the concentration of Cu, Zn, Mn, Ni were higher, but Pb, Cr much lower. Although the contents of heavy metals were higher than the background values of Pearl River Delta crop soil, except for Cu contents in the selected sludge, the other elements meet the controlled standards of pollutants in sludge for agricultural uses ...
