“…The presence of these oxides and the release of their colloidal forms into the water extracts seems to contribute to lead solubility. This result contradicts the suggestion of several authors that Pb is strongly associated with reducible fractions (Fe and Mn oxides phases) [29,[58][59][60].…”

“…The tailings material was alkaline and within similar ranges reported by Iavazzo et al (2012) for Pb/Zn mine wastes from arid parts of Morocco (pH 7.9-8.5). The pH KCl was higher than the pH water , which was attributed to the displacement of base cations from the tailings in the salt-buffered solution.…”

Tailings from a lead/zinc (Pb/Zn) mine were characterised and their revegetation potential investigated under glasshouse conditions using five grass species with three rates of inorganic fertiliser. The tailings were alkaline with low nutrient concentrations but high total and extractable Zn. The yield of all grass species increased with an increase in fertiliser rate. The yield of Cenchrus ciliaris at the full fertiliser application rate was significantly higher than the other species tested, followed by Digitaria eriantha. Cymbopogon plurinodis was the third-highest-yielding species, whereas yields of Eragrostis superba and Fingeruthia africana were similar. Concentrations of Zn in the foliage tended to be over the reported grass foliage ranges, whereas Pb concentrations were within typical norms. It is recommended that C. ciliaris, D. eriantha and E. superba be used for initial revegetation, with other species used to improve biodiversity after initial cover has been established.

“…Mining and smelting processes discharge large quantities of heavy metals into the environment via wastewater, dust, tailings, and residues. Irrigation using polluted water [11], atmospheric deposition [12], and waste disposal [13,14] are main conduits that pollute soils with heavy metals. In the Jiangxi Province of China, many non-ferrous mines and smelters are scattered on both sides of the Jishui River, which is one of the tributaries of the Le'an River.…”

The vertical distribution of Cd, Cr, Cu, Pb, and Zn and their mobility (except Cr) were investigated in ten agricultural soil cores, collected near non-ferrous metal mines and smelters along Jishui River, in Jiangxi Province, China. The surface soils near mines and smelters were contaminated by Cd, Cu, Pb, and Zn, with concentrations higher than the guideline values of China. For most polluted sites, heavy metals were mainly retained in the surface soil (0-20 cm), and the contents of them became constant in deeper soil. In all soil cores, the mean content of Cr was lower than the guideline value of China. Correlation results between studied heavy metals and soil properties showed that heavy metal contents throughout the soil profile was mostly influenced by organic matter (OM), pH, and clay content. Particularly soil OM can significantly impact on transport of soil heavy metals. There were positive correlations of OM content with all studied heavy metals, and the correlations with Cr, Cu, Pb, and Zn were significant or very significant. Heavy metal mobility in the studied region were assessed using a mobility index (MI) and mobility order was Cd ) Pb > Cu % Zn.
