Heavy metal distribution and chemical speciation in tailings and soils around a Pb-Zn mine in Spain.
TL;DR: Comparison of the results with several criteria reported in the literature for risk assessment in soils polluted by heavy metals showed the need to treat the mine tailings dumped in the mine area.

Adsorption of Cu(II) by biochars generated from three crop straws
TL;DR: In this article, the authors used the Langmuir equation to predict the adsorption capacity of the biochars, with maximum predicted adaption in the ranges 0.58-1.40 and 0.48-0.79-mol/kg at pH 5.0 and 4.5, respectively.

Human health risk from soil heavy metal contamination under different land uses near Dabaoshan Mine, Southern China.
TL;DR: Investigating heavy metal contamination near Dabaoshan Mine using sequential indicator simulation to delineate the spatial patterns of soil data, and fitting multiple linear regression models for heavy metal uptake by crops, indicates that Cd is the most important pollutant contributing to the human health risk.

Redox-Controlled Changes in Cadmium Solubility and Solid-Phase Speciation in a Paddy Soil As Affected by Reducible Sulfate and Copper
TL;DR: In multimetal contaminated paddy soils with low sulfate contents, Cd may remain labile during soil flooding, which enhances the risk for Cd transfer into rice and suggests that Cd-sulfide formation in flooded paddy soil may be limited when the amounts of Cd and other chalcophile metals significantly exceed reducible sulfate.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.
