This study aims to compare the chromium (Cr) mobility in two soils with different Cr sources. The first one is an anthropogenically contaminated soil from an area of a piston ring production factory, and the second one is a serpentine soil with a nat

Abstract We studied the dust fractions of the smelting slag, mine tailings, and soil from the former Ni‐Cu mining and processing district in Selebi‐Phikwe (eastern Botswana). Multi‐method chemical and mineralogical investigations were combined

Ore mining and processing in semi-arid areas is responsible for the generation of metal(loid)-containing dust, which is easily transported by wind to the surrounding environment. To assess the human exposure to dust-derived metal(loid)s (As, Cd, Cu,

Extensive mining and smelting contributed to the declining quality of Luanshya soils. The local smelter was the epicenter of contamination as shown by a spatial distribution analysis. Closeby soil profiles smelter exhibit extremely high Cu concentrat

Phosphate competition with arsenic is one of the leading causes of As release from sediments into freshwaters. An important P source to freshwaters is wastewater treatment plants (WWTP), estimated to contribute 25–45% of all P in surface waters.A s

The purpose of this study was to investigate the key geochemical and mineralogical factors that could affect the fractionation of stable thallium (Tl) isotopes in soil. A set of grassland soil samples enriched in geogenic Tl in combination with selec

Humidity is an important factor in sulfide oxidation as it has been shown that sulfide minerals weather differently depending on the humidity. Arsenopyrite (FeAsS) and löllingite (FeAs2) concentrates were placed under six relative humidities (RH) be
