Chromium (Cr) is a toxic heavy metal that is heavily discharged into the soil environment
due to its widespread use and mining. High Cr levels may pose toxic hazards to plants …

Selenium (Se) is an essential micronutrient for humans and a beneficial element for plants.
However, high Se doses always exhibit hazardous effects. Recently, Se toxicity in plant-soil …

Accurate prediction of the sorption of perfluoroalkyl substances (PFASs) in soils is essential
for environmental risk assessment. We investigated the effect of solution pH and calculated …

This work was conducted to study the effect of soil pH (4.0, 6.0, and 8.0) on the transport,
fractionation, and oxidation of trivalent chromium [Cr (III)]. Variation in pH altered soil …

Coprecipitation of Fe/Cr hydroxides with natural organic matter (NOM) is an important
pathway for Cr immobilization. However, the role of NOM in coprecipitation is still …

Cr (VI) from oxidation of geogenic Cr (III) minerals is gradually becoming the primary source
of Cr (VI) in soils and groundwater instead of direct emissions. Thermodynamically, natural …

Karst environments are globally significant, and the soils that develop on these landscapes
often have unique geochemical features, including elevated–levels of metals. However, it …

Microorganisms can oxidize Mn (II) to biogenic Mn oxides (BioMnOx), through enzyme-
mediated processes and non-enzyme-mediated processes, which are generally considered …

Fenton reaction is a widely used pretreatment technology to degrade toxic metal–organic
complexes. However, its efficiency is greatly compromised for Cr (III)–organic complexes …

Chromium (Cr) is mainly found in the form of organic-Cr (III) complexes in the natural
environment and industrial waste. The widespread existence of composite contaminants …
