Abstract Hexavalent chromium (Cr (VI)) is a widespread, toxic contaminant in the
environment. Owing to the increasingly strict requirements for green production and …

Soil contamination by potentially toxic elements (PTEs) has led to adverse environmental
impacts. In this review, we discussed remediation of PTEs contaminated soils through …

Chromium is a highly toxic non-essential metal for microorganisms and plants, and its
occurrence is rare in nature. Lower to higher chromium containing effluents and solid wastes …

In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

The concentration of chromium (VI) in the soil is an important environmental concern due to
its mobility and acute toxicity. Due to its toxicity, removal of this species is very important. The …

The oxygenation of Earth's surface fundamentally altered global biogeochemical cycles and
ultimately paved the way for the rise of metazoans at the end of the Proterozoic. However …

Iron formations (IF) represent an iron-rich rock type that typifies many Archaean and
Proterozoic supracrustal successions and are chemical archives of Precambrian seawater …

In soil environments, sorption/desorption reactions as well as chemical complexation with
inorganic and organic ligands and redox reactions, both biotic and abiotic, are of great …

Groundwater resources in California represent a confluence of high-risk factors for
hexavalent chromium contamination as a result of industrial activities, natural geology, and …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …
