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

Ultramafic soils are in equal parts fascinating and dangerous. Developed on rocks derived
predominately from the Earth's mantle and metamorphosed at the ocean floors, ultramafic …

Ultramafic outcrops could represent up to 3% or more of the terrestrial surface and their
unusual geochemistry makes them a global hotspot for biodiversity. Ultramafic soils are a …

Abstract Knowledge on the redox geochemistry of Ni is behind in comparison to other heavy
metals. Hence, this article reviews the direct and indirect impact of redox potential (EH) on …

Although several laboratory studies showed that Mn-oxides are capable of oxidizing Cr (III)
to Cr (VI), very few have reported evidence for such a reaction in natural systems. This study …

Metallurgical industries remain a considerable source of trace element contamination and
potential human health risk. Determination of sources is a key challenge. With respect to the …

Chromium (Cr) leached from iron (Fe)(oxyhydr) oxide-rich tropical laterites can substantially
impact downstream groundwater, ecosystems, and human health. However, its partitioning …

Basalt-derived soils are widespread worldwide. Such soils contain high levels of heavy
metals like chromium (Cr), which is a serious environmental concern. However, little is …

This study investigated trace element contamination in honey bees inhabiting urban areas
around the South Pacific's largest and longest operating nickel smelter in Nouméa, New …

Rice is one of the most important staple foods worldwide. Soil contamination with heavy
metals and food safety problems occur in many countries as a result of numerous human …
