Oxides and their precursors have been extensively studied, either singly or in combination
with other amendments promoting sorption, for in situ stabilization of metals and As in …

Free of human interference the soil trace element content is largely dependent on that of the
soil parent material and acting weathering processes. An increasingly industrialised society …

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 …

The sources and potential availability of chromium (Cr) on soils formed on ultramafic rocks
were investigated with mineralogical studies and selective chemical extractions. Soil …

Aerobic and anaerobic incubation experiments on a wetland soil samples were used to
assess the respective roles of organic matter (OM) release, Fe-oxyhydroxides reduction and …

Concern about health effect of Potentially Toxic Elements (PTEs) has led to an increasing
global attention about their concentration levels in the environment. Soil geochemistry has …

Abstract The European Union recently updated the list of raw materials considered as critical
for its industry on the basis of their high economic importance and their relative supply risk …

Nickel, a potentially toxic metal, is present in all soils with an average concentration of 20 to
30 mg/kg, sometimes exceeding 10,000 mg/kg (eg, ultramafic soils). The ecotoxicological …

Ultramafic rocks and their related soils and sediments are non-anthropogenic sources of
metal contaminants. In the southeastern region of Sri Lanka, release of Ni and Mn into the …

Changes in Ni speciation in a 64m vertical profile of a New Caledonian saprolitic–lateritic
regolith developed over ultramafic rocks under tropical weathering conditions were …
