Selenium concentrations in the soil environment are directly linked to its transfer in the food
chain, eventually causing either deficiency or toxicity associated with several physiological …

Upland and paddy soils, as well as corn samples, were collected in the selenosis area of
Naore Village, Ziyang County, Shaanxi Province, China. A five-step sequential extraction …

Bacterial anaerobic respiration is one of the most ancient and essential metabolism
processes, possessing the characteristics of both flexibility and high diversity, and a very …

The uptake, accumulation and biological effects of red nano-sized elemental selenium
(nanoSe) in comparison to selenate were investigated in plant system at the first time. The …

Wheat (Triticum aestivum) and its derivative products account for a major source of dietary
intake of selenium (Se) in humans and animals, because of its essentiality due to its …

Background Selenium is a trace element performing important biological functions in many
organisms including humans. It usually affects organisms in a strictly dosage-dependent …

Aims The objective of this study was to determine the relative importance of transpirational
pull, Se speciation, sulfate and species on Se accumulation by plants, in order to determine …

This study investigated the effect of selenate and selenite application on the distribution,
transformation of selenium (Se) fractions in soil, as well as the accumulation and availability …

The ambiguous mechanism that selenite seems to be absorbed by roots via phosphorus (P)
and silicon (Si) transporters signifies P and Si may affect selenite uptake. However, the role …

Abstract The concentrations of Hg, Cu, Pb, Cd, and Zn accumulated by regional
macrophytes were investigated in three tropical wetlands in Colombia. The studied wetlands …
