Selenium (Se) is an essential trace element for humans and animals, although controversial
for different plant species. There exists a narrow line between essential, beneficial and toxic …

Selenium is an indispensable trace element for humans, however, its release at high
concentrations becomes a major concern for terrestrial and aquatic ecosystems due to its …

Selenium (Se) is an essential element for humans and animals, which occurs ubiquitously in
the environment. It is present in trace amounts in both organic and inorganic forms in marine …

The globally important nature of wetland ecosystems has led to their increased protection
and restoration as well as their use in engineered systems. Underpinning the beneficial …

The influence of redox potential and pH on arsenic speciation and solubility was studied in a
contaminated soil. Alterations in the oxidation state of arsenic, as influenced by redox …

To assess the mobilities of Pb, Cd, and Zn from a contaminated soil, the effects of redox
potential and pH value on metal solubilities were investigated. Both redox potential and pH …

Oxyanions of arsenic and selenium can be used in microbial anaerobic respiration as
terminal electron acceptors. The detection of arsenate and selenate respiring bacteria in …

Many suboxic sediments and soils contain an Fe (II, III) oxide called green rust.
Spectroscopic evidence showed that selenium reduces from an oxidation state of+ VI to 0 in …

Selenium (Se) is an essential micronutrient for animal and humans; however, its essentiality
in plants is yet to be established. Nevertheless, its beneficial role is reported in crop plants …

Suboptimal dietary Se intake is widespread in Malawi due to low levels of plant-available Se
in most soils and narrow food choices. The aim of this study was to determine the potential …
