Inorganic arsenic (iAs) is ubiquitous in the environment as arsenite (AsIII) and arsenate
(AsV) compounds and biotransformation of these toxic chemicals leads to the extraordinary …

Element specificity is one of the key factors underlying the widespread use and acceptance
of X-ray absorption spectroscopy (XAS) as a research tool in the environmental and geo …

To maintain cellular homeostasis, concentrations, chemical speciation, and localization of
mineral nutrients and toxic trace elements need to be regulated. Imaging the cellular and …

Arsenic decreases rice yield, and inorganic grain As threatens human health; thus,
strategies to decrease rice As are critically needed. Increased plant-available silica (Si) can …

The toxicity of arsenic greatly depends on its chemical form and oxidation state (speciation)
and therefore accurate determination of arsenic speciation is a crucial step in understanding …

Increasing plant-availability of Si through soil amendment of Si-rich rice residues can
decrease inorganic As without affecting Cd levels in grain under flooded soil conditions …

Because of the toxicity of inorganic arsenic (iAs), only iAs needs to be monitored in food and
feedstuff. This demands the development of easy and quick analytical methods to screen …

Arsenic is ubiquitous in nature appearing in various chemical forms. The toxicity,
environmental mobility and accumulation of As in living organisms depends on the form in …

The human health risk associated with arsenic in food in Southeast Brazil was quantified.
Based on the most commonly consumed food types in the Brazilian diet, the maximum …

While root Si transporters play a role in the uptake of arsenite and organic As species
dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA) in rice (Oryza sativa L.), the …
