The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up
by the cells of the plant root. Once in the cell, AsV can be readily converted to AsIII, the more …

Arsenic (As) is a non-essential toxic metalloid whose elevated concentration in rice grains is
a serious issue both for rice yield and quality, and for human health. The rice-As interactions …

Rice is a major source of inorganic arsenic (iAs) in the human diet because paddy rice is
efficient at accumulating As. Rice As speciation is dominated by iAs and dimethylarsinic acid …

Methylated arsenic (As) species are a common constituent of rice grains accounting for 10–
90% of the total As. Recent studies have shown that higher plants are unlikely to methylate …

A global data analysis shows that rice grain arsenic (As) concentrations increase with
increasing soil As concentrations until about 60 mg As kg− 1 soil and then decreases. Of the …

Iron (Fe)-based solids can reduce arsenic (As) mobility and bioavailability in soils, which has
been well recognized. However, to our knowledge, there are few studies on As uptake at …

Arsenic (As) elevation in paddy soils will have a negative impact on both the yield and grain
quality of rice (Oryza sativa L.). The mechanistic understanding of As uptake, translocation …

Arsenic (As) contamination of rice (Oryza sativa) is a worldwide concern and elucidating the
molecular mechanisms of As accumulation in rice may provide promising solutions to the …

Agroecological zones within Bangladesh with low levels of arsenic in groundwater and soils
produce rice that is high in arsenic with respect to other producing regions of the globe. Little …

Strategies to reduce arsenic (As) in rice grain, below concentrations that represent a serious
human health concern, require that the mechanisms of As accumulation within grain be …
