Advances in science and nanotechnology have facilitated the development of new methods
for the preparation of pure selenium as selenium nanomaterials. They offer remarkable …

Selenium is an essential trace element that has raised interest because of its antioxidant
and anticancer properties. The beneficial or toxic effect of Se is not only dose-dependent …

Abstract Background Selenium (Se) in soil mainly consists of selenite, selenate, and
elemental Se. However, little is known about the mechanism involved in the uptake and …

Rice is an important source of essential elements. However, rice may also contain toxic
elements such as arsenic. Therefore, in the present study, the concentration of total arsenic …

Extraction has been used probably since the discovery of fire. Egyptians and Phoenicians,

Selenium (Se) is an essential dietary trace element participating in the regulation of various
physiological functions in humans, farm animals and poultry through its incorporation into a …

Rice (Oryza sativa) is the staple food for half of the world's population, but the selenium (Se)
concentrations in rice grain are low in many rice-growing regions. This study investigated …

Extraction using 0.28 M nitric acid at 95° C for 90 min recovers not only arsenic quantitatively
from rice grains independent of types but also preserves arsenic speciation completely. It is …

Inorganic arsenic (iAs) is a contaminant present in food, especially in rice and rice-based
products. Toxicity of arsenic compounds (As) depends on species and oxidative state. iAs …
