Exposure to inorganic arsenic in contaminated drinking water poses an environmental public health threat for hundreds of millions of people in the US and around the world. Arsenic is a known carcinogen for skin cancer. However, the mechanism by which arsenic induces skin cancer remains poorly understood. Here, we have shown that arsenic induces p62 expression in an autophagy-independent manner ...

Determination of oxidation states of solid-phase arsenic in bulk sediments is a valuable step in the evaluation of its bioavailability and environmental fate in deposits, but is difficult when the sediments have low arsenic contents and heterogeneous distribution of arsenic species. As K-edge X-ray absorption near-edge spectroscopy (XANES) was used to determine quantitatively the oxidation stat...

BACKGROUND Limited data exist on the contribution of dietary sources of arsenic to an individual's total exposure, particularly in populations with exposure via drinking water. Here, the association between diet and toenail arsenic concentrations (a long-term biomarker of exposure) was evaluated for individuals with measured household tap water arsenic. Foods known to be high in arsenic, includ...

The behavior of arsenic during pyrolysis at temperatures between 135 and 500 degrees C has been widely studied. We examined the release of arsenic during the pyrolysis of chromated copper arsenate (CCA)-treated wood, and here we propose two models for the volatilization of arsenic: (a) a reacted arsenic compound, chromium arsenate, in CCA-treated wood was initially decomposed to arsenic pentoxi...

Soil contamination with heavy metals such as arsenic has harmful effects on human health and agricultural products. Arsenic (AS) is one of the heavy metals which are highly toxic and carcinogenic. This research was conducted to study the effect of organic manure on increasing the Arsenic absorption ability by Cress plant in the greenhouse of the Agriculture and Natural Resources Research Center...

In an area near an arsenic mine in Hunan Province of south China, soils were often found with elevated arsenic levels. A field survey was conducted to determine arsenic accumulation in 8 Cretan brake ferns (Pteris cretica) and 16 Chinese brake ferns (Pteris vittata) growing on these soils. Three factors were evaluated: arsenic concentration in above ground parts (fronds), arsenic bioaccumulatio...

Arsenic trioxide has been successfully used as a therapeutic in the treatment of acute promyelocytic leukemia (APL). Detailed monitoring of the therapeutic arsenic and its metabolites in various accessible specimens of APL patients can contribute to improving treatment efficacy and minimizing arsenic-induced side effects. This article focuses on the determination of arsenic species in saliva sa...

Arsenic is an environmental hazard and the reduction of drinking water arsenic levels is under consideration. People are exposed to arsenic not only through drinking water but also through arsenic-contaminated air and food. Here we report the health effects of arsenic exposure from burning high arsenic-containing coal in Guizhou, China. Coal in this region has undergone mineralization and thus ...

Long time uptake arsenic will cause cancers and blackfoot disease. There are still several million people suffering from drinking arsenic ontaminated water. This work studied the performance of coupled chitosan/UF for arsenic removal and the influence of dissolved organic matter n arsenic removal with UF operation. Humic acid representing dissolved organic matter was fractionated into five grou...
