OsHAC1;1 and OsHAC1;2 Function as Arsenate Reductases and Regulate Arsenic Accumulation1 [PDF]
Plant Physiology, 2016 Rice is a major dietary source of the toxic metalloid arsenic (As). Reducing its accumulation in rice (Oryza sativa) grain is of critical importance to food safety. Rice roots take up arsenate and arsenite depending on the prevailing soil conditions. The

The Pho4 transcription factor mediates the response to arsenate and arsenite in Candida albicans
Frontiers in Microbiology, 2015 Arsenate (As (V)) is the dominant form of the toxic metalloid arsenic (As). Microorganisms have consequently developed mechanisms to detoxify and tolerate this kind of compounds.

Arsenate resistance in the unicellular marine diazotroph Crocosphaera watsonii [PDF]
Frontiers in Microbiology, 2011 The toxic arsenate ion can behave as a phosphate analog, and this can result in arsenate toxicity especially in areas with elevated arsenate to phosphate ratios like the surface waters of the ocean gyres.

Phosphate Transporters Mediate the Uptake of Monothioarsenate. [PDF]
Plant Cell EnvironABSTRACT Arsenic (As) is one of the most problematic environmental toxins. Exposure to As, predominantly via drinking water and the intake of food, represents a major human health threat. Various species of As exist in the environment, among them organic and inorganic thioarsenates.

DC-magnetometry Analytical Tool Driven by Spin Ordering Phenomena for Sensing Chemical Interactions at the Surface of Nanomaterials. [PDF]
Adv Sci (Weinh)The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

Phosphate competition with arsenate on poorly crystalline iron and aluminum (hydr)oxide mixtures.
Chemosphere, 2020 Phosphate competes with arsenate for sorption sites on poorly crystalline iron and aluminum (hydr)oxides. The competition has implications e.g. for the management of arsenic-contaminated soil and water. Phosphate competition with arsenate on mixed phases

CA: A Cancer Journal for Clinicians, 2001 The toxicity and carcinogenicity of arsenic are well known, but vexing questions remain. The current controversy over the appropriate Federal limit for arsenic in drinking water highlights some of the difficult scientific, ethical, economic, and political issues that complicate standard-setting in occupational and environmental health.

An arsenic metallochaperone for an arsenic detoxification pump [PDF]
Proceedings of the National Academy of Sciences, 2006 Environmental arsenic is a world-wide health issue, making it imperative for us to understand mechanisms of metalloid uptake and detoxification. The predominant intracellular form is the highly mephitic arsenite, which is detoxified by removal from cytosol.
