Rapid Reduction of Arsenate in the Medium Mediated by Plant Roots [PDF]
New Phytologist, 2007 Microbes detoxify arsenate by reduction and efflux of arsenite. Plants have a high capacity to reduce arsenate, but arsenic efflux has not been reported. Tomato (Lycopersicon esculentum) and rice (Oryza sativa) were grown hydroponically and supplied with

Two New Arsenate/Sulfate-Reducing Bacteria: Mechanisms of Arsenate Reduction
Archives of Microbiology, 2000 Two sulfate-reducing bacteria, which also reduce arsenate, were isolated; both organisms oxidized lactate incompletely to acetate. When using lactate as the electron donor, one of these organisms, Desulfomicrobium strain Ben-RB, rapidly reduced (doubling

Mechanisms of Arsenate Tolerance in Cytisus striatus
New Phytologist, 2003 Arsenate tolerance, uptake and arsenate-induced phytochelatin (PC) accumulation were compared at different phosphorus supply rates in two populations of the broom, Cytisus striatus, one from an arsenic-enriched gold mine and one from a nonmetalliferous ...

New Phytologist, 1991 Uptake, translocation and accumulation of arsenate was determined in arsenate‐tolerant and non‐tolerant genotypes of Holcus lanatus L. Over a 6 h period of growth in 005 mol m−3arsenate, non‐tolerant genotypes accumulated arsenate to a much greater ...

The Determination of Arsenic in Official Arsenicals*†
Journal of the American Pharmaceutical Association (Scientific ed.), 1947Abstract An assay for the determination of arsenic is presented which is applicable to six of the seven Pharmacopoeial arsenicals. The method employs an alkali‐acid permanganate oxidation for the destruction of organic matter.

Arbuscular Mycorrhizal Fungi Confer Enhanced Arsenate Resistance on Holcus lanatus
New Phytologist, 2002 The role of arbuscular mycorrhizal fungi (AMF) in arsenate resistance in arbuscular mycorrhizal associations is investigated here for two Glomus spp. isolated from the arsenate-resistant grass Holcus lanatus.

Arsenate detoxification in a Pseudomonad hypertolerant to arsenic
Archives of Microbiology, 2006Pseudomonas sp. strain As-1, obtained from an electroplating industrial effluent, was capable of growing aerobically in growth medium supplemented with up to 65 mM arsenate (As (V)), significantly higher concentrations than those tolerated by other reference arsenic resistant bacteria. The majority of the arsenic was detected in culture supernatants as

Arsenic excretion by monkeys dosed with arsenic-containing fish or with inorganic arsenic
Bulletin of Environmental Contamination and Toxicology, 1978Four adult female Cynomolagus monkeys were given single oral dose of fish arsenic. 67% of the arsenic was excreted with the urine and 10% with the feces, essentially within 5 days post exposure. The same monkeys were later dosed with inorganic arsenic and 76% of it was excreted with the urine, and practically nil with the feces.

Arsenic poisoning continues to require awareness of its diverse clinical manifestations. Industry is the major source of arsenic exposure. Although epidemiologic studies strongly contend that arsenic is carcinogenic, there are little supportive research data.
