Relation of dietary inorganic arsenic exposure and urinary inorganic arsenic metabolites excretion in Japanese subjects

Journal of Environmental Science and Health, Part B, 2017
Inorganic arsenic (InAs) is a ubiquitous metalloid that has been shown to exert multiple adverse health outcomes. Urinary InAs and its metabolite concentration has been used as a biomarker of arsenic (As) exposure in some epidemiological studies, however, quantitative relationship between daily InAs exposure and urinary InAs metabolites concentration ...

Chemistry of inorganic arsenic in soils: kinetics of arsenic adsorption–desorption

Environmental Geochemistry and Health, 2008
The influence of ionic strength, index cations and competing anions on arsenate (As(V)) adsorption-desorption kinetics was studied in an Alfisol soil. A flow-through reactor system similar to that developed by Carski and Sparks (Soil Sci Soc Am J 49:1114-1116, 1985) was constructed for the experiments.

Arsenic excretion by monkeys dosed with arsenic-containing fish or with inorganic arsenic

Bulletin of Environmental Contamination and Toxicology, 1978
Four 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.

Preservation of Inorganic Arsenic Species in Groundwater

Environmental Science & Technology, 2005
The objective of this research was to develop a robust preservation method for stabilizing inorganic As(IlI/V) species in synthetic and actual groundwaters. Ethylenediaminetetraacetic acid (EDTA), H2SO4, H3PO4, and EDTA-acetic acid (HAc) were evaluated in synthetic groundwater containing 3 mg/L Fe(ll) in the pH range 6.5-8.4 and Eh range -100 to +200 ...

Maritime Deposition of Organic and Inorganic Arsenic

Environmental Science & Technology, 2019
The speciation of arsenic in wet and dry deposition are ambiguously described in current literature. Presented here is a 2 year study quantifying arsenic species in atmospheric deposition collected daily from an E. Atlantic coastal, semirural site, with comparative urban locations.

Total and Inorganic Arsenic in Iranian Rice

Journal of Food Science, 2015
Abstract It is well known that arsenic (As) exposure, particularly to inorganic species (i‐As), has adverse effects on humans. Nowadays, the European Union (EU) has still not regulated the maximum residue limit of As in commercial samples of rice and rice‐based products, although it is actively working on the topic.

Carcinogenic risks of inorganic arsenic in perspective

International Archives of Occupational and Environmental Health, 1996
Induction of cancer by inorganic arsenic occurs inconsistently between species and between routes of exposure, and it exhibits different dose-response relationships between different target organs. Inhaled or ingested arsenic causes cancer in humans but not in other species.

Inorganic Arsenic Metabolism in Man

1982
The human organism can cope with moderate doses of inorganic arsenic by a rapid and efficient methylation process giving monomethylated arsonic and dimethylated arsinic acids which are rapidly eliminated in the urine along with untransformed inorganic arsenic.

Human carcinogenicity of inorganic arsenic

1997
Arsenic is widely distributed in nature and mainly transported in the envi ronment by water. All humans are exposed to low levels of arsenic through air, drinking-water, food and beverages. Cigarette smokers may be exposed to arsenic in tobacco, but the chemical form of arsenic in the smoke remains unclear. For most people, food constitutes the largest

Inorganic arsenic toxicosis in cattle.

Modern veterinary practice, 1981
In 4 occurrences of arsenic poisoning in cattle, the principal clinical sign was acute hemorrhagic diarrhea attributable to hemorrhagic gastroenteritis. Arsenic concentrations in the liver, kidney and rumen contents varied. In one occurrence, arsenic in the hair of affected survivors was assayed at 0.8-3.40 ppm, vs 0.09-0.10 ppm in randomly selected ...
