The article considers the classification of organoarsenic compounds and types their production; application computer simulation in chemical-technological processes. reaction for obtaining sodium 2-oxido(phenyl)arsoryl acetate was simulated, kinetic curves were obtained analyzed; parameters are set to increase yield product

Although epidemiological evidence shows an association between arsenic in drinking water and increased risk of skin, lung, and bladder cancers, arsenic compounds are not animal carcinogens. The lack of animal models has hindered mechanistic studies of arsenic carcinogenesis. Previously, this laboratory found that low concentrations of arsenite (the likely environmental carcinogen) which are not...

Size-reduced samples of southern yellow pine dimensional lumber, each treated with one of five different waterborne chemical preservatives, were leached using 18-h batch leaching tests. The wood preservatives included chromated copper arsenate (CCA), alkaline copper quaternary, copper boron azole, copper citrate, and copper dimethyldithiocarbamate. An unpreserved wood sample was tested as well....

Arsenic is an environmentally ubiquitous health hazard due to its toxicity combined with natural abundance and heavy industrial applications. Due role in cardiovascular disease, neurotoxicity, various cancers, it important understand environmental fate of arsenic-containing compounds take steps towards remediation. Sodium arsenite (NaAsO2) one such compound that has been used worldwide as herbi...

Humans are exposed to arsenic (As) in the environment, in both organic and inorganic forms, and it has been widely demonstrated that the inorganic arsenic species (arsenate and arsenite) are the main toxic ones being drinking water one of the main sources of exposure worldwide. Urinary arsenic level is the recommended biomarker for assessing human exposure risks. Absorbed inorganic arsenic is m...

Metals and metal compounds have been used in medicine for several thousands of years. In this review we summarized the anti-cancer activities of the ten most active metals: arsenic, antimony, bismuth, gold, vanadium, iron, rhodium, titanium, gallium and platinum. The first reviewed metal, arsenic, presents the anomaly of displaying anti-cancer and oncogenic properties simultaneously. Some antim...

(Neuro-)toxicity of metal and metal compounds is frequently highlighted. While specific metals or metal compounds are essential for cellular function, other metals are toxic and/or carcinogens. Metals can trigger accidental cell death in the form of necrosis, or activate programmed cell death in the form of apoptosis. The aim of anti-cancer therapy is induction of apoptosis in tumor cells. Ther...

festival in Wakayama prefecture, Japan, was laced with an arsenic compound. In the following month, a case was reported in Niigata prefecture in which sodium azide was added to a pot of tea. Subsequently, there was a series of cases involving the poisoning of tea or fruit juice across Japan, which caused health problems in many citizens and were fatal to others. The Japanese Ministry of Health,...
