Fate of arsenicals in different environmental substrates.
The current knowledge of arsenic (As) transformations in the environment, as well as some gaps in this knowledge, are reviewed. These transformations involve As chemical and biochemical transformations in air, waters, sediments, and soils. Arsenic moves in a dispersive manner through air and water and is in physical and chemical equilibrium in many substrates. It is oxidized, reduced, methylate...
متن کاملImpact of Trivalent Arsenicals on Selenoprotein Synthesis
BACKGROUND Exposure to arsenic has been associated with development of skin, lung, bladder, liver, and kidney cancer. Recent evidence suggests that an increase in oxidative stress in cells treated with arsenicals represents the molecular mechanism behind arsenic-induced carcinogenesis. Selenium, in the form of selenocysteine, is necessary for the activity of several enzymes with a role in defen...
متن کاملBiosensors for Inorganic and Organic Arsenicals
Arsenic is a natural environmental contaminant to which humans are routinely exposed and is strongly associated with human health problems, including cancer, cardiovascular and neurological diseases. To date, a number of biosensors for the detection of arsenic involving the coupling of biological engineering and electrochemical techniques has been developed. The properties of whole-cell bacteri...
متن کاملEffects of organic arsenicals on enzyme systems.
Investigations have been carried out by us in the Biochemical Laboratory of the Cardiff City Mental Hospital during 1938, 1939 and early 1940 on the effects of organic trivalent and pentavalent arsenic compounds on proteins and enzymes. The work was primarily undertaken to elucidate the biochemical basis of the trypanocidal and anti-spirochaetal action of a variety of organic arsenic compounds ...
متن کاملNotes on Some Remedies. XVI. Arsenicals in Non-Syphilitic Diseases
1. Anthrax.?Anti-anthrax serum is an effective remedy in this condition, but when this is not available, full doses of NAB should be administered and repeated in a day or two if there is no response as shown by abatement of the local oedema. Arsenic may also be given as supplementary to serum, indeed such a combination appears to give better results and is desirable in severe cases, especially ...
