Geoscientists follow arsenic from chicken feed to streambeds
What happened to the chicken when she crossed the road is less important that what happens to what she eats when it is used as fertilizer. Organic arsenic is fed to poultry to prevent bacterial infections and improve weight gain. A little bit of arsenic is taken up by the tissue and the majority of it is excreted in urine. Poultry litter -- the wood chips, feathers, droppings, and urine fr...Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy
Environmental arsenic pollution is a serious and growing environmental problem, especially on the Indian subcontinent. Researchers at the University of Georgia had, several years ago, used genetic techniques to create "arsenic-eating" plants that could be planted on polluted sites. There was a problem, however. The arsenic sequestered from soil remained largely in the roots of the plant, m...Dartmouth study finds that arsenic inhibits DNA repair
Dartmouth researchers, working with scientists at the University of Arizona and at the Department of Natural Resources in Sonora, Mexico, have published a study on the impact of arsenic exposure on DNA damage. They have determined that arsenic in drinking water is associated with a decrease in the body's ability to repair its DNA. "This work supports the idea that arsenic in drinking wate...Arsenic in chicken feed may pose health risks to humans, C&EN reports
Pets may not be the only organisms endangered by some food additives. An arsenic-based additive used in chicken feed may pose health risks to humans who eat meat from chickens that are raised on the feed, according to an article in the April 9 issue of Chemical & Engineering News, the weekly news magazine of the American Chemical Society. Roxarsone, the most common arsenic-based addit...Speciation of Arsenic by LC-ICP-MS
As toxicity, mobility, and bioavailability can differ greatly between the various chemical species in which an element occurs, reporting only the total concentrations can often be misleading. Arsenic is o...Drinking arsenic water leads to cancer
According to a press release about one third the population of Bangladesh are at risk of getting cancer from arsenic deposits in well water. Drinking arsenic tainted water for prolonged periods results in skin lesions and cancer of kidney, skin, lung and bladder said the study.// At least 100,000 cases of debilitating skin lesions have already occurred, according to World Hea...Chickens Found To Have High Levels of Arsenic
People in the United States have steadily increased their consumption of chicken from 32 pounds a year per person // in 1966 to 81 pounds per person in 2000. A new study shows young chickens have significant higher levels of arsenic than other poultry or meat. Arsenic is an approved animal feed supplement that farmers use to control intestinal parasites in chickens. Researchers from...Arsenic poisoning reactions can be traced to genes
The reaction to a common water pollutant called arsenic may not be the same in all people. Researchers have // pointed out to a gene called CYT19 in people, particularly in children, that may be responsible for varied reactions to the metal called arsenic. Arsenic exposure had long been associated with health hazards like cancer of the skin, lungs or bladder, circulatory problems, and...Arsenic May Have Been Responsible For The Madness Of King George III Of England
An interesting study from hair of King George III reveals that he may// have been consuming Arsenic and this lead to his unusually severe and prolonged bouts of madness. Lancet has published this report this week and at last has been able to throw light on the reason for the madness of the famous English King George III. The study reports to have found high concentrations of arsenic...
