(PhysOrg.com) -- Mention of arsenic poisoning usually brings to mind underhanded murder. However, the danger of arsenic poisoning from contaminated drinking water is far greater. Low concentrations of arsenic are found in nearly all soils and thus also in ground water. About 140 million people worldwide possibly drink water that contains arsenic concentrations above the WHO-recommended limit of 10 ppb (parts per billion). http://www.physorg.com/news178347619.html Nanotechnology Wed, 25 Nov 2009 05:02:58 EST news178347619 Biomethylation of arsenic compounds appears to cause oxidative DNA damage and to increase their carcinogenicity, according to a new study published online November 23 in the Journal of the National Cancer Institute. http://www.physorg.com/news178217854.html Medicine & Health Mon, 23 Nov 2009 17:40:04 EST news178217854 Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. The research suggests that human alteration to the landscape, the construction of villages with ponds, and the adoption of irrigated agriculture are responsible for the current pattern of arsenic concentration underground. http://www.physorg.com/news177515521.html Space & Earth Sun, 15 Nov 2009 13:52:45 EST news177515521 A Kansas State University geologist and graduate student are finding that the most important tools in their fieldwork on groundwater arsenic pollution are women and children armed with pamphlets and testing kits. http://www.physorg.com/news175430543.html Space & Earth Thu, 22 Oct 2009 12:30:04 EST news175430543 Ford Motor Co. will haul out piles of arsenic-laced soil found in Ringwood State Park in New Jersey, ending a nearly-four-year battle over the source of the waste. http://www.physorg.com/news175266009.html Space & Earth Tue, 20 Oct 2009 14:50:01 EST news175266009 If you spend an afternoon walking along the muddy shore of Mono Lake, with the eastern flank of the Sierra Nevada mountains looming majestically in the background, you`ll no doubt discover, as others have before, that it is a place of bizarre natural beauty. http://www.physorg.com/news173988321.html Biology Mon, 05 Oct 2009 19:06:19 EST news173988321 Large variations exist in peoples' ability to eliminate arsenic from the body, according to a new study that questions existing standards for evaluating the human health risks from the potentially toxic substance. The study found that some people eliminate more than 90 percent of the arsenic consumed in the diet. Others store arsenic in their bodies, where it can have harmful effects. The research, based on the first application of new methods for studying arsenic, is scheduled for the Sept. 21 issue of ACS's Chemical Research in Toxicology. http://www.physorg.com/news170503268.html Chemistry Wed, 26 Aug 2009 12:10:01 EST news170503268 Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent. http://www.physorg.com/news167412238.html Nanotechnology Wed, 22 Jul 2009 13:30:01 EST news167412238 Rice University researchers today announced that the first field tests of "nanorust," the university's revolutionary, low-cost technology for removing arsenic from drinking water, will begin later this year in Guanajuato, Mexico. http://www.physorg.com/news162642319.html Nanotechnology Wed, 27 May 2009 11:26:02 EST news162642319 The ability to mount an immune response to influenza A (H1N1) infection is significantly compromised by a low level of arsenic exposure that commonly occurs through drinking contaminated well water, scientists at the Marine Biological Laboratory (MBL) and Dartmouth Medical School have found. http://www.physorg.com/news162048605.html Medicine & Health Wed, 20 May 2009 14:33:54 EST news162048605 (PhysOrg.com) -- Every day, more than 140 million people in southern Asia drink groundwater contaminated with arsenic. Thousands of people in Bangladesh, Cambodia, India, Myanmar and Vietnam die of cancer each year from chronic exposure to arsenic, according to the World Health Organization. Some health experts call it the biggest mass poisoning in history. http://www.physorg.com/news157133188.html Space & Earth Tue, 24 Mar 2009 17:09:14 EST news157133188 Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. http://www.physorg.com/news155841706.html Space & Earth Mon, 09 Mar 2009 18:22:22 EST news155841706 (PhysOrg.com) -- Scientists from Leicester and Nottingham have devised a method for identifying levels of exposure to environmental arsenic - by testing toenail clippings. http://www.physorg.com/news154342897.html Space & Earth Mon, 23 Feb 2009 03:50:01 EST news154342897 When mice are exposed to arsenic at federally-approved levels for drinking water, pores in liver blood vessels close, potentially leading to cardiovascular disease, say University of Pittsburgh researchers in the Dec. 1 issue of the Journal of Clinical Investigation, available online Nov. 13. The study, while preliminary, also reveals how an enzyme linked to hypertension and atherosclerosis alters cells, and may call into question current Environmental Protection Agency standards that are based solely on risks for cancer. http://www.physorg.com/news145818421.html Medicine & Health Thu, 13 Nov 2008 17:07:01 EST news145818421 A simulated gastrointestinal system is helping scientists test contaminated soil for its potential to harm humans.
