Arsenic is a naturally occurring element widely distributed in the earth’s crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.
Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small “corns” or “warts” on the palms, soles, and torso.
While exposure to high concentrations of the element in drinking water and in the workplace has been shown to be associated with diabetes, little is known about the effect of lower levels on diabetes risk.
Inorganic arsenic, commonly found in ground water in certain areas, may increase the risk of developing type 2 diabetes, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.
Amid recent reports of dangerous levels of arsenic being found in some baby rice products, scientists have found a protein in plants that could help to reduce the toxic content of crops grown in environments with high levels of this poisonous metal.
In both leukemia and solid tumors, there exists among the multitude of warrior cancer cells a small subgroup that work undercover, patiently lying in wait to launch their attacks. Known as either cancer initiating cells (CICs) or leukemia initiating cells (LICs), these stealth populations are impervious to conventional chemotherapy and undaunted by targeted cancer therapies. When a leukemia patient relapses following a period of remission, it is the LICs that bear responsibility for the disease's reemergence.
In what will be of great concern to many parents, scientists who have carried out a survey of arsenic levels in three common brands of rice-based baby foods say they have found that arsenic levels in the foods are too high.
Cancer Research UK scientists have discovered how arsenic works as an effective treatment for leukaemia - according to a report in Nature Cell Biology.
Scientists in Arizona report that minerals from clay could form the basis of a new generation of inexpensive, highly-effective antimicrobials for fighting MRSA infections that are moving out of health care settings and into the community.
What the recent story about traces of pharmaceuticals in our drinking water makes very clear is that access to safe drinking water is an issue that affects everyone.
Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found.

A risk assessment tool has been developed through the Cancer Control Program at South Eastern Sydney & Illawarra Health (SESIH) by a University of New South Wales (UNSW) researcher, Professor Bernard Stewart.
New research has allayed some panic about suspected cancer-causing agents, such as deodorants, coffee and artificial sweeteners. A risk assessment tool has been developed through the Cancer Control Program at South Eastern Sydney & Illawarra Health (SESIH) by a University of New South Wales (UNSW) researcher, Professor Bernard Stewart.
Though a worldwide problem, arsenic contamination of drinking water does not have a universal solution.
The doctor, Dr. Roy Kerry of Portersville, Butler County, has been charged with manslaughter after incorrectly administering a controversial chemical treatment.
A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. The finding is further evidence that arsenic at low doses (at levels found in U.S. drinking water in some areas) can be harmful.
Changes in gene expression patterns in zebrafish embryos resulting from exposure to environmental toxins can identify the individual toxins at work, according to research published in the online open access journal Genome Biology.
Bangladeshi women exposed to high levels of arsenic during pregnancy are at increased risk of having a low-birth-weight infant, reports a study in the October Journal of Occupational and Environmental Medicine , official publication of the American College of Occupational and Environmental Medicine (ACOEM).
A new study conducted in Bangladesh finds that folic acid supplements can dramatically lower blood arsenic levels in individuals chronically exposed to arsenic-contaminated drinking water.
A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water.
Cephalon, Inc. announced today that the U.S. Food and Drug Administration (FDA) Office of Orphan Products Development granted orphan drug designation for the company's investigational therapy, TREANDA (bendamustine HCl), for the treatment of chronic lymphocytic leukemia (CLL).
