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.
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.
Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher.
Scientists from Leicester and Nottingham have devised a method for identifying levels of exposure to environmental arsenic - by testing toenail clippings.
How about the fact that even if you choose to smoke outside of your home or only smoke in your home when your children are not there - thinking that you're keeping them away from second-hand smoke - you're still exposing them to toxins?
Dioxins, environmental pollutants resulting from the production and combustion of chlorinated compounds, have been linked to an increase in ischemic heart disease (IHD) and cardiovascular disease (CVD) mortality rates, as reported in a review article in the November 2008 issue of the peer-reviewed journal Environmental Health Perspectives (EHP).
A EU-India consortium led by Queen's University Belfast has led to the development of technology which could provide safe drinking water for over 70 million people in South East Asia. The joint collaboration has resulted in the world's first low-cost technology to provide arsenic-free water to people in India and surrounding countries.
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
Alternative medicine is in the news again with scientists in the U.S. saying they have found high levels of toxic metals in popular herbal medicines sold online.
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.
