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.

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).

For the first time, researchers have been able to show that mothers who drink water containing arsenic run an increased risk of having a miscarriage or losing their child in its first year. This has been demonstrated by a research team from Sweden and Bangladesh in an article published last Saturday in the Net edition of American Journal of Epidemiology.
The Food and Drug Administration (FDA) is warning consumers not to drink certain brands of mineral water imported from Armenia due to the risk of exposure to arsenic, a toxic substance and known cause of cancer in humans.
New research shows that a recently discovered enzyme that destroys the messenger RNA (mRNA) for some proteins can also help to protect the mRNA during times of stress. The response might help cancer cells survive chemotherapy and radiation therapy.
