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.
Children with a particular variation in the CYT19 gene metabolize arsenic differently than adults with the same genetic variant, according to a new research report. The findings have important implications for the safety of drinking water worldwide and the use of arsenic as a cancer drug.
Residents of Taiwan who consumed drinking water with high levels of arsenic have a higher risk of lung cancer, with cigarette smokers from this group having an even greater risk, according to a study in the December 22/29 issue of JAMA.
At the 46th Annual Meeting of the American Society of Hematology (ASH) preliminary data were presented from a phase II study of Trisenox (arsenic trioxide) injection in myelodysplasia (MDS).
Researchers at UT Southwestern Medical Center at Dallas have identified a protein that transports the essential nutrient boron into cells, where it is important for cell growth and bone development. The findings are in the Nov. 5 edition of the journal Molecular Cell and are online.
The National Cancer Institute has awarded the Arizona Cancer Center at the University of Arizona Health Sciences Center a three-year grant to evaluate associations between elevated arsenic exposure and cancer incidence in Arizona and Mexico.
Arsenic trioxide – a highly poisonous substance best known as an effective weed killer or pesticide and notorious for being a favourite ‘weapon’ of choice in murder mystery novels, is being re-invented as a treatment for a rare type of leukaemia.
Arsenic could be toxic at much lower levels than previously thought, suggesting that the new EPA drinking water standard of 10 parts per billion might still be too high, according to a team of researchers at Dartmouth Medical School.
Ensuring drinking water is safe is a challenge in every part of the world, from water piped into people's homes, to rural wells and water provided to refugee camps in an emergency.
A recent study of children exposed to arsenic-tainted water in Araihazar, Bangladesh found that water arsenic was significantly associated with reduced intellectual function.
The Food Standards Agency is advising people not to eat a type of seaweed called hijiki because of the high levels of arsenic that it contains.
Exposure to secondhand smoke is even more dangerous than previously thought and increases the risk of heart disease among non-smokers by as much as 60 percent.
Researcher Kevin McElwee -- one of only a few people in the world who hold a doctoral degree in hair biology -- thinks a cure for baldness that uses the technique of hair cloning could be commercially available within 10 years.
The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) today announced the publication of a final Public Health Goal (PHG) for arsenic in drinking water.
Bladder cancer is the fourth most common cancer in men and the eighth most common in women, according to the National Cancer Institute (NCI). It is expected to be diagnosed in 38,000 men and 15,000 women in the United States in 2003. Treatment is most successful when the disease is caught early.
