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.
Mailman School of Public Health study provides evidence that a population exposed to well water with arsenic concentrations of as little as 50 ug/l is at risk for skin lesions.
Dartmouth researchers, working with scientists at the University of Arizona and at the Department of Natural Resources in Sonora, Mexico, have published a study on the impact of arsenic exposure on DNA damage.
Children who are exposed to high levels of arsenic in their drinking water are seven to 12 times more likely to die of lung cancer and other lung diseases in young adulthood, a new study by University of California, Berkeley, and Chilean researchers suggests.
Up to two-thirds of all cancers may be prevented through dietary and lifestyle changes. In the case of skin cancer, this could not be more true.
Exposure to toxic elements leads to worrying health problems in many parts of the world, including Europe.
Tobacco smoke in enclosed spaces is not simply a nuisance: it is a threat to health with fatal consequences. This is the conclusion reached by the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) in its latest publication.
The floodwaters that inundated New Orleans immediately following Hurricane Katrina were similar in content to the city’s normal storm water and were not as toxic as previously thought, according to a study by researchers at Louisiana State University.
Multi-vitamin products, nutritional supplements and parents tout the need for such mineral elements as calcium, zinc, phosphorus, iron and others.
According to new research by the National Health Service (NHS), 60 per cent of smokers light up and smoke without asking for permission, despite the fact that most non-smokers mind if other people are smoking nearby.
Oxford scientists have contributed to the genome sequencing of two parasites which cause major health problems in the developing world.
According to Swissmedic, the Swiss Agency for Therapeutic Products, the NicStic is not a medicinal product and the way has been cleared for its commercial production.
According to a newly released study, high concentrations of arsenic have been found in a sample of King George III's hair, and this, say the authors, may have contributed to his unusually severe and prolonged bouts of madness.
A study revealing high concentrations of arsenic in a sample of King George III’s hair is published in this week’s issue of The Lancet. The authors believe the presence of arsenic in the King’s hair contributed to his unusually severe and prolonged bouts of madness.
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.
