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 use of arsenic trioxide instead of idarubicin in combination with all-trans retinoic acid is a feasible option in patients with acute promyelocytic leukaemia, regardless of risk level, suggests a phase III trial.
In what is believed to be the largest, most detailed study of its kind in the United States, scientists at NYU Langone Medical Center and elsewhere have confirmed that tiny chemical particles in the air we breathe are linked to an overall increase in risk of death.
The Drugs for Neglected Diseases initiative (DNDi) has announced today at the 9th European Congress on Tropical Medicine and International Health in Basel, Switzerland, the successful completion of Phase I human clinical trials for SCYX-7158 (AN5568), the first oral drug candidate specifically developed from the earliest drug discovery stage to combat human African trypanosomiasis, or sleeping sickness, a deadly parasitic disease transmitted by the tsetse fly.
Female mice exposed in utero, or in the womb, to low levels of arsenic through drinking water displayed signs of early puberty and became obese as adults, according to scientists from the National Institutes of Health.
Arsenic, which can be present in ground water, modifies an enzyme that alters the secretion of insulin in the pancreas. Physicians, usually, show type II diabetes as a consequence of an exaggerated food intake and lack of exercise; however, there are about 50 genes that cause changes in the DNA, known as polymorphisms, that when combined with harsh environmental factors are at increased risk of developing the disease, mentioned PhD Marta Ostrosky Wegman, director of the Institute for Biomedical Research the National University of Mexico (UNAM).
A new material that mimics coral could help remove toxic heavy metals like mercury from the ocean, according to a new study published in the Journal of Colloid and Interface Science. The researchers, from Anhui Jianzhu University in China, say their new material could provide inspiration for other approaches to removing pollutants.
University of Delaware researchers have discovered a soil microbe that mobilizes an "iron shield" to block the uptake of toxic arsenic in rice.
New research suggests the use of hookah steam stones - commonly considered a safer alternative to cigarette smoking - could be leaving users with a dangerous, false sense of security. The findings out of the University of Cincinnati/Agilent Technologies Metallomics Center of the Americas are published this month in the Microchemical Journal.
The placenta can be used to reliably measure arsenic exposure in pregnant women and how much of the toxic metal is transferred to their fetuses, a Dartmouth College study shows.
Virginia Tech biochemists are trying to deliver a stern wake-up call to the parasite that causes sleeping sickness.
In the first U.S. study of urinary arsenic in babies, Dartmouth College researchers found that formula-fed infants had higher arsenic levels than breast-fed infants, and that breast milk itself contained very low arsenic concentrations.
New grants totaling $3 million will go to six outstanding early-career scientists, bridging a funding gap to independent biomedical research. The National Institute of Environmental Health Sciences, part of the National Institutes of Health, created the award to encourage early stage researchers who want to discover how our environment influences human health.
Naturally occurring arsenic in private wells threatens people in many U.S. states and parts of Canada, according to a package of a dozen scientific papers to be published next week. The studies, focused mainly on New England but applicable elsewhere, say private wells present continuing risks due to almost nonexistent regulation in most states, homeowner inaction and inadequate mitigation measures.
Researchers at UPM have studied the stability of diverse arsenic species found in edible marine algae and have established the best conditions for their storage and preservation.
Scientists from the Department of Energy's Pacific Northwest National Laboratory will present a variety of research at the 2014 American Geophysical Union Fall Meeting, which runs Monday, Dec. 15 through Friday, Dec. 19 at the Moscone Convention Center in San Francisco.
Children with autism spectrum disorder (ASD) were more likely to have been exposed to higher levels of certain air toxics during their mothers' pregnancies and the first two years of life compared to children without the condition, according to the preliminary findings of a University of Pittsburgh Graduate School of Public Health investigation of children in southwestern Pennsylvania.
Rice is one of the few cereal grains consumed by people with celiac disease, as it does not contain gluten. However, it can have high concentrations of a toxic substance – arsenic – as revealed by the analyses of flour, cakes, bread, pasta and other foods made with rice, conducted by researchers from the Miguel Hernández University of Elche, Spain.
Associated with various types of cancer such as skin and liver, the intake of arsenic it is also linked to cardiovascular disease and diabetes. According to a long-term research conducted by experts from the Center for Research and Advanced Studies it was determined that this metalloid inhibits enzymes associated with antioxidant protection.
Arsenic poisoning is widespread in Bangladesh, where ground water is contaminated by runoff from the Himalayas.
Yogurt containing probiotic bacteria successfully protected children and pregnant women against heavy metal exposure in a recent study.
