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.
Leatherback turtle (Dermochelys coriacea) eggs laid in Bocas del Toro nesting beaches in the Panamanian Caribbean may be harmful to consumers.
The MDI Biological Laboratory has announced that it is expanding its innovative SEPA (Science Education Partnership Award) program, which aims to improve secondary school education in data literacy while addressing the public health threat posed by arsenic in well water.
People around the world consume rice in their daily diets. But in addition to its nutrient and caloric content, rice can contain small amounts of arsenic, which in large doses is a toxin linked to multiple health conditions and dietary-related cancers.
For more than a decade, Raymond Ho has answered calls for California's poison emergency hotline.
There is no clear link between cancer incidence and locally produced food from an area with a history of glass manufacture with contaminated soil, according to a new study from, among others, Linköping University in Sweden.
Tap water contaminated with a toxic cocktail of chemical pollutants could be responsible for more than 100,000 cancer cases in the US over a lifetime.
A Chinese caterpillar fungus that is used in traditional Chinese medicine has been found to minimize motor neuron loss in mice models of ALS.
It's a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a study in the journal eLife.
A mother is calling on the health industry to regulate sales of protein powder and supplements after her daughter died in 2017 due to a protein-heavy diet.
Although there is ample evidence that air pollution--specifically airborne particulate matter--is associated with an increased risk of premature death, it is still not known which specific particles are responsible for this effect.
Drinking water that is contaminated with arsenic may lead to thickening of the heart's main pumping chamber in young adults, according to a new study by researchers at Columbia University Mailman School of Public Health.
Filled with a noxious brew of copper, cadmium and arsenic, with a pH rivaling that of sulfuric acid, Montana's Berkeley Pit seems inhospitable to life.
In what has been called "the largest mass poisoning of a population in history," some 40 million people in Bangladesh are drinking water that contains unsafe levels of arsenic.
Drinking water that is contaminated with arsenic may lead to thickening of the heart's main pumping chamber in young adults, a structural change that increases the risk for future heart problems, according to new research in Circulation: Cardiovascular Imaging, an American Heart Association journal.
Antibiotic resistance has been called one of the biggest public health threats of our time. There is a pressing need for new and novel antibiotics to combat the rise in antibiotic-resistant bacteria worldwide.
Life scientists from UCLA and the University of Bern have identified a key gene in the transmission of African sleeping sickness -- a severe disease transmitted by the bite of infected tsetse flies, which are common in sub-Saharan Africa.
A smartphone device could help millions of people avoid drinking water contaminated by arsenic.
For decades, manmade chemicals known as per- and polyfluoroalkyl substances, or PFAS, were used in everything from carpets to frying pans to firefighting chemicals for their ability to repel water and oil.
Many people view pollutants and pathogens as separate causes of illness. However, recent research indicates that the two can interact, changing how people and animals respond to infectious diseases.
A five-year, $2.7 million grant from the National Institute of Environmental Health Sciences will help researchers at the University of Illinois at Chicago answer basic questions about the role of arsenic in the development of diabetes and examine the mechanisms by which selenoproteins – found in the human body in 25 different forms – counter the effects of arsenic.
