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.
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.
A frosty mug of beer or ruby-red glass of wine just wouldn't be the same if the liquid was murky or gritty. That's why producers of alcoholic beverages usually filter them.
Viruses plague bacteria just as viruses like influenza plague humans. Some of the largest of these so-called bacteriophages have now been found in the human gut, where they periodically devastate bacteria just as seasonal outbreaks of flu lay humans low, according to a new study led by University of California, Berkeley, scientists.
A free, simple screening for lung cancer can save a patient money, while building a healthy relationship for any medical needs they may have in the future.
Research conducted at Montana State University shows that microbes in the human gut play an important role in protecting against arsenic toxicity, a problem that affects an estimated 200 million people who are exposed to arsenic through contaminated drinking water.
New findings from a team of Marshall University Joan C. Edwards School of Medicine researchers reveal urban and rural differences in prenatal exposure to essential and toxic elements.
It takes six months to get really good at accurately gauging the age of yelloweye rockfish. Because they can live for up to 120 years, this species is of particular interest to Benjamin Barst and scientists like him who study the effects of toxic chemicals on living organisms.
The European Medicines Agency's Committee for Medicinal Products for Human Use has adopted a positive scientific opinion of fexinidazole, the first all-oral treatment that has been shown to be efficacious for both stages of sleeping sickness.
Nexus Pharmaceuticals announced today the immediate availability in the United States for Arsenic Trioxide Injection. Nexus Pharmaceuticals' Arsenic Trioxide Injection is available as 10 mg per 10 mL vial for injection.
Uncovering a novel mechanism that promotes growth of breast cancer bone metastasis has revealed a potential Achilles' heel for these cancer cells. Reported in the journal Cancer Cell, the study shows that interfering with this mechanism can reduce the risk of relapses in animal models.
The MDI Biological Laboratory will take a national lead in teaching data literacy to students and teachers though a five-year, $1.2 million SEPA grant from the National Institute of General Medical Sciences, an institute of the National Institutes of Health.
