Arsenic News and Research

RSS

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.

Fungus used in traditional medicine could slow neuron loss in ALS

New research could help design algae that produces fuels and cleanup chemicals

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.

Exposure to airborne metal pollutants linked with greater risk of mortality

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 contaminated with arsenic may lead to changes in heart structure

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.

UA researchers are developing new method to make drinking water safer

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.

Pollutants appear to weaken immune system and increase pathogen virulence

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.

$2.7 million grant supports UIC researchers to study role of arsenic in development of diabetes

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.

Material used to filter beer and wine could transfer heavy metals to it

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.

Megaphages detected in the intestinal tract of humans who eat high-fiber, low-fat diet

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.

Mercury is not well detoxified by yelloweye rockfish, researchers find

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.
