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.
A team of soil scientists from RUDN University confirmed that traditional approaches to urban soil pollution monitoring ignore actual risks for urban residents because they don't take into consideration the barrier function of the soil.
Much of life on planet Earth today relies on oxygen to exist, but before oxygen was present on our blue planet, lifeforms likely used arsenic instead.
Who are we? Where did we come from? How did we get here? Throughout the ages, humans have sought answers to these questions, pursuing wisdom through religion, philosophy, and eventually science.
Antibiotic resistance is an increasing health problem, but new research suggests it is not only caused by the overuse of antibiotics. It's also caused by pollution.
Rice is the most widely consumed staple food source for a large part of the world's population. It has now been confirmed that rice can contribute to prolonged low-level arsenic exposure leading to thousands of avoidable premature deaths per year.
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler.
The U.S. Department of Energy recently announced the funding of two projects with Lehigh University's Energy Research Center.
An adenovirus infection can be potentially life-threatening, especially for children after a stem cell transplant.
Scientists at Laboratory of Organic Electronics, Linköping University, have developed an organic electrochemical transistor that they can use to measure and study in fine detail a phenomenon known as extracellular electron transfer in which bacteria release electrons.
Scientists have called for labeling to warn the public about levels of arsenic in rice after research found rice varieties studied exceeded maximum limits.
Mushrooms are a protein- and mineral-rich food source, but they can also accumulate high levels of toxic metals and metalloids.
