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.
Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area.
A new report that examined soil, water, and produce from urban farms and gardens in Baltimore City found low levels of lead and other metals that pose no reason for concern at the majority of growing sites.
Protecting one of our most vulnerable populations, babies and young children, is among the U.S. Food and Drug Administration's highest priorities.
A new U.S. Geological Survey study provides an updated, statewide estimate of high levels of naturally occurring arsenic and uranium in private well water across Connecticut.
An estimated 6 million Americans may suffer from peanut allergies. Tiny amounts of peanut protein can lead to hives, itching, tingling in the mouth, shortness of breath or nausea within minutes.
The interiors of nonflowering trees such as pine and ginkgo contain sapwood lined with straw-like conduits known as xylem, which draw water up through a tree's trunk and branches.
The U.S. Food and Drug Administration takes exposure to toxic elements, such as arsenic, mercury, cadmium and lead, in the food supply extremely seriously, especially when it comes to protecting the health and safety of the youngest and most vulnerable in the population.
The MDI Biological Laboratory will collaborate with the Maine Center for Disease Control and Prevention, an office of the state Department of Health and Human Services, on a five-year grant from the federal Centers for Disease Control and Prevention, to improve access to safe drinking water in Maine.
Exposure to metals such as nickel, arsenic, cobalt and lead may disrupt a woman's hormones during pregnancy, according to a Rutgers study.
A new national study of public water systems found that arsenic levels were not uniform across the U.S., even after implementation of the latest national regulatory standard.
Those living in the Southwestern states of the US are more likely to be exposed to high concentrations of arsenic in their drinking water, a new study finds.
Lurking in sediments and surrounding the precious groundwater beneath our feet is a dangerous toxin: uranium. Scientists have long known this and tested for it.
Findings from a new study conducted by a team of researchers at Dartmouth's Geisel School of Medicine and published in the journal Preventive Medicine Reports, show that involving pediatric practices in the promotion of private well water testing can influence parental compliance.
Researchers at the University of Cincinnati have identified new clues into ways tobacco use impacts patients with kidney cancer.
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.
A group of medical and environmental researchers from RUDN University evaluated the level of heavy metals in the organism of first-year university students from different countries of the world.
Canada today announced a CDN$10 million extension of core funding through 2025 for the UN University Institute for Water, Environment and Health, a research organization at the forefront of pressing global water challenges.
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.
A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United States from 2012 to 2018.
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.
