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.
Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels.
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.
Significant amounts of toxic metals, including lead, leak from some e-cigarette heating coils and are present in the aerosols inhaled by users, according to a study from scientists at Johns Hopkins Bloomberg School of Public Health.
People from two indigenous communities in the Peruvian Amazon who live close to the country's longest oil pipeline have mercury, cadmium and lead in their bodies at concentrations that could be harmful to their health.
Using nuclear medicine, German researchers have found a way to accurately differentiate cancerous tissue from healthy tissue in prostate cancer patients. The research is highlighted in the February issue of The Journal of Nuclear Medicine.
Dr. Bob Clifford has published and presented over 125 papers in the fields of food, pharmaceutical, environmental, energy, geology, material science, photonics, and cannabis. However, his true love is in food.
After graduating with his Ph.D., he left his job with the FDA for Shimadzu where he has worked for the last 26 years.
Dr. Megan Rockafellow-Baldoni, Rutgers School of Public Health alum and Center for Public Health Workforce Development program coordinator, has found a reduction in the risk of cancer due to arsenic exposure in Hopewell Township (Mercer County), New Jersey with use of arsenic treatment systems. Arsenic exists in varying levels in all parts of New Jersey; chronic exposure can increase rates of bladder, lung, liver, kidney, and skin cancers.
A new study reports that chronic exposure to arsenic interferes with insulin secretion in the pancreas, which may increase the risk of diabetes.
Sleeping sickness could use a more encompassing moniker. An international study from the O'Donnell Brain Institute shows one of Africa's most lethal diseases is actually a circadian rhythm disorder caused by the acceleration of biological clocks controlling a range of vital functions besides sleep.
Even though men use tanning beds at lower rates than women, men who tan tend to do it in riskier ways, according to a study by researchers at the University of Connecticut. The findings should help public health officials rethink how, and to whom, they're targeting anti-tanning messages.
A latest study has uncovered a scary fact – nearly 80 percent of infant formulas and baby foods have tested positive for Arsenic content.
A new paper published in the Journal of the National Cancer Institute shows that arsenic in drinking water may have one of the longest dormancy periods of any carcinogen.
New research conducted at Columbia University's Mailman School of Public Health found that exposure to arsenic in drinking water was significantly reduced among Americans using public water systems following the Environmental Protection Agency regulation on maximum levels of arsenic.
From Sherlock Holmes to Agatha Christie, arsenic is often the poison of choice in popular whodunits. But in ultra-low dosage, and in the right form, this naturally occurring chemical element can be a potent force against cancer.
A region of vast expanses and unparalleled natural beauty, the southwestern United States is a land of harsh socioeconomic realities for many, especially for underserved Native American and Hispanic populations.
Two Montana State University researchers in different disciplines have teamed up to tackle the problem of arsenic poisoning, which is estimated by the World Health Organization to affect more than 100 million people worldwide, primarily through tainted drinking water.
Underground drinking water sources in parts of the U.S. and three Asian countries may not be as safe as previously thought due to high levels of manganese, especially at shallow depths, according to a study led by a researcher at the University of California, Riverside.
Analysis of water supplies in Pakistan has shown abnormally high levels of Arsenic putting 60 million residents at risk of Arsenic poisoning. The study evaluated and analyzed around 1,200 groundwater quality samples from various parts of the country. Over the Indus plain the results show levels of Arsenic that are way above the World Health Organization (WHO) safety guidelines’ recommendations. The study was published in the journal, Science Advances.
Latest global estimates illustrate the vast impact of the two most common chronic respiratory diseases, with 3.2 million deaths from chronic obstructive pulmonary disease (COPD) and 0.4 million deaths caused by asthma in 2015, according to a new Global Burden of Disease study published in The Lancet Respiratory Medicine journal.
Pediatricians and public health researchers know they have to be on the lookout for lead exposure from paint chips and contaminated drinking water. A new report suggests food — particularly baby food — could be a problem, too.
