Dartmouth researchers alarmed by levels of mercury and arsenic in Chinese freshwater ecosystem
A team of researchers, led by biologists at Dartmouth, has found potentially dangerous levels of mercury and arsenic in Lake Baiyangdian, the largest lake in the North China Plain and a source of both food and drinking water for the people who live around it. view more (2008-01-10)
Dartmouth researchers find that low doses of arsenic have broad impact on hormone activity
Dartmouth Medical School investigators are learning more about how low doses of arsenic, such as the levels found in drinking water in many areas of the United States, affect human physiology. view more (2006-12-05)
Treated wood poses long-term threat
Arsenic from treated lumber used in decks, utility poles and fences will likely leach into the environment for decades to come, possibly threatening groundwater, according to two research papers published online Wednesday. view more (2005-12-27)
Folic acid lowers blood arsenic levels, according to Mailman School of Public Health study
A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water. view more (2007-10-08)
'Nanorust' cleans arsenic from drinking water
The discovery of unexpected magnetic interactions between ultrasmall specks of rust is leading scientists at Rice University's Center for Biological and Environmental Nanotechnology (CBEN) to develop a revolutionary, low-cost technology for cleaning arsenic from drinking water. view more (2006-11-10)
Argonne scientists use unique diamond anvils to view oxide glass structures under pressure
Researchers at the U.S. Department of Energy's Argonne National Laboratory have used a uniquely-constructed perforated diamond cell to investigate oxide glass structures at high pressures in unprecedented detail. view more (2007-11-09)
MIT: Prenatal arsenic exposure detected in newborns
MIT researchers have found that the children of mothers whose water supplies were contaminated with arsenic during their pregnancies harbored gene expression changes that may lead to cancer and other diseases later in life. view more (2007-11-26)
Folic acid lowers blood arsenic levels in Bangladesh
A new study conducted in Bangladesh finds that folic acid supplements can dramatically lower blood arsenic levels in individuals chronically exposed to arsenic-contaminated drinking water. Arsenic is a toxic element that is naturally present in some soils and water. view more (2007-10-11)
Cancer death rates remain high decades after exposure to arsenic
Death rates from lung and bladder cancer remained high decades after residents in northern Chile were exposed to high levels of arsenic in their drinking water. view more (2007-06-13)
Montana State team finds Yellowstone alga that detoxifies arsenic
Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. view more (2009-03-10)
Scientists simulate gut reaction to arsenic exposure
A simulated gastrointestinal system is helping scientists test contaminated soil for its potential to harm humans. The method is likely to save time and money for people hoping to repurpose land with an industrial past. view more (2008-10-08)
Queen's researchers provide solution to world's worst mass poisoning case
A solution to the world's worst case of ongoing mass poisoning, linked to rising cancer rates in Southern Asia, has been developed by researchers from Queen's University Belfast. view more (2008-08-29)
Biosensors to probe the metals menace
Researchers from CRC CARE are pioneering a world-first technology to warn people if their local water or air is contaminated with dangerous levels of toxic heavy metals and metal-like substances. view more (2007-08-30)
Study finds in utero arsenic exposure tied to lung disease
Children who are exposed to high levels of arsenic in their drinking water are seven to 12 times more likely to die of lung cancer and other lung diseases in young adulthood, a new study by University of California, Berkeley, and Chilean researchers suggests. view more (2006-03-29)
UC Davis study finds high arsenic levels in herbal kelp supplements
A study of herbal kelp supplements led by UC Davis public health expert Marc Schenker concludes that its medicinal use may cause inadvertent arsenic poisoning and health dangers for consumers, especially when overused. Schenker and two researchers evaluated nine over-the-counter herbal kelp products and found higher than acceptable arsenic levels... view more... (2007-04-09)
MIT scientists pinpoint origin of dissolved arsenic in Bangladesh drinking water
Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. view more (2009-11-16)
Dartmouth researchers find that arsenic triggers unique mechanism in rare leukemia
Dartmouth Medical School (DMS) researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan. 3 issue of the Journal of the National Cancer Institute. view more (2007-01-09)
Nanotube-producing bacteria show manufacturing promise
Two engineers at the University of California, Riverside are part of a binational team that has found semiconducting nanotubes produced by living bacteria - a discovery that could help in the creation of a new generation of nanoelectronic devices. view more (2007-12-10)
Ayurvedic medicines sold via Internet may contain lead, mercury or arsenic
An analysis of Ayurvedic medicines (based on a traditional medical system commonly used in India) purchased via the Internet found that one-fifth of these products contain levels of lead, mercury or arsenic that exceed acceptable standards, according to a study in the August 27 issue of JAMA. view more (2008-08-27)
Paint used by Dutch masters turns into rat poison
The painters Willem Kalf, Jan Davidsz. de Heem and Balthasar van der Ast are particularly famed for their bright yellow orpiment ("royal yellow"). The researchers have shown that light causes a chemical reaction in this yellow which separates the sulphur and the arsenic. The sulphur is released from the canvas as sulphur dioxide and hydrogen... view more... (1999-05-17)
