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)
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)
'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)
Geoscientists follow arsenic from chicken feed to streambeds
Organic arsenic is fed to poultry to prevent bacterial infections and improve weight gain. A little bit of arsenic is taken up by the tissue and the majority of it is excreted in urine. view more (2005-10-12)
Arsenic discharged from landfills, says Dartmouth research
A group of researchers at Dartmouth have studied the concentrations of toxic metals at the former Coakley Landfill in North Hampton, N.H. They've found that while the level of iron and some other contaminants decreased, the level of arsenic slightly increased. view more (2005-12-05)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
Nanoscientists Provide New Picture of Semiconductor Material
For almost a decade, scientists thought they understood the surface structure of cubic gallium nitride, a promising new crystalline semiconductor. view more (2005-10-05)
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)
Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy
Environmental arsenic pollution is a serious and growing environmental problem, especially on the Indian subcontinent. Researchers at the University of Georgia had, several years ago, used genetic techniques to create "arsenic-eating" plants that could be planted on polluted sites. view more (2006-04-12)
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)
NIST releases new standard for semiconductor industry
A wide range of optical electronic devices, from laser disk players to traffic lights, may be improved in the future thanks to a small piece of semiconductor, about the size of a button, coated with aluminum, gallium, and arsenic (AlGaAs). view more (2006-10-13)
Arsenic in chicken feed may pose health risks to humans, C&EN reports
Pets may not be the only organisms endangered by some food additives. An arsenic-based additive used in chicken feed may pose health risks to humans who eat meat from chickens that are raised on the feed. view more (2007-04-10)
Aussie arsenic-eating bacteria may save lives and clean mines
Melbourne scientists plan to harness the strange appetite of newly discovered Australian bacteria to help purify arsenic-contaminated water. The research group, led by microbiologist Dr Joanne Santini of La Trobe University, is working out how to use bacteria that eat arsenic to clean up contaminated wastewater in Australian and overseas mining... view more...

Risk for skin lesions increases with low-dose exposure to arsenic in drinking water
Millions of persons around the world are exposed to low doses of arsenic through drinking water. However, up until now estimates of the health effects associated with low-dose exposure had been based on research from high-dose levels. view more (2006-06-15)
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)
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)
'Racetrack' for fast electrons in semiconductor structures
In order to realize the electrical units of voltage, resistance and current with highest accuracy quantum effects in nano-circuits are nowadays used. Important prerequisites are extremely pure semiconductor layers where high-mobile electrons move through the crystal without collision with residual impurities. view more (2008-08-29)
Dartmouth study finds that arsenic inhibits DNA repair
Dartmouth researchers, working with scientists at the University of Arizona and at the Department of Natural Resources in Sonora, Mexico, have published a study on the impact of arsenic exposure on DNA damage. view more (2006-05-30)
Dartmouth researchers show effects of low dose arsenic on development
A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. view more (2007-11-15)
Delft University of Technology shines light on atomic transistor
Researchers from Delft University of Technology and the FOM Foundation (Fundamental Research on Matter) have successfully measured transport through a single atom in a transistor. view more (2006-11-27)
