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)

Arsenic exposure could increase diabetes risk
Inorganic arsenic, commonly found in ground water in certain areas, may increase the risk of developing type 2 diabetes, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.   view more (2008-08-20)

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)

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 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)

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)

Calcite, a filter for water-borne arsenic?
An experiment at the Institut Laue-Langevin raises great hopes.   view more (2005-02-10)

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 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... view more (2003-08-26)

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)

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)

Store-bought freshwater fish contain elevated levels of mercury, arsenic and selenium
White bass wild-caught and sold commercially contained significantly higher levels of mercury, arsenic and selenium than fish caught near former industrial areas.   view more (2007-11-07)

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)

Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many... view more (2002-10-11)

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)

Living sensor can warn of arsenic pollution
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General... view more (2008-09-08)

Arsenic remedy for arsenic poisoning? - Homeopathic solutions for a global catastrophe
A homeopathic remedy made from arsenic oxide could ease the suffering of the hundreds of millions of people at risk from arsenic poisoning worldwide. Research, published this week in BMC Complementary and Alternative Medicine, suggests that Arsenicum Album reduces the liver damage caused by... view more (2003-10-17)

Arsenic contamination lacks one-size-fits-all remedy
Though a worldwide problem, arsenic contamination of drinking water does not have a universal solution.   view more (2007-12-11)

Arsenic aids tumor imaging when joined to cancer-homing drug, UT Southwestern researchers find
Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found.   view more (2008-03-03)

UNIVERSITY OF PLYMOUTH LEADS MAJOR RESEARCH PROJECT
The University of Plymouth is co-ordinating a two-year, £500,000 European research project that could lead to significant improvements in food safety standards and ensure healthier citizens. The project will investigate the use of selenium and the presence of arsenic in our diet. Involving 20... view more (2001-11-21)

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)

'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)
