Water quality in South Asia Scientists solve puzzle of arsenic-poisoning
A team of scientists led by Stanford University soil scientist Scott Fendorf says bacteria cause the absorption of high levels of natural arsenic into groundwater in South Asia from the natural arsenic flowing down from the Himalayan mountains. The results are published in the latest issue of the journal Nature. The World Health Organization has blamed the arsenic for high rates of cancer in India, Bangladesh, Myanmar, Cambodia, and Vietnam.
In a news report on March 24 by Stanford News Service, Fendorf has solved the puzzle of how and why the natural arsenic was somehow working its way into the groundwater more than 100 feet below the surface, instead of remaining chemically trapped in the river sediments.
