Arsenic in Asian Drinking Water Linked to Microbes

Publication: National Geographic News   Date: June 30, 2004   View Article

Microscopic organisms that get their energy by inhaling metals in the ground play a key role in the arsenic poisoning of drinking water for millions of people in Bangladesh and the Indian state of West Bengal, according to a new study.

Researchers hope that the finding will shed light on how the drinking water came to be so heavily laced with arsenic—and that, in turn, it is hoped, could yield a way to reduce the level of the toxin.
