Metal attraction: an ironclad solution to arsenic contamination?
Abstract:
Inorganic arsenic-the more acutely toxic form of this metalloid element-contaminates drinking water supplies around the world. In the United States, the most serious arsenic contamination occurs in the West, Midwest, Southwest, and Northeast; as many as 20 million people-many getting their water from unregulated private wells-may be exposed to excess arsenic in their drinking water. In Bangladesh, it's estimated that as many as 40 million people may be suffering from arsenic poisoning; contaminated drinking water is also a problem in many other countries, including Argentina, China, Chile, Ghana, Hungary, India, and Mexico.
