    Battling ‘the Largest Mass Poisoning in History’

    As many as one in five deaths in Bangladesh may be tied to naturally occurring arsenic in the drinking water; it is the epicenter of a worldwide problem that is affecting tens of millions of people. For two decades, health specialists and earth scientists from Columbia University have been trying to understand the problem, and…
