  • Arsenic poisoning from drinking water

    A study published in The Lancet this month calculated mortality rates associated with arsenic exposure from drinking water in a Bangladeshi population. Individual-level data was used to determine that 21.4% of all deaths and 23.5% of deaths associated with chronic disease in this population could be attributed to arsenic exposure. Millions of people worldwide are chronically exposed to arsenic ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns.
