  • 273 - Susceptibility to Arsenic-Induced Skin Lesions Influenced by DNA Differences -- Ahsan
    Release Date: 09/06/2017

    New research shows that deletions or duplications of long stretches of DNA, also known as copy number variations (CNVs), that occur in several gene locations are associated with a higher risk of developing arsenic-induced skin lesions. Skin lesions are a hallmark of arsenic toxicity that appear relatively early with chronic arsenic exposure. This newly discovered link may help to explain why some people exposed to arsenic develop skin lesions and get sick while others exposed to the same levels do not.

  • 208 - A Flurry of Arsenic Findings -- Ahsan, Jackson, Lu
    Release Date: 04/04/2012

    New evidence about arsenic abounds in SRP studies published recently. The studies reveal that food is an unexpected source of arsenic exposure, demonstrate adverse health effects are from low levels of exposure, show the mechanisms behind some of arsenic's health effects, and suggest a strategy for reducing exposure from well water.

  • 187 - Chronic Arsenic Exposure Linked to Increased Mortality Rate -- Graziano, Ahsan
    Release Date: 07/07/2010

    A unique study involving nearly 12,000 participants offers strong evidence of an increased risk of death among those who drink water from sources with elevated arsenic levels.
