Dartmouth researchers show effects of low dose arsenic on development

A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. The finding is further evidence that arsenic at low doses (at levels found in U.S. drinking water in some areas) can be harmful. The study appeared in the Oct. 26, 2007, online edition of the journal Environmental Health Perspectives (EHP), and it will be published in a forthcoming issue of the journal.
