Our group studies the toxicological effects of acute and chronic arsenic exposure at multiple levels of organization, with a primary focus on cardiovascular and metabolic perturbations. We are conducting a ongoing study in rural Bangladesh, where endemic arsenic exposure via tube well water consumption is consistently high. Our initial research trip (December 2013 – January 2014) focused on identification of susceptible populations in the Shariatpur district of Southern central Bangladesh, involving collection of tube well water, biological samples, assessment of clinical signs of arsenicosis, and administration of health effects surveys. Future visits will expand the study, with refined clinical assessments and survey subclinical cardiovascular and metabolic biomarkers of arsenic exposure.
