PROVIDENCE, R.I. [Brown University] — In this study led by Mark Pitt, Professor of Economics and PSTC Associate, and his colleagues, they exploit a unique data set that allows for comparisons of arsenic (As) concentrations across genetically-linked individuals in non-coresident households and use innovative biomarkers to analyze individual arsenic burden. This study provides new estimates of the effects of dietary exposure to arsenic, and how arsenic ingestion and retention causally affect nutritional status, physical and cognitive capacity, and house- hold income, using toenail clippings obtained from a sample of members in rural households in Bangladesh.
