Arsenic in Rice and Other FoodsFebruary 27, 2014
Expert: Mary Lou Guerinot, Ph.D.
Arsenic poisoning is a recognized health threat worldwide. Although contaminated drinking water is a primary culprit, people can also be exposed to arsenic through foods. In this podcast, learn why rice and other foods sometimes contain arsenic and get tips on how to reduce your exposure.
Mary Lou Guerinot, Ph.D., is the Ronald and Deborah Harris professor of biological sciences at Dartmouth College and associate director of the Dartmouth Toxic Metals Superfund Research Program. Her research focuses on the molecular mechanisms of trace element uptake and its regulation. Her long-term goal is to understand how plants acquire trace elements from the soil and distribute them while protecting themselves from the potential damage such elements can cause to living tissues. As part of several multi-investigator projects, Guerinot is using ICP-MS (inductively coupled spectroscopy-mass spectroscopy) to examine the connections between a plant's genome and its elemental profile. She also uses SXRF (synchrotron x-ray fluorescence spectroscopy) to precisely localize various elements within living plant tissues.
