Field Measurements for Reducing Toxic Environmental Exposures in Developing Countries
Tuesday March 1st
Room 417 Schermerhorn Hall
Summary: Using examples from two on-going field studies, I will show how more widespread use of relatively simple field kits could dramatically reduce human exposure to arsenic in groundwater in Bangladesh and to lead from mine tailings in Peru.
Dr. Lex van Geen is Lamont Research Professor and geochemist at Lamont-Doherty Earth Observatory. Lex's research focusses on geochemical cycling of trace elements in natural and perturbed environments, particularly redox-sensitive processes affecting metals and metalloids. His studies have applications to mine tailings, coastal sediment, estuaries, and groundwater, as well reconstructions of past climate change in nearshore environments. More recently Lex's interests have begun to bridge disciplines, including the health and social sciences, in oder to better address multi-faceted environmental problems.
Lex double majored in chemistry and oceanography at the University of Washington, and completed his Ph.D. in the MIT/WHOI Joint Program in Oceanography.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
