SUMMARY:Tracing the Dynamic Distribution of Arsenic Across Reservoirs
DESCRIPTION:Speaker:  Athena Nghiem\, Assistant Professor of Geoscience\, 
 UW–Madison\n\n\n\nArsenic (As) is a naturally-occurring trace element\, 
 with an environmental distribution that has been greatly modified by human
  activity. Importantly\, As carries a significant threat to human health\,
  due to its toxicity and likelihood of exposure. A widely-recognized\, but
  localized exposure source is the use of As-contaminated groundwater. The 
 atmosphere represents another\, and more regional\, exposure route. Arseni
 c emitted from natural and anthropogenic sources can undergo long-range tr
 ansport that leads to deposition in susceptible environments. However\, wh
 ile anthropogenic emissions have been consistently estimated\, estimates f
 or natural emissions vary by over three orders of magnitude. In this talk\
 , Nghiem will explore As biogeochemical cycling in multiple reservoirs\, i
 ncluding closing the knowledge gap on global atmospheric As cycling. Ultim
 ately\, Nghiem’s aim is to determine the redistribution and legacy impac
 ts of As in the environment between reservoirs by using a diversity of app
 roaches.\n\nView the livestream
